"We were switching over from oil to propane heat. It was a pleasant experience from the time we first met Jason who was very knowledgeable and a joy to talk to. The installers were very professional and did a great job. Aire Serve worked seamlessly with Curtis oil and job was completed in 1 day. We are warm happy campers and would definitely recommend Aire Serve and Curtis Oil & Propane."

"Mike was friendly and efficient. He hooked up our gas stove (and had warned us when we first called to make sure we had the proper electrical for it...which we didn't and arranged thanks to him) . He also took time to check out another job we might do in the future. Would definitely work with him again."

Air Conditioning questions, answered by experts

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.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

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. 

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.
