- Doug V.

Ductless Mini-Split Maintenance in Arvada, CO 80005

“Ulises arrived right when he said he would, asked what was going on and then looked at the head that I said was the main problem. Quickly determined that it was the blower wheel that needed to be cleaned (shame on me, I knew it needed to be but did not think it was the root cause). Looked at two other heads to confirm they were working and said again it is likely the blower wheel not moving enough air. Seemed to be quite knowledgeable on the system overall. Must better service than the original installer when they came out last summer for the same issue (who did not even come inside to look at the head!). Earned my return business.”

- John H.

“We just had a 4-zone mini split / heat pump system installed along with a 200amp service change by the Kappler team. We were thoroughly impressed and delighted with the Kappler team through the whole process of our challenging project, from start to finish. Our initial site evaluation and assessment was very thorough and well planned out. We especially appreciated Kappler’s attention to detail, receptiveness to consider options, patience, and skillful oversight and support during the entire implementation phase. The Kappler team was exceptional and exceeded our already high expectations. Their teamwork consistently impressed us for the full 3 days on site, and was seamless, professional, highly competent, and effective in creating a well-built and perfectly functioning mini split system for our home. Moreover, the friendliness, cooperativeness and genuine helpfulness of each of Kappler team member was exceptional, and quickly won our trust and confidence. Kappler turned a potentially stressful, complex installation into a relatively calm, well organized, and very positive experience. We couldn’t imagine things running as smoothly and turning out so well as they did.

Air Handlers Replacement in Erie, CO 80516

“Aside from inflationary rising costs (the new blower motor costs $800!), I have always been pleased with Kappler Mechanical. Been with this home heating-A/C service company for nigh 15 years (in two different homes). While I trust every technician that has serviced my home(s), I have developed a special comfort with Ulysses (Uli). Uli is very professional, expert in his technical knowledge, and an extremely thorough (attention to details) technician. So I usually special request for Uli. Kappler Mechanical is a high-integrity, responsible AND responsive service maintenance company.
Funny how one develops a trust and comfort level with outstanding service providers like Kappler. I highly recommend Kappler to every home-owner.”

- Keith W.

Air Conditioner Repair in Westminster, CO 80030

“Wow, seriously stellar service with Josh’s visit this morning to see what’s going on with our AC unit. When you bring an expert in, it’s easy for miscommunications to happen… Josh was completely transparent, informative, and educated me about what he was finding and what the possible outcomes could be depending on what we find at the next step. While sometimes it’s nice to be hands off and just let the expert do their job, as a homeowner, I feel it’s important to understand how the equipment in my home works and what possible problems could occur given the current circumstances. Josh’s service, communicativeness, and general vibe tops any experience I’ve ever had when it comes to home repair services. Thank you Josh!”
