Hear From Our Past Customers

Integrity, honesty, and great service! “I generally have a service call for my furnace every year with your tech Ron Gallardo. I ask for him specifically – he explains everything thoroughly, never speaks down to someone like me who doesn’t know the inner workings of her furnace. Your company stands far and above in customer…

Good judgment, creative thinking and initiative “Pasterkamp Please accept my sincere appreciation for attending to our problem boiler under unusual circumstances. We travel for business and are only home every other weekend. We specifically wish to compliment Mark, the technician who fixed our boiler. I forgot to forward our phone, so Mark had no way…

Prompt Repair and Follow Up “Thank you for prompt repair of my furnace when I had no heat. Also I appreciate the follow up service that was needed.”

Great teachers! Pasterkamp people are wonderful. Great teachers as well as installers. So far the Lennox furnace is very quiet and provides much more even heat which is just what I was looking for! I’m anxious to try out the AC, and I’m sure it will be just as great. Thank you for a great…

Expertise, perseverance, and value… “Dear Dirk, Needed to let you know how much we appreciate your patience and perseverance to solve our air conditioner issue.

Nice, Fair, and Quick “Thank you for taking care of me today. Marc was very nice, fair, and quick. He knew just what to do.”

Our furnace recently died during the coldest time of the season. We called Pasterkamp after their closing time, left a message, and received a call back quite quickly. Ken Pasterkamp arrived at our home and had the current furnace working enough to make it through the night. The following day he was here again to install the new furnace and had it up and running in record time.

So, uh it's December 23rd, 1:30pm, -2 outside, and my daughter noticed cold blowing out of our furnace vents.  I call Pasterkamp first:  they're having their holiday party ... but, they'll send someone right over.  In under an hour Jesse shows up, total professional, finds and diagnoses the problem, has the part, repairs it in short order, and my family has heat for the holidays.


— Charles M
We've worked with Pasterkamp twice now. The first time was for our boiler. We thought we'd need a new boiler, but the guy (who came immediately at the end of the day!) really knew what he was doing and changed a small part. This was two years ago and still going strong. More recently, they came right over and fixed or AC. Very prompt service, courteous and knowledgeable employees, reasonable prices. Strongly recommended!
