"Porterhouse Heating and Cooling was very professional and knowledgeable on the service provided. I used them to install my air conditioner unit. Eventhough, the unit was not my issue, they still came out and was able to find the issue and fix it. They were friendly, professional, and reasonably priced. I will definitely use again for any of my HVAC concerns."

"My husband carefully spelled out his name and our address over the phone, but the office still got both wrong. But besides that, the service tech arrived early after calling us in advance (much appreciated), found that the drain trap was plugged which prevented the unit from moving into the second stage of the heating process, and he cleared it. We're confident that the problem was fixed, and we're pleased with the work he had done. Jim was personable, knowledgeable, and helpful. But for the 20 minutes he was here, and the limited scope of the work that we could see that he had done, we feel that the charge for our drain line flush of $288 was pretty high. We didn't get quotes from other HVAC companies, and we trusted AWE based on Angie's List's reviews, but on reflection, it seems pricey to us. We will nevertheless call them for annual servicing because they are reliable."

Heating and Air Conditioning FAQs, answered by experts

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.

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.
