"I've been hiring Tony from Cold Air Mechanical for about 10 years. First for my apartment management business when my on staff techs couldn't figure out the problem and then at my home. He's always very pleasant to work with and very knowledgeable. Where I've had other HVAC techs try to sell me unnecessary equipment for outrageous prices (thank you Private Equity), he's actually identified the problem and usually has the part in his van at a fair price. While I'm not HVAC certified, I know my way around and I'd definitely recommend Tony."

"Theo, the owner is great as an HVAC pro. We asked him to come out for the tune-up going into the summer season. He checked, very thoroughly, both our units. One was good to go, but the other one needed 6lbs of freon. Theo explained everything and showed us everything that he checked. He even tried to work with our home warranty company to see if they would cover the cost of repair/replacement, but they would not. Theo gave us our options and we asked him for his honest recommendation. He said a new unit. Ours is nearly 20 years old and has been repaired several times recently. We went with a new unit and he was able to install it within two days of us talking. He made sure the installation was smooth and with minimal interruptions. His thoroughness have us feeling better about our decision and trust in his judgement and professionalism. Very good HVAC pro and a good guy to do business with during these times."

"The tech was very knowledgeable and skillful. He had to install the new blower fan into the existing fan housing, but he took the existing blower assembly (fan, motor, electrical, and housing) out to his truck in inclement weather to do the work. I offered up my garage, but he said that he would be fine out in his truck. From start to finish it could not have been more than 40 minutes. The blower unit runs and sounds like a brand-new install. Very quiet. Prior to the repair the blower sounded like a freight train passing through the house. Very happy and the cost was reasonable."

Heating and Air Conditioning FAQs, answered by experts

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.
