New Air Conditioning Installation Guide

Keeping your cool when your air conditioning goes out in your home or business is hard to do in throes of summer. If your current air conditioner isn’t cooling the way you think it should be, it may be time to replace it.

Air Conditioning Installation

How do I know if my unit needs to be repaired or replaced?

When working properly, air conditioners fade into the background of our everyday lives. However, when common warning signs—lack of cool air, limited air flow, moisture buildup, frequent cycles, bad odors, and strange sounds—start occurring, it’s time to bring in a certified A/C contractor. He or she can help you determine if your unit needs to be repaired or replaced.

When should I replace my air conditioner?

Most anything can be repaired, but at some point it becomes financially prudent to replace it. Consider these points:

  • Age – A typical A/C unit has a life span of about 10 to 15 years. If your unit is acting up and it’s over 15 years old, the better option is to replace it.
  • Cost – Use this simple formula to determine if the repair cost is too high: multiply the estimated cost of the repair by the age of your unit (in years). If the result is more than the cost of a new unit, it’s time to replace your unit.
  • Energy Bills – If your energy bills keep rising but your electrical utility company hasn’t raised their rates, it may be time to replace your unit.
  • Efficiency – If you’re A/C is running all the time or some rooms feel hot no matter what you’ve set your thermostat to, it may be time to replace your unit. For more on balancing hot and cold rooms check out 7 Ways to Fix Hot and Cold Rooms 
  • Refrigerant Type – To protect the ozone layer, the federal government mandated that Freon no longer be produced after January 2020. As the supply of Freon gets scarcer, the cost to recharge older A/C units still using it will increase significantly. If your current unit uses freon—commonly used in systems prior to 2004—it’s time to replace it.
  • Stage of Life – If you are retiring soon, the last thing you want to do is call for repairs each year on an old AC unit. Consider replacing the unit before you’re living on a fixed income.
  • Go with Your Gut – Sometimes you just know what the right thing to do is. If you feel something’s just not right with your current unit, consider replacing it.

What are my options for new A/C equipment?

Thanks to new technology, today’s A/C systems use much less electricity when compared to older models. A new, high-efficiency air conditioning system you will save money on electricity bills each month while making your home more comfortable. Depending on your cooling needs, you can select from various units.

Most residential air conditioners are split systems whereby a compressor pumps refrigerant into an evaporative coil. As the refrigerant cools the evaporative coil, a fan blows air through the evaporator coil and distributes it to the duct work or room. Another cooling option is an evaporative cooler—sometimes known as a swamp cooler—which works by water passing over a pad or filters and then a motor and fan blowing water-cooled air into a room. A third option is a ductless A/C system—also called a mini-split A/C system—that uses a thin copper pipe to pump refrigerant directly to a wall-mounted blower in a room. A Day & Night Mechanical certified technician can assess your cooling needs and recommend the right unit for your space. 

How can I save money and/or finance a new A/C system?

Day & Night Mechanical partners with Xcel Energy to offer high-efficiency A/C units with qualifying rebates. For example, you could earn rebates up to $500 for A/C split systems and up to $300 for mini splits. In addition, financing options from Synchrony, AMS Financial, and FTL finance , online coupons, and senior and military discounts can further low the cost of a new A/C unit.

How Can I Get the Airflow Even in My House?

7 Ways to Fix Hot and Cold Rooms 

Does your home resemble the Goldilocks’ fairy tale—one room’s too hot, one’s too cold, while another is just right? You can put that fairy tale to bed by following a few simple tips:

Check Filters for Cleanliness

Keeping your filters clean improves your home’s air quality, increases your furnace’s efficiency, and extends the life of your HVAC system. Dirty filters reduce airflow, forcing your HVAC system to work harder thus causing the system to overheat and shut off too quickly. A clean filter allows your system to run more efficient; regularly changing your filter can save you five to 15 percent on your utility bill.

Install Window Coverings to Prevent Heat Build Up

Adding blinds and shades to your rooms not only adds style but helps keep heat from building up in rooms facing east, west, and south. Just remember to close or pull them down whenever the sun is shining!

