They have provided twice yearly inspection and any needed service for our heating and a/c units for many years. Have always been very happy with all interactions. Service: Ductless heating & A/C services
The winter inspection and maintenance was very good. Along with that excellent tips on when oil is ordered and keeping a consistent temperature. Ways in which this maintenance helped to slow the use of oil during the winter. Services: A/C filter replacement, Heating system maintenance
Just recently,1/13/2023, had our heat pump and electric heating system replaced. The only piece that was good was the humidifier. The installers showed up early and never stopped until the job was completed. It took approx 5 hours to do the job. The installers were very friendly and professional. Kudos to your team for pushing through in getting this completed with such lousy weather. Corcoran and Harnist is my go to HVAC company. Great job all around Service: Installation
