Top notch. If you dont call them first, then you called the wrong place. Best prices, equipment and great service. John fixed my (very old heater) a few years ago. This time his team installed a new heater and air conditioning unit. Top of the line Rheem. I couldnt be more satisfied.

Install was seamless and very professional from start to finish. Excellent price. I highly recommend.

John was terrific from start to finish. He answered his phone right away and was able to fit us in the same day our furnace went out. This was key for us since we work from home, and it was a cold and snowy day! John came when he said he would and called me when he was 4 minutes away from the house. Once here, he very quickly assessed the problem and then offered workable solutions to our very old furnace. John’s pricing was very reasonable and fair, he clearly knows his stuff, and he was a straight shooter to deal with. If you’ve got issues, call Allegiance - they will get the job done well and treat you right!

I recommend this company highly!! Great service, fair pricing. They know their stuff and are sympathetic to your belongings. Plus, they’ll text you with a precise arrival time.

John is professional, if running behind gives a call well before appt. We have used him for two years...for air conditioner and furnace and are very happy with service.

Edward Tongson is an excellent repair man. Great service and impeccable work!

John and his team are the absolute best. Alligiance heating and cooling is the ONLY company we will ever use.