Prevent Airflow Restrictions

Many people think closing air supply vents in unused rooms saves money. Don’t fall for this old wives’ tale! Closing a vent only blocks air from getting into the room and causes damage to your HVAC and duct systems. If you have a room that needs less heating or cooling, you can partially close the register but don’t close it all the way. Also, be sure vents are not blocked by furniture, rugs, and drapes; allow at least 18” of space around each vent.

Place Thermostat Fan Setting to ON

If you have an ON fan setting on your thermostat, use it! By using this setting, the fan blows continuously thereby filtering and replacing indoor air. NOTE: This only works if you have an ECM motor. A standard motor should remain in the Auto setting.

If you find you are still having issues, you may need to evaluate a more extensive option:

Fixing Your Duct Work

Ductwork inefficiencies such as improper size or leaks can cause uneven distribution resulting in hot or cold spots in your home. A trained technician from Day & Night Mechanical Solutions can inspect your home’s ductwork and fix either or both of these problems.

Going Ductless

As the name implies, a ductless heating system does not require the use of air ducts. Inexpensive to install in almost any setting, the system uses highly efficient zonal heating by allowing independent control over each area. Perfect for homes with open floor plans—one indoor unit can heat an entire large living space—they also improve indoor air quality by constantly circulating fresh, healthy air rather than dust that has built up in the ductwork.

Using Two Air Handlers

Electric heating and cooling systems consist of two main parts—an outdoor unit and an indoor unit, or air handler. When matched with a heat pump, the air handler circulates both cool and hot air, depending on the season. Properly sized air handlers provide the right amount of clean, comfortable air year-round. The more efficient the air handler is, the less work the outdoor unit has to do to make your home comfortable. A trained Day & Night Mechanical Solutions technician can inspect your current system and see if a second air handler is right for your home.

Many of the air flow tips are easy and can be done today. Start with the easy ones. When in doubt, get a professional opinion from a trained HVAC technician at Day & Night Mechanical Solutions. Call us today at 303-936-2696 to provide comfort throughout your home.



Does My HVAC System Need a Tune-Up?

Denver’s weather is crazy. One day it is 80 degrees and sunny and the next we have a bomb cyclone moving in. Have you ever had your heating go out in the dead of winter or your air conditioning quit on the hottest day of the year? 

Heating and air conditioning equipment should be cleaned, inspected, and serviced at least once a year. The best scenario is to service your air conditioner in the spring and your heat system in the fall. Tuning up each piece of equipment annually helps avoid disruption in service and costly repairs. Prolong the life span of your HVAC system and maintain a safe and healthy operation for your family with annual tune ups.

In the spring, we recommend a tune up of your air conditioning system.

What is Included in an Air Conditioning Tune-Up?

Furnace Fitness: Tips to a Healthy Furnace

There is nothing worse than waking up to or walking into a cold house due to furnace failure. While all furnaces inevitably wear out, there are things you can do to help extend your furnace’s life and efficiency.

One of the best and easiest ways to maintain an efficient furnace and boost its longevity is to schedule an annual inspection and tune up every fall before you first turn on your furnace. Here the old cliché, an ounce of prevention is worth a pound of cure, certainly applies. The furnace professionals at Day & Night Mechanical Solutions in Denver are trained to do a multi-point inspection and cleaning.

Other maintenance checks and tasks you can perform yourself include:

  • Replacing the furnace filter at least every 90 days—but check it monthly for signs debris buildup
  • Checking the furnace flame color periodically—if you see any other color than blue with maybe a small yellow tip, call Day & Night Mechanical Solutions
  • Clearing the area around the furnace—a three- to five-foot perimeter allows air to circulate freely
  • Clearing intake and exhaust vents and drain line outlets

In addition, there are things you can do to boost your furnace’s efficiency:

  • Programming your thermostat to lower the temperature when you leave home for a long period of time or go to bed; a simple 5-day/2-day programmable thermostat is not expensive and is easy to install
  • Ensuring your registers are clear of furniture and are open and free of debris
  • Using ceiling fans—run on low speed in clockwise direction—to push naturally rising hot air down to the floor
  • Using a humidifier to bring your home’s humidity level up to about 40 percent; it makes the air feel warmer
  • Ensuring your garage door—one of the biggest culprits of energy loss—is all the way down and there are no drafts around the sides or top
  • Using curtains at night to prevent heat loss and opening them during the day in south- or west-facing windows to allow warm sunshine to enter and heat your home

Like your car or any other machine or appliance, the less wear and tear your furnace gets—through regular tune ups and increasing efficiency—the longer it will last. Having a longer lasting furnace running at peak efficiency saves you money—twice!

