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…
Reached out to Holtkamp early in the morning. They responded quickly and Hunter arrived approximately an hour after my initial call. He had everything needed on hand, explained the repair process and finished the job in under an hour. This is my first experience using Holtkamp. I would recommend and will use again if a need…
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.
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 fir arrival (as opposed to 4 hours with other services); and call you when they're on their way.
We have utilized Holtkamp for years, continuing our service when we purchased a new home. Eduardo was very knowledgeable and respectful when he came by today to service our units. We appreciate the quality of service technicians at Holtkamp!
