"The men were on time, knew what was needed and cleaned up after. They were a great team. I spoke with the manager who helped me decide what would be best for my situation. I recommend them to everyone for insulation of their attics. Thank you Mr. Brock. It was a pleasure."

"Newton Williams was amazing and knows everything about ac, heating and electrical and more. I am so relieved. Every year someone comes to fix something. He fixed it all and cleaned the outside unit perfectly. Nobody to the time to explain or do the work he did. He let me know what it should be like and he fixed it. The air smells clean and colder than it used to get. I will never trust anyone else."

"Mr. Guss is very professional. He provided excellent technical information on my A/C replacement and very competitive pricing. He helped properly size the system. I was going to buy something larger than I needed and he explained that it wasn't necessary. I've had it installed for a while now and it has been exactly as he said it would be. I've hired him for another unit on my home since, and he's done work for a couple of friends. We've all been very happy with his work. Highly Recommend!"

Heating and Air Conditioning FAQs, answered by experts

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

Yes, through thorough cleaning and inspection, optimizing functionality, and reducing energy use.

Many factors affect how much adding air conditioning will cost you, from the size of your home to the size, type, brand, and installation specifics of the system itself. Chances are, a new central air conditioning system for a 2,000-square-foot house will cost somewhere between $3,900 and $7,900 to install, with an average around $6,000. 

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

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.
