Renat from AVANT HVAC came on a Sunday to fix our heating issue. I had broken the heating while self installing a smart thermostat. He communicated the time of arrival and was here exactly on time. He was very knowledgeable on the HVAC and quickly diagnosed the issue to be relating to the thermostat. My old thermostat had fried due to my failed attempt at installing a smart Thermostat. Even though he hadn't worked with my specific brand of smart thermostat, he quickly figured out the connections and installed it. I would recommend AVANT HVAC for the professionalism of the technician who was was very fast in diagnosing and fixing the issue and also for their availability on weekends when none were available.

Excellent experience overall - we passed HERS test and city inspection just now. The city inspector said they did solid work. AVANT installed a new A/C condenser (Carrier slim 14 SEER) and replaced all ducts in a two-story house (with flex ducts), and provided permits and HERS tester. I got at least five bids from different contractors in the area and theirs was among the top ones. The work took two days: they worked whole day pretty late on the first day, so we avoided overrun to the third day, and finished about 3pm on the second day. The crew was respectful and pleasant, and cleaned everything up inside and out. AVANT offered 3y warranty on labor. Oleg was my contact, he was very responsive from beginning to end, everything he said always checked out, and I detected no BS (no unnecessary upsells, no convincing not to get a permit, no bugging with phone calls before I made my choice, etc - being a women who hires many contractors I've heard my share). Great experience overall, wold recommend and would re-hire.

We had a great experience with Avant HVAC team. I needed a new AC and furnace to be installed. Oleg is very responsive, reasonably priced and very professional. He and his team completed the project efficiently and with great quality. Highly recommended.

Oleg from Avant HVAC was the consumate Pro working tirelessly to determine my furnace problem...when it was finally determined that the repairs and parts necessary to get my old furnace functioning again were proportionate to the cost of a new furnace, Oleg provided me with all of my options and time to mull over my final decision to replace furnace with a new unit...Oleg and Team represent old fashioned "Customer Service" with quality work at it's finest, something we all have been missing of late. I would highly recommend and his team for any of your HVAC needs!
