I have Keeprite AC unit 9 years old had Bob fix the internal coil of my unit great service and very friendly and reasonably price he new what he was doing and before Celsius I called Enercare the guy quoted me 400 to remove the Freon to see what is wrong with it then another 1500 to 2100 to fix. Bob came over on Monday and then Tuesday took him 2 hours to fix and add Freon and the unit is working amazing. Thank you to Shirley great customer service, do I recommend 10 star’s.

Very bad people to deal with. Bob the owner is a liar and crook. Never have I encounter a small business such poor business ethics. STAY AWAY from this company. My heating bill doubled because of their work. They lie and ignore you when you have a complaint. BAD BAD BAD!

We are happy with their services. Their technicians are very knowledgable and they fixed our furnace the same day! Price is reasonable so we can always rely on them if we have any question or issue. Highly recommend them.
