I WORKED WITH MIKE FOR APPLIANCES AND VLAD FOR HVAC AND THEY WERE EXCELLENT!!!! THEY EXPLAIN EVERYTHING EASY AND CLEAR SO THAT YOU UNDERSTAND WHATS GOING ON WITH THE PROBLEM. THANK YOU GUYS!!!







The installation team, including Eugene, was meticulous and respectful throughout the process. Julia was incredibly patient, answering every question we had and walking us through all the options from the various quotes we’d received. We didn’t choose the cheapest setup or the most expensive one; instead, we were able to select the exact make and model of the furnace, evaporator coil, and AC unit to match our needs and budget.
From dismantling the old system to installing new ductwork and cleaning up afterward, everything was handled efficiently and professionally. The workspace was spotless when they finished, and we couldn’t be happier with our new HVAC system.
Shop around and compare—what truly set JT Services apart for us was how Eugene and Julia communicated and treated us. Their professionalism and care made all the difference

Overall, the repair was successful, and the technician correctly diagnosed and fixed the issue. The replacement part arrived within the estimated timeframe, and once it was available, the repair was scheduled promptly. The technician was professional and explained the repair process clearly.
The reason I'm leaving 4 stars instead of 5 is the billing and communication.
The technician told me that my $60 diagnostic fee would be deducted from the total repair cost. The estimate I received prominently displayed a total of $323.61, which I naturally understood to be the total cost of the repair after that deduction. However, the final invoice showed that the actual total out-of-pocket cost was $383.61 because the $323.61 represented only the remaining balance after the previously paid $60 diagnostic fee.
The math is correct, but I believe the estimate is presented in a way that can easily confuse customers. I recommend asking them to clearly state your total out-of-pocket cost, including any diagnostic fees you've already paid, before approving the repair.
Communication during the parts wait could also have been more proactive. I had to follow up several times to get updates on the shipment status.
Overall, I'm satisfied with the quality of the repair itself, but I think the billing presentation and customer communication could be improved.

As far as home warranty went, he didn’t do cleaning, filter check, anything I would have had done by my own HVAC company for spring and fall maintenance.








the tech knew exactly what was wrong
very professional and personable. 10 stars







After talking with Matt at JT Appliance they were willing to send out a tech to assess the problem. Kevin quickly found the issue. They were willing to work with me and the company to acquire the part. After a couple of weeks Kevin came out and replaced the part and repaired the unit saving me a ton of money on replacement cost and shipping.
Thanks so much JT Appliance! I will definitely contact JT them again to address any other appliance repair needs that I might have!



We had a financial issue and they worked through it with us even very fair people to deal with overall.














Update:
Just had a second system replaced (the house has 2 systems). Very similar experience as last time.
He swiftly and confidently repaired our double oven. Not only were the upper and lower (baking) heating elements broken, but the computer board needed repair due to failed relays. It was removed, sent out for repair and reinstalled. Works perfectly.
Highly recommend this business and technician.