At Denver-area Day & Night Mechanical Solutions, our goal is to provide you with the highest quality HVAC services possible. Our furnace experts have years of experience and stand ready to inspect and tune up your gas furnace. Call us today at 303-936-2696.


When Should I Replace My Furnace? 

This time of year, a warm and comfortable home is essential. It’s easy to forget about the furnace that makes that a reality for your home…until it stops working.
Take a minute to think about your home’s fiery friend. How’s it doing? Is your house warm throughout and your energy bills in line with what you think they should be for this time of year? Or are you having to make more frequent and expensive repairs and paying sky-high energy bills while shivering in an extra layer of clothing?
If you’re nodding yes to the last question, it may be time to replace your furnace and install anew high-efficiency unit. Here are warning signs indicating it may be time to replace your furnace:
1. Your Furnace is Approaching its Lifespan
Regularly maintained furnaces can last 15-20 years or more but each furnace has a life span. If your furnace is approaching that age range, it may be time to start shopping for a replacement. Waiting until it breaks forces you to shop in emergency mode, possibly limiting your shopping options and preventing you from finding the best furnace for your family’s needs.
2. Your Energy Bills Have Increased
Many older furnaces have to work harder to provide the level of heating they did when they were new. If you find your energy bills are increasing significantly, it may be time to look at a new high-efficiency furnace.
3. Your Furnace Has Been Repaired Many Times over the Last Two Years
An increase in the frequency that you call a repairman for something other than regular maintenance may indicate it’s time to replace your furnace. Here’s a good rule of thumb when considering whether to repair or replace a furnace: if the cost to repair a furnace is 50 percent of the cost of a new furnace, you should replace it. However, keep in mind the furnace’s age even when a repair is less expensive. If your furnace is 20+ years old, you may want to replace it because it is more likely to break down again soon.
4. You Hear Strange Noises When the Furnace is Running
While it’s funny to hear the agitated dad in the movie A Christmas Story fussing and cussing at the clunky furnace in the cellar, popping, banging, humming, or screeching noises coming
from your furnace is no laughing matter. Furnaces do make some noise when they turn on and off but if the noise gets progressively louder or you hear a noise you’ve never heard before, it may be time to replace the furnace.
5. You’re Never Comfortable, No Matter What the Setting is on the Thermostat
If some rooms are colder or warmer than others, it may be that the furnace and duct system are losing their ability to distribute heat evenly throughout your home. Additional warning signs include the furnace turning on and off frequently and/or blowing cold air.

6. Your Burner Flame is Not Blue
When burning fuel efficiently, a furnace’s flame should be blue. Any flame color other than blue may indicate incomplete combustion and could be a potentially dangerous situation such as leaking gas and/or carbon monoxide. Note: If family members suddenly start complaining of headaches, restlessness, or drowsiness, leave your house immediately, call the utility company to turn off your gas, and have a repairman check the furnace.
7. There is Soot Around the Floor Registers
Older furnaces may spew out dust, dirt, or rust particles. While aggravating to a neat freak, the more important issue is that this can be dangerous to everyone’s health. Excessive soot around floor registers poses a fire hazard and increases the risk of carbon monoxide poisoning. As with item 6 above, if you suspect your furnace is producing carbon monoxide, leave your house immediately, call the utility company to turn off your gas, and have a repairman check the furnace.
How many of these warning signs apply to your furnace? The more that apply, the more you should consider replacing it. Contact the furnace experts at Day and Night Mechanical Solutions to help you find the best money-saving, high-efficiency heating system for your heating needs.

Need a New System? Think Ductless.

girl in cold houseIf your heater or air conditioner has finally kicked the bucket, searching for a new system can be a lengthy process. But with winter right around the corner, you may not have as long as you need to find the perfect system. To help you narrow down a few great choices, we detail the benefits of ductless systems here.

