Back to 5 Stars
I have used Service Experts 10+ years. They were great, then not so great for a few years, and recently back to being outstanding. In the not so great years I tried other companies and found them either unreliable, over-priced, or inexperienced. I found myself continually coming back to Service Experts. Most recently, Marcin has provided excellent service, reliability, and skilled labor. As a member and a senior, Service Experts provides valuable pricing discounts. Also, if you have a boiler system, I recommend SE. Back to 5 stars!
Timely response
Timely response. Technician Nealon Smith was competent, efficient, and informative.
Ronaldo & Kasey did a wonderful job.
Ronaldo & Kasey did a wonderful job. They were very thorough and professional and most polite.
Very satisfied with expert service
Made a request to Service Experts for HVAC system inspection and system repair as the blower was making a rubbing sound on Friday for inspection the following Monday. Got nervous about the noise and made a second request to move the appointment up to the next day, Saturday. Paul showed up on time and made the repair very quickly. We were very satisfied with the response and the expert service that the technician, Paul, provided. Great job, thanks!
Nealon went beyond expectations
Nealon went beyond expectations in maintaining our HVAC system. He identified a water leak that will enable us to fix the leak early, before there is water damage.

Good service
Good service. Jerrod was able to diagnose our lack of heat problem and replaced the condensation line on our furnace and replaced the drain unit. Never had this problem before, but the furnace is 8 years old next month. Disappointed in the cost, but I'm sure other companies would charge about the same.
Marcin is the best technician
Marcin is the best technician I have had in the 34 years I have had Service Experts. He explained everything in great detail, and his service was very professional and prompt.
