"Duke did a great job at a fair price. We needed AC and decided to replace our old furnace at the same time. In addition Duke wrapped with insulating bubble wrap our old ducts that were exposed. He tied the drip line into our existing downspout in a neat fashion. I'd highly recommend him (he's a fellow submarine vet too!!)."

"My mother's house had air conditioning that was improperly installed so it wasn't really cooling anything but the bill was still running pretty high. So basically there was a leak in the duct. I would use them again for air conditioning."

"They responded very quick and they found the problem. The part required was expensive and due to the age of the furnace I decided to purchase a new high efficent furnace. The price was fair and they installed it the next morning."

"Great team. While the job is messy as they have to work under your house. Aire Serv was great to work with. We needed new ducts and boots and my house is now moving air better than it has in twenty years. Highly recommend Aire Serv."

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

"I discovered a problem with my upstairs air conditioning unit after business hours on a Friday night. At that time I completed and submitted a request for service on Home Advisor on line. Comfort a Energy contacted me via telephone early the following Saturday morning. We scheduled an appointment for them to come out and diagnose my issue. Their repairman showed up promptly and diagnosed the issue and provided a cost for repair. I had them repair my air conditioner and I’m happy with the result."

Air Conditioning questions, answered by experts

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.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.
