"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

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.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the 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.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit.
