The Importance of Quality AC Installation

Proper air conditioning installation is essential for the comfort of your family and the energy efficiency of your home. Only a professional installation will ensure that you get the best from your system—with the most effective cooling and lowest energy bill.

Your air conditioning installation should be dependable, function smoothly during the hot summer months, and require little maintenance. With a properly installed, durable AC system, your home’s climate is effortlessly controlled, providing maximum comfort for minimum cost.

What Are The Benefits of Replacing Your Air Conditioning Unit?

When you find out you need AC replacement, you likely will not be thrilled with the idea initially. However, once you learn the benefits you’ll get from replacing your old air conditioner with a new, efficient model, you’ll start coming around to the idea.

According to the U.S. Department of Energy, you can save between 20% and 40% on your cooling bill annually by replacing your central air conditioner. With proper care, a central air conditioner should last about 15-20 years, so if yours is getting up there and you’re looking at a hefty repair bill, it might be a better move to just go with AC replacement.

AC Replacement Considerations

If you have added space to your living quarters — either by finishing an attic, basement or garage, or by putting on an addition — replacing your unit with a larger one that is better suited to your new square footage can keep your family more comfortable without running up your electric bill.

Although we leave the final decision with you about whether to repair or replace your AC, we give you our professional recommendation, based on the age of your current unit and how much more time we expect the repair would buy you.

What Are Signs You Need AC Replacement?

Several signs may indicate when it could be time to replace an aging AC unit. First, if your AC unit is more than 10 to 15 years old, it may be less efficient and could be nearing the end of its lifespan. Modern air conditioners are more energy-efficient, and replacing your old system could result in saving on energy bills.

Second, frequent and costly repairs are another red flag. If you find yourself constantly calling for repairs, it might be more cost-effective to invest in a new unit.

Finally, if your AC system is struggling to maintain a consistent, comfortable temperature, it may be past its prime and in need of replacement. We can help you make an informed decision about whether to repair or replace your AC unit.

Our team of HVAC professionals will perform a thorough evaluation of your existing system, factoring in age, repair history, and current performance. If we recommend a replacement, we will help you select and install a new, energy-efficient model that suits your cooling needs and budget.

Save Energy, Save Money

Not only can you save on operating costs with a new air conditioning unit, but you can also feel better about reducing your carbon footprint and using less energy. When you consider how much we use our air conditioners here in Maryland, the savings that a more efficient unit offers quickly add up.

You may be aware that some homeowners opt to replace their furnace at the same time they get air conditioner replacement because these two home systems work closely in tandem. Replacing them both at the same time may benefit you, but it may not be necessary. Our HVAC technicians will explain the pros and cons to you.


  • Assess the Size of Your Home or Business: by matching the proper unit to the size of your home, we ensure that your home or business is successfully cooled without waste, dramatically reducing your energy costs.
  • Perform a Heat Load Calculation: by taking into account the number of windows, fireplaces, skylights, current insulation, height of ceilings, ductwork, and size of family, we can best anticipate the load of heat gain your system will have to combat.
  • Conduct a Duct Inspection: by measuring the size and length of your ductwork (as well as its current condition) we can ensure your new system will properly, and efficiently, deliver cool air throughout your home or business.
  • Consider Your Unique Family Needs: Children and adult allergies, pets, noise, remote temperature control, utility bill saving can all factor into the choice of a system that is right for your home.
  • Discuss Benefits and Features: once we’ve thoroughly assessed the needs and conditions of your home or business, one of our Comfort Advisors will provide their skilled opinion, as well as discuss the benefits and features of all available systems and how they will function in your home.
  • Offer Rebates and Discounts: Our Comfort Advisors are aware of all the latest cost-saving opportunities available from utility companies and manufacturers, on high-efficiency equipment and make sure you are able to benefit from available programs.
