"Had a great experience with Kamal. He is helpful, knowledgable and very dependable. We had a crisis with our old hvac system and were freezing. Kamal was the only one who came within 2 hours on a holiday while others were available only the next day or later. Most were closed that day. I got a great deal on the new SEER16 hvac and have been happy with it. My electric bill has cut down to almost half. Also he offers 2 years of his company’s warranty in addition to the manufacturers 10 year warranty. Highly recommend Kamal and will be using him for future."

"Needed a complete service on my furnace and A/C system prior to putting my house on the market in a few weeks. Magna Tech Temp Air did a terrific job at a very reasonable price. Showed up on time and got the job done right. Great customer service, good communication, overall great experience. Wore shoe covers to protect my flooring. Shout out to Albert, he even went above and beyond to help me with opening the indoor valves on my outside water spigots because I couldn’t reach them at 9 months pregnant. Definitely recommend this company. I feel confident knowing that when the home inspector visits my house pre-sale, my HVAC system will pass with flying colors."

"Virginia Heating and Air responded to my request for HVAC repair immediately and they arrived the next morning during the scheduled one hour window. Mark and Steve were great, they listened and were able to quickly doagnose and repair my cooling system issues, all the while educating me on how my system operated and how to keep it running efficiently. They did a full system inspection, a chemical cleaning of my outside unit, replaced a failed capacitor, recharged the freeon, and adjusted dampers for maximum efficiency. Price seemed fair for the work completed, which was completed in two hours."

Heating and Air Conditioning questions, answered by experts

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

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.
