"I am a attorney in Nutley, New Jersey. We had no air conditioning on the second floor of our commercial building yesterday. After our regular HVAC maintenance company claimed to be too busy, we researched an alternate and found excellent reviews for Challenger. Access to our roof AC system is a bit tricky. It was no problem for Jorge of Challenger. He easily navigated the approach and the scuttle. The AC was in tiptop share in less than an hour, portal to portal. The price charged was fair and the work was clean and professional. Challenger has a "can do" attitude and approach to HVAC. Thank you Jorge for an excellent job. Based on our experience, I am very pleased to refer this company to others."

"We recently had the pleasure of hiring Dawson Mechanical to have a new Navien tankless water heater installed. This was a little more than a straightforward job since the water heater was being relocated from a utility closet to the garage which was about 20 feet away. From the time I made the first call to Dawson, I had a good feeling about this company. Dave came over within a few days on a Saturday to look the job over and give me an estimate. He is very knowledgeable and took the time to answer any questions we had. When the day came for the installation, a crew of 3 workmen arrived around 9:00 AM and did not stop until the job was finished around 5:00 PM. They did an excellent job, were very good about keeping everything clean and neat, and the workmanship was top notch. In short, we were very happy with everything and would not hesitate to use Dawson for our future plumbing/HVAC needs."

Heating and Air Conditioning questions, answered by experts

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

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.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.
