"The person who handled my call was friendly and professional. She told me a technician would be at my house in 4 hours and called me when he was on his way. The technician was outstanding, on time, professional, friendly, and quickly diagnosed and fixed the problem...best of all, he didn't try to sell parts/service that I didn't need! Best experience with an HVAC company I've ever had."

"I called, not knowing what was wrong with my air conditioning. They actually gave me a few possibilities, over the phone, one of which turned out to be the Culprit. No charge for the advice, they could have easily rip me off. But didn't. They won't give u the run around, and tell you somethings wrong when it's actually not."

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

"This was the third time that I have used All American Appliance Service.  Scheduling was fast and easy.  The technician, John, was on-time, courteous and professional.  He quickly diagnosed the problem as a bad water inlet valve in our dishwasher, and had the parts on his truck to make the repair.  I would definitely recommend All American Appliance Service to other Angie's List members.

Heating and Air Conditioning FAQs, answered by experts

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected.
