AC Install Reviews….

“If you need a new system and have an emergency– look no further!  This company is the BEST!  I just want to say that I do NOT say that very often, as I have been ripped off by contractors in the past.  I can’t begin to express my gratitude for everyone who turned my nightmare into a “happy day”. I will certainly call them in the future for additional work.”

Yelp! 5 star rating

“Great Service! When my air-conditioning failed after our recent heat wave, I had the most wonderful experience with perfect star heating and air conditioning services.  I was treated with kindness and great respect and have had the best service experience for a major home expenditure of my lifetime. Thanks, guys!!!'”

Ready for help with a repair or project?

Our Perfect Replacement & Installation Guarantee


Perfect Comfort Guarantee
We guarantee that when properly designed systems are installed, maintained, and operated in accordance with the manufacture’s operating and maintenance manuals, the system will perform as we have stated and agreed upon. If your desired comfort is not achieved, we will make any modifications or repairs necessary to reach the desired temperature at no charge to you for a period of one-year.

“No Duds” Guarantee
If the compressor in your air conditioner fails during the first five years of ownership, or the heat exchanger in your furnace cracks during the first ten years of ownership, we will remove the entire unit, rather than the component and install a complete new one. If you’ve ever purchased a ‘dud’ before, you’ll truly appreciate our commitment to your long-term satisfaction.

Perfect Price Guarantee
Anyone can make something cheaper by cutting corners and pricing it for less. So, it’s important to know what is and is not included in any heating and cooling system you choose for your home. Our price guarantee is our promise to you that you cannot find a comparable installation for
less … or we’ll pay you $75.00 over the difference. All we ask is that it is a current published  ‘apples-to-apples’ comparison.

Perfect Workmanship Guarantee
Our installation technicians are the best in skill, attitude and workmanship. They’ll care for your home and complete the job with speed and precision. They wear floor savers, clean up when they are finished and take personal responsibility for your satisfaction. They are polite and courteous and will not smoke or swear in your home. If, when they have finished in your home, they have not performed in accordance with these high standards, we’ll refund whatever amount of the purchase price you feel to be fair.

24-Hour Fix It Guarantee
We are a full-service company and have a staff of qualified service technicians that are there to serve you in the event your system is having a problem. Our guarantee to you, is that when we arrive, we will have your system up and running within 24-hours of our arrival or we will give you $250.00 to compensate you for your inconvenience.
