Our Customer Reviews

Glenda L
It’s wonderful to have an experienced heating and air technician like Matthew Holtkamp! Our heat went out on Sunday with the polar vortex sweeping in. We called and Matthew came out that day and fixed us right up. Can you imagine the owner of the company coming out on a Sunday? We have used this company for about 20 years and would not consider anyone else. So reliable and trustworthy in every way!
Fabiola C
Great technician with good knowledge of the system. Very respectful and courteous. I have been using this company for the past 6 years and I must say their standard has never changed. Thank you, Eddie and Holtkamp for keeping our family safe throughout the seasons.

Every service person from Holtkamp has been professional, knowledgeable, and nice. When we had a problem in the past, they came promptly. They give a 2-hour window for arrival (as opposed to 4 hours with other services) and call you when they're on their way.

I’ve switched my servicing and repairs to Holtkamp HVAC and they have been amazing to work with. Always on time, fair with pricing, and the staff there is extremely polite and professional. Highly recommend them if you need your system worked on or replaced.
