I was a customer of Evans Heating & Air for ~8 years, but after recent failures won't continue with their service. My home was built new in 2012, and was under warranty for HVAC services the first few years with the contractor used by the home builder. I began working w/Evans Heating & Air in 2015. From 2015-2022, Evans did semi-annual checks on my heat pump + air handler per my annual service contracts with them, except for 2019. Until 2022 Evans never noted any system problems, and my total service plan cost before 2022 was ~$1,100. In March 2022 Evans performed my spring service and indicated no system problems. In August 2022 I scheduled a service call when my heat pump did not properly cool my home. The technician said my heat pump was low on refrigerant, and charged me accordingly (~$300). Of note, Evans did not diagnose any other system issues in August 2022. In November 2022 Evans Heating and Air performed my fall service (per my paid contract), and again indicated no system problems. Yet, in December 2022 I paid an electric utility bill of $333, a level rarely seen in >10 years at this home. I spoke with Rappahannock Electric Cooperative (utility provider), who noted my electric usage in December 2022 was ~30% higher than December 2021, yet the December 2022 temperatures were not 30% colder. REC said something was likely wrong with my HVAC system, so I scheduled yet another emergency call with Evans Heating and Air on 12/27/2022. On 12/27/2022 Evans again said there were no system problems, and it took a subsequent call from REC to Evans to have a more senior technician come to my home. On 01/06/2023 Evans Heating and Air finally diagnosed a coil leak in my air handler, and quoted a repair cost of ~$3,500 (service call on 01/06/2023 cost me $149). So, Evans came to my home on 03/12, 08/05, 11/11, and 12/27 in 2022, and on these 4 occasions failed to diagnose the real problem. And, had Evans been cleaning the coils on my air handler via semi-annual checks since 2015, this failure could have been averted before winter 2022. I have neighbors with homes and HVAC systems older than mine, who have never had HVAC problems. Yet, I paid for annual maintenance with Evans Heating & Air since 2015, and likely only got flashlight checks from them. And, my heating bill for January 2023 was $503.43. I have since had a new HVAC system installed by another HVAC company, and I will work with them going forward. Evans HVAC failed to do their due diligence. I will not recommend them to anyone!