  • Space saving. Adding a ductless system to a new room or a detached garage instead of constructing air ducts saves time, money, and allows you to utilize your room sooner.
  • Cost efficient. Ductless heaters are some of the most efficient in the entire industry. Less energy consumption means lower electric bills!
  • Painless installation. Ductless systems need only to be mounted and plugged in to begin use. This can bind you out in a pinch if your heater suddenly quits!
  • Purified air. By forgoing air ducts that often house mold and other irritants, ductless systems provide cleaner, safer air.

Denver’s Go-To HVAC Technicians

If you are looking for a replacement HVAC system, work with Denver’s top HVAC technicians to find the best system for your home needs.

frosty pineconeFall is here and chilly weather is upon us! Now we are relying on our homes and our heaters to protect us from the elements. Don’t take your chances with a spotty, temperamental heater – schedule a quick tune up to ensure you stay warm all winter long. Even if your system is only a few years old, a tune up will help preserve your system and allow it to live out its full potential.

A quick tune up will keep your system in top shape. A trained technician knows the exact spots to look for that could potentially cause trouble during the frozen winter – inspecting your thermostat, the power connections to your heater, and its ignition will keep your heater running at peak efficiency. If your heater emits a burning smell when it first begins to operate, a technician will able to help troubleshoot this problem and keep you breathing clean air.

Heating Help

Not only will a tune up help your system perform its best, but it can also help you save on utility costs: a heater that works overtime to compensate for its issues often draws on more electricity and increases utility bills. Don’t wait until you’re face to face with a fried heater in the dead of winter – counter the issues before they start! 

The Importance of Clean, Healthy Indoor Air

clean indoorsIt is no secret that our homes and businesses can recirculate dirty air that is tainted with smoke, pet dander, dust, and mold. But did you know that the EPA considers indoor air pollution to be one of the top 5 environmental threats to public health? Now, consider how many hours a day that you typically spend inside, and you can imagine how important it is to be breathing clean, safe air. To help you breathe easier, we briefly walk through the basics of several types of air cleaning systems.

The type of air system that your home or business is equipped with will contribute to what type of air cleaner your system has. Traditional heating and cooling systems usually clean their air with filtersthat are manually changed and serviced. However, these filters simply trap dust and fibers without purifying the air, so it is important to regularly change the filter to prevent it from clogging and recirculating dirty air.

More current systems are outfitted with filters as well as purification systems, such as supplemental air purifiers or UV germicidal lamps. Many of these modern air cleaning technologies are available for installation regardless of the type of system in a home or a business.


Servicing Your Ductless Heater for Fall

A ductless heater is easily installed in any setting. If your HVAC system heats your house unevenly, a ductless heater is a great solution to supplement a room that needs additional heat or cool air. By circulating fresh air and forgoing ducts that can become dirtied with mold and dust, a ductless system can help improve the air quality in your home.

Ductless systems are one of the most efficient systems available, meaning they also help save money on utility bills. They are quiet and easy to install so there is no damage to the wall. Best of all, they are inconspicuous, so they do not command attention and are easy on the eyes.

Maintaining Your Heat & AC: Checklist to a Healthy System

winter, houseHomeowners want to know how best to care for their investments. Considering that air conditioning and heating systems play such a large roll in overall comfort, system maintenance will ensure absolute running efficiency. Setting aside less than an hour every month to perform a few routine procedures will help keep energy costs down and allow your system to perform at peak efficiency.

STEP 1: Clean or Change Air Filters

Whether your system uses disposable or reusable filters, it is important they be maintained to allow your system to breathe better.

Disposable filters: change every 30 days
Reusable filters: wash every 30 days
Keeping your filter clean will prevent system malfunction, increases in your energy bills, and reductions in the life expectancy of your system. Click here for more information on benefits of high performance filter options that may be available for your system.

STEP 2: Maintain the Outdoor Unit

First, shut the power off to your outdoor air conditioning unit, either at the breaker and/or at the disconnect box. Spray the air conditioner coil down with a hose to clean off any debris. If you have cottonwood trees close by, you may need to do this several times each spring. Trim bushes away 18” from the air conditioner to prevent a restriction of air to the unit. It may be necessary to use professional coil cleaner to remove built up pollution on the coil. Do not use household chemicals that could cause corrosion damage to the coil. It is best to have a professional perform this when needed.

