My furnace went out during the heavy snow period this year. Scrambling for someone to come repair it was like looking for a needle in a haystack. Bartels was able to get someone out the same day! Nick and Jim (the two technicians that completed our service) diagnosed a faulty control board (my furnace is 13yrs old and out of warranty), were able to quote the part and labor before ordering it, got it on order for me, picked it up from the supplier, and came back to complete the repair the same day. They were clean, polite, and knowledgeable. I spoke with Paul on the phone to coordinate their visit and get regular updates if anything changed while they weren't at my home. He was similarly competent, kind, and polite.Last of all, as a homeowner, I think we can agree that none of that would have mattered if the price they gave me was unreasonably high. This wasn't the case. I felt that the cost of the repair was very fair for the work performed.I plan on using them again for my future HVAC needs.Thank you for your services, Bartels team. I really appreciate it.
