"My heating system wasn’t working properly, so I put the job at Angie’s list and Ray was the first one to call, very professional and he sent his tech (Isiah) right away and was able to remedy the issue in a timely manner. Very happy with the service with Ray’s HVAC and Isiah. Saving their contact details as my HVAC guy from now on."

"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."

"Sam and AJ are the best! Submitted a request on Angi yesterday afternoon, received an immediate call back saying they could be here within 2 hours to diagnose an issue with our central A/C air handler in our attic. AJ was here promptly, and immediately went to work systematically checking through each part of the system. Side note - it must have been 115 degrees in the attic while he was working, didn't seem to bother him at all! Within 2 hours, he had identified a failed motor, sourced the parts, and gotten me a very reasonable quote for replacement. Parts arrived the next day, when he and Sam came out to install, got the whole system back up and running normally, and cleaned up. They did the job for the price they quoted, in the time they quoted it, without trying to sell me an entire new A/C system.... can't tell you how much that's appreciated. First time customer, but will definitely be using them for our boiler service as well. Fantastic service. Could not be happier I found them."

Heating and Air Conditioning questions, answered by experts

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.
