"We were having issues with our fireplace. The tech came to our house and was very professional, and quick to find out what the issue was. The price was fair, and we are really happy with the service. Would definitely hire them again for any service related to our AC or our fireplace, highly recommended!"

"The quality of the work was great, it is the product I am not sure about. Just had the system put in last year and the mother board needed to be replaced. While it took longer than expected to receive the part, once received, it was replaced the next business day. The technicians were knowledgeable and efficient. They replaced the part and performed the inspection; and explained it all so I could understand what they did (they even replaced the air filter without my asking). I have used this company for over ten years and find their employees willing to help me keep my system running smoothly and efficiently. I highly recommend McCrea of VA for your HVAC needs."

"Quickly diagnosed the central air conditioning system, and gave an estimate on the cost of recharging the refrigerant in the compressor. The system is a 14 year old Carrier unit. Albert also included some sealant that may plug up the slow leak of refrigerant that occurs every 2 years or so. Albert also, showed me how to adjust the damper to control the flow of air to the second and third floors of the house. The other company that arrived wanted to charge me $5,000 to repair the system or close to $7,000 to replace the AC system with new. I intend to call upon Magna Tech Temp Air, Inc when I'm ready to purchase a new HVAC system. Thanks again for taking the time to listen to my concerns. Well done!!!"

"AC Tech Aaron was highly knowledgeable, amicable and was able to solve an issue that previously caused ARS to replace a newly installed HVC system with another new system, however, Aaron was the one to solve the ongoing issue I had with both current and previous systems. The issue was, the AC simply was not efficient enough to cool my house, reason, the air filters were severely clogged. Solution: Aaron applied a commercial degreaser, then washed both filters, this dissolved an accumulation of over 10 years worth of gunk and soot like dirt. Thanks to Aaron, my AC now is finally running to its full capacity without compromising its efficiency or causing it to overheat or worse, break down. I would recommend ARS to at a minimum inspect and equally clean all AC filters as that would go a long way towards resulting in a far better AC/HVC performance with better efficiency. Thank you Aaron. Joseph"

Air Conditioning questions, answered by experts

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.

Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.
