"I had a great experience from start to finish with this company. They were able to install my new AC unit quickly, which I was thankful for, considering how hot it has been. Throughout the entire process, they were transparent with their pricing, explained everything clearly, and never made me feel pressured. Dylan and Tristan were incredibly knowledgeable, professional, respectful, and kind. They took the time to answer all of my questions and made sure I understood what was being installed and why. I was honestly pretty stressed about having to replace my AC unit, but they made the entire experience easy and worry-free. I would absolutely recommend this company to anyone looking for honest, reliable HVAC service. Their customer service and quality of work exceeded my expectations, and I couldn't be happier with the experience."

Heating and Air Conditioning questions, 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.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill.
