Just used John for the first time when my furnace stopped working. John was on time, friendly, knowledgeable, and was able to find my issue and repaired with parts on hand to save me some extra money. I will definitely be using him in the future! Thanks John!

We have been using and recommending Mavec since we first needed him after the tornado in 2017. John has always replied back to us promptly and fixed our issues in a timely manner. He is definitely our first call when heating or AC disaster strikes.

Called John Mavec this morning when we discovered our furnace had stopped running and the temperature in the house was dropping quickly with the freezing temperatures outside. First time customer and never expected such fast service! Within the hour, John arrived and diagnosed the problem! Very grateful to him for his great service! We will certainly keep his number on the refrigerator for future reference! Thanks John!! ☺️

John of Mavec Heating & A/C clearly earned & deserves every 5 star review he received. Thank you to the friend who referred, called John on Sunday for no heat. He would have come then but we sched for next day 9 a.m. He diagnosed quickly to find part not in stock at local supplier. He then escalated an immediate UPS shipment of the part from out of state, emphasizing his customer is without heat. He was here next afternoon with part in hand and had me up and running in no time. Thanks John, for the genuine concern you provided, and your expertise. You will have my continual future business and will absolutely recommend your company with no hesitation to others.
