"Ali came over to our home when we called with a concern of the air flow in our central air conditioning system. He checked the return, the air flow, the temperature at all of the vents, and the entire system. It had more to do with the age of the system and gave us suggestions on how a different filter could increase the air flow. He did all of this and refused to take any money for his time. He is a true honest professional and someone that we would recommend to everyone."

"Chris was fantastic! He was on time, friendly, and got the job done right. Our AC was not cooling at all, and by the time he left everything was working great again. Professional, knowledgeable, and easy to work with. I highly recommend Chris for any air conditioning needs!"

"Joe and his team were outstanding! From the moment I met Joe he was friendly, knowledgeable and made sure to answer all of my questions. He sized up the project and explained in simple terms how the process would work: The price was excellent for a new whole house Ductless Mini Split AC System . When they showed up for the install they walked through how it would be done and explained it in simple terms. They were all neat and clean as the did the job and wore their masks the entire time over the two day job. I highly recommend Joe and his team and will absolutely use them again for all of my HVAC needs."

"You will not be disappointed with Kyle and company. Replaced old AC unit with a new AC/heat pump system. After the deposit Kyle didn't ask for any money until the job was DONE! AND...while other companies jacked up the price for a heat pump system, Kyle was on the nose. You won't be disappointed at all!!!!"

"Excellent.
Very professional and honest business.
Howard cleaned 2 separate air conditioning zones and also the dryer vent.
He returned about a month later when we had an unrelated air conditioning issue and helped us out at no charge.
Would very highly recommend.

"Jonathan Moya is the owner of the company. My wife and i decided to finish our basement as an extended living space. We asked for three estimates for ac and heating, and mini split systems were recommended. Jonathan Moya and comfort duct systems, was the only company that explained the deficiencies in such a system as compared to central ac and heating. He explained the pros and cons of each system- In fact, the mini split would have cost us more money! My overall experience has been nothing but positive. I found Jonathan to be honest, knowledgeable, and extremely proficient and reasonable. I was confident from the moment that I met him, and after he completed the installation of my central AC unit for a 2000 square foot basement, it confirmed my initial instincts- Jonathan is simply the best at what he does. Please believe me, because I have worked with countless HVAC so called professionals over the years, and not one of them has impressed me the way Jonathan and his company has- I will never hire another HVAC company again- these are the guys you want in your home. I give Jonathan Moya and his crew my highest recommendation. You will not be disappointed! Sam M. From Oyster Bay , NY"

"We were desperate to find someone to repair our central air conditioning unit. We were not able to move into the house and everyone that we called was not able to accommodate us because of the recent heat wave. All Weather was able to get a technician to us within 2 days. Nuri was amazing and showed my husband how everything worked and what repairs needed to be done. By the time he left, we had a cool house and were able to set up our movers. Thanks to Angie’s list, I found a reputable company that was reliable and efficient. We can rest easy! Thank you!!!"

Air Conditioning questions, answered by experts

In most cases, homeowners insurance will cover an AC replacement if it was damaged due to a covered peril—such as theft, fire, or storms. So, if your air conditioner needs replacing due to regular wear and tear, your insurance company probably won’t pay for a new one. However, home warranties often cover HVAC repairs and replacements.

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.

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

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.
