"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."

"No 1 Cleaners were very professional and did a good job of cleaning our air conditioning ducts and vents. Carlos was knowledgable and did a through job. However, there was one thing that we did not like. While angi said that the initial quotation was FREE, No Cleaners said that if they came to provide a quote and we decide not to proceed with the work, we needed to pay $99 as fee for inspection. This was a bit disturbing as others did not charge for the visit and initial quote. I would recommend No 1 Cleaners as they were were professional and executed very well."

"ABCastello HVAC removed old A/C inside and outside units which were 25 years old from my 2700 sq feet 2 store colonial brick face house. Old units were replaced with new and more efficient units - TRANE 4 ton two stage SEER 17+ ECONET (condenser model RA-1748-AJ2CB, air handler model RH-2T-4821-MEACJA and communicating module Econet STAT model RETS-T601-SYS). Excellent work quality! Fast response! Very reasonable price quote for 10 years parts warranty and 5 years labor and service warranty! Honest and hard working person! All work was done in a couple of days (including old unit removal)! I am very happy and a very satisfied customer of his service for life!!! A+++++"

"We searched for a long time for a company to replace a current central A/C which was not particularly old, but the handler up in the attic was nearing the end of life so we had to replace the whole system. Speer seemed most knowledgeable, offered a product we were comfortable with (Amana) and were also professional and prompt. Of note we had a troublesome smart thermostat which required that they return multiple times to address - they did not consider the job done until this was fully operational. Overall we were very pleased, but the summer will tell!"

"The HVAC tech Jay was everything a homeowner could wish for in a contractor. He called 30 minutes before he was scheduled to arrive to say he was on the way, he was on time, friendly as can be & extremely knowledgeable, hard working & honest. He tried everything he could think of to repair the condenser before telling us it needed to be replaced. He didnâ t do what others would and just give us a price, he gave us options as far as equipment was concerned & the different price points. The folks at AAA HVAC went above and beyond with our system. What started out as a simple Condenser replacement turned out to be needing an entirely new HVAC system because the old system was completely mismatched & undersized for the size of the house & condenser we have, causing all kinds of problems. Including our original condenser dying in under 5 years. Long story shorter, it was an unexpected financial hit and they not only inspected, quoted & replaced everything within a day, they worked with me on financing. Jay even returned the very next day to fill out the invoice with all model & serial numbers that was requested by the manufacturers for any future warranty repairs, just registering the equipment on line was not good enough. I would without a secondâ s hesitation recommend AAA HVAC & Jay. I look forward to working with them on all our Future HVAC needs."

Heating and Air Conditioning questions, answered by experts

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

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.
