I had been putting off a new system for years and finally pulled the trigger. Through a friends recommendation I called Rick. Rick came to my house and explained all that I should be doing in an honest manner. He gave me a price for the complete system and never once had to change his price. I got top of the line service and products and my system runs so well my kids have to tell me to turn it off because I like it cold. Great relationship with the owner Rick and his crew that was clean and always on time.I give them a 10+Thanks Rick

Sinclair AC is awesome and they are now my go to AC company. I contacted them when my AC when out during an awful heatwave and they were able to get a technician out to my home same day. The office staff was super friendly, professional and efficient. When the technician arrived he was also friendly, professional and knew what he was doing. He quickly identified the problem, had the part in his vehicle and repaired my AC in less than an hour. The price was great. Thank you Sinclair AC! I give you my highest recommendation!

A SEER rating, or Seasonal Energy Efficiency Ratio, is a measurement used to gauge how energy-efficient an air conditioning unit is. When you’re considering an AC install, the SEER rating tells you how much cooling output you get per unit of energy consumed. In simple terms, a higher SEER rating means that the AC unit is more efficient, which can lead to lower electricity bills.

Starting from January 1, 2023, new AC installs must have a minimum SEER of 15. A 16 SEER unit is more energy-efficient than a 14 SEER. This means it cools the same area but uses less electricity, resulting in lower energy bills. While a 16 SEER unit may cost more upfront, it can offer long-term savings.
