"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

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

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.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.
