"had such a great experience with HighPoint HVAC! The entire process was seamless and incredibly easy from start to finish. I was able to schedule an appointment right away, and the team arrived exactly on time. They were professional, friendly, and took the time to explain everything clearly. After finishing the job, they left the space spotless; you’d never know any work had been done. Their quality of service and attention to detail really stood out, and the pricing was very fair. I’d highly recommend this company to anyone looking for reliable, high-quality HVAC service"

"A-Moonlight provided timely and professional service. They were able to diagnose issues with my A/C and furnace quickly and explained the issue and their proposed solutions. Brent made me aware of my options for repair and what services were necessary and what was not. They were able to install the parts I purchased and service my furnace and A/C within a few hours. They got everything working in one trip and charged about 1/6th of what a competitor was asking. I would highly recommend A-Moonlight for any residential HVAC needs and I will be hiring them in the future should I need any other HVAC services."

"I called AT Mechanical to service my air conditioner. And I've got to say, it's like new! My AC used to not be able to keep up with the temp in the house. Now it easily does! Please give them a call if your AC isn't keeping up on hot days! I highly recommend using them to service your AC or furnace."

Heating and Air Conditioning questions, answered by experts

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

If you’re looking for an energy-efficient heating and cooling system to heat a compact to average-sized home, then a ductless system is absolutely worth considering. The installation is less hassle when compared to a ducted heat pump system, and because your electricity bills should drop, it’s an excellent long-term investment.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.
