"Duke did a great job at a fair price. We needed AC and decided to replace our old furnace at the same time. In addition Duke wrapped with insulating bubble wrap our old ducts that were exposed. He tied the drip line into our existing downspout in a neat fashion. I'd highly recommend him (he's a fellow submarine vet too!!)."

"I discovered a problem with my upstairs air conditioning unit after business hours on a Friday night. At that time I completed and submitted a request for service on Home Advisor on line. Comfort a Energy contacted me via telephone early the following Saturday morning. We scheduled an appointment for them to come out and diagnose my issue. Their repairman showed up promptly and diagnosed the issue and provided a cost for repair. I had them repair my air conditioner and I’m happy with the result."

"I recently used Chill Heating & Cooling for my air conditioner maintenance, and I am extremely satisfied! The technicians arrived on time, performed a full diagnostic, cleaning, and refrigerant refill. They worked efficiently and professionally, explaining everything clearly about proper system care. After the service, my AC runs much better?cools the room faster and operates quietly. Excellent service, knowledgeable technicians, and fair pricing! I will definitely use their services again and highly recommend them to anyone looking for reliable AC maintenance."

Air Conditioning questions, answered by experts

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it. 

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.