STEP 3: Check the Indoor Unit

Check that there are no water leaks and that the system is draining properly. Turn the unit on and let it run for about 15 minutes, periodically checking for any visible water leaks. Water build-up (due to the condensation on your indoor unit’s plumbing) is nothing to be nervous about. However, if there is a significant accumulation due to a broken, loose or malfunctioning part, your problem could eventually turn into a costly repair. In addition, blockages inside your pipes can also become hazardous to your system. If your system is leaking water in any significant way, call a service technician immediately.

While these three steps will help to keep your system in proper running order, the best way to save money and avoid system malfunctions is professional, seasonal tune-ups. For professional heating and air conditioner service that fixes the problem the first time.

Your Thermostat and Energy Savings

saving moneyWhat comes to mind when you think about saving money on heating and cooling costs? Maybe you think of shiny new appliances with massive price tags, or turning off the heater and shivering through the night? While most of us find these options unfavorable, there are a few simple ways to save on heating and cooling all year round without sacrificing your comfort or your budget.

Use your thermostat, especially programmable thermostats, to take control of your utility bills. Are you working during the week from 9 to 5, or do you work a varied schedule? Perhaps you’ll be out running errands for a few hours. Program your thermostat, or manually control it, to save money and energy while the house is empty. Want to control your programmable thermostat with your phone while you’re away? There’s an app for that!

You can further save money and energy by setting the temperature a few degrees higher in the summer(near 78) and a few degrees lower in the winter (near 68). This small change in temperature reduces energy use without disturbing your comfort.

Lots of Savings With a Little Effort

If you are ready to start saving energy with your heating and air conditioning systems.

Using Space Heating

space heaterSpace heaters are a common sight in many homes during the frosty fall and winter months. While they are a sure way to keep warm, using a space heater incorrectly can be costly to your electric bill and dangerous for you and your family. Here are some quick tips to help you stay warm and safe in the upcoming months.

In comparison to whole home heating systems, space heaters are simply not as efficient. Whole home heating systems are able to distribute heat evenly throughout a house – space heaters are designed to heat certain spots. If you were to shut off your whole home heating system and use only space heaters, your home would not be nearly as warm and quite a bit of electricity would still be used. However, this spot-heating ability of space heaters can be a supplement to your home heating system to help you save money:instead of spending money to blast the heat in your whole house to make one area warmer, you can more efficiently heat this one spot with a space heater.

Space heaters carry an increased burn and fire risk, so using these appliances safely is key. All objects, pets, and people should be kept at least 3 feet away from the heater. The burn and fire hazards from space heaters are very real, so safety should not be overlooked when using these heaters.

Warm All Season Long


The 92% Rule and Your Furnace

heating valvesThe Department of Energy has recently proposed an increase in energy efficiencyfor non-weatherized gas furnaces. In 2011, the efficiency standard was 80% to 90% depending on the region of the country, while the proposed increase is a uniform 92%. How would this increase affect your heating systems? Here, we have delved into the effects of an energy efficiency increase.

Heating is the largest energy expense in U.S. homes, accounting for about 40% of utility bills. With the hefty economic and environmental impacts heating has, it is clear why the DOE is regulating the efficiency of heating systems. Increasing energy efficiency of furnaces can reduce wasting fuel to power the inefficiencies of heating systems, and also reduce harmful emissions from fuel burning.

How Would an Efficiency Increase Affect My System?

If enacted, an energy efficiency increase would not require all furnace owners to replace their existing systems. This rather means that new systems sold and installed must be at least 92% efficient. While this increased efficiency would indeed reduce unnecessary fuel usage and harmful emissions, the costs may surpass the benefits. The energy savings from 92% efficient systems may never pay for the cost of the system itself. In addition, in the event that a furnace must be replaced, many Americans may struggle to afford these pricey systems, pushing them to continue using unreliable, substandard, and often unsafe systems.

What are your thoughts on an energy efficiency increase for furnaces? Final word on this proposed increase should arrive around December 2015, so for professional heating and cooling in the meantime.
