I recently contracted with Dave Katt of Keystone Heating and AC to upgrade the HVAC systems in our 20 year old home. I have used Keystone's maintenance for many years to keep the old systems... more

The Katt family has been in the HVAC business for many years. They know this stuff inside and out whether you have an old fashioned oil burner, an old gas conversion, or the newest high-tech unit on the market. The service is second to none. Fast, courteous, friendly, and honest. They knew every detail of my system because they installed it for the previous owner of this house. I've been here only 3 years but have know the Katt family since we were kids. when I saw their sticker on the furnace, I knew the previous owner had made the right choice for his HVAC company. Then when I called for service, Dave knew right away without hesitation exactly what kind of system I had. Really, it didn't even seem as though he had time to pull it up on a computer. I think he had the information off the top of his head! I gave a him few details and he had a very good idea what the problem was right away and sent a man out with all of the correct parts on the first trip. now THAT"S efficiency! I highly recommend Keystone for all of your HVAC service and for new installations as well. You simply can't go wrong with Keystone.

The installation of my furnace yesterday was fast and efficient. They showed up on time and showed me how to program my thermostat for my schedule. Thank you

Excellent, efficient service; high quality products - we have recommended this company and will continue to do so.

Have used Keystone for years. Very knowledgeable professional service techs, on time - explain what issues they are seeing. They don't try to gouge you. I suggest the annual service agreement. Well worth the peace of mind.

Very professional. Crew of 3 guys were on time, and got the job done quickly. Very courteous and friendly. They took the time to explain what they were doing. They did not leave until the job was 100% complete. They were able to trouble shoot an existing problem to make the entire system fully operational. Cleaned up after themselves by taking out the old furnace and scrap out. Thank you very much, Gloria and Jr. Bernal

Great company! Have been a customer for years. Would highly recommend! Ken always does a very thorough job! I wish there were more companies like this, that you can trust to do a good job without ripping you off.

On time, courteous, knowledgeable, professional repair. will use again.

Our Furnace went out when it was extreamly cold out. Keystone responded very promptly and had the parts on the truck to get our furnace running. Even though they did not install the furnace the warranteed the part for us and took care of the problem.
