Had issues with Furnace called first thing in am had crew out by afternoon to assess the issues, furnace was bad, had salesperson out that night, which was a Friday, Gave fair quote had new furnace installed the next Wednesday. … Technicians were very pleasant and knowledgeable to deal with.
Dustin diagnosed my problem with my furnace, finding a part that failed, and replaced it. He explained what he was doing as he did the repair keeping me informed. He was very knowledgeable and professional. I would recommend Dustin and Shafer's HVAC to anyone who needed their furnace serviced.
Thank you so much Chelsea for being so friendly and getting us set up with a tech right away. Josh Whitmire was amazing! He had our system up and running in no time. He was very knowledgeable and sweet. A true gentleman. I will tell everyone I know about the wonderful service we received.
Chris did a great job with my service work. He was extremely knowledgeable and went above and beyond the typical good service I get from your technicians. He took the time to do preventative maintenance work that other techs have not done. He kept his work area clean and orderly and treated me with respect. They do not come much better than Chris. He even showed up on time :) See you in the Fall.
From the initial call for service, the call from the tech with his ETA, the employees were very polite. The technician asked a couple questions and tested my AC system diagnosing the issue right away. He replaced the part and had the AC cooling down my house in 20 mins. Very nice, professional and knowledgeable. Would def recommend for all HVAC needs.

I highly recommend Shafer's! I have a geothermal furnace and it has not been easy to find a reputable company who can properly service. Pete from Shafer's HVAC is a pleasure to deal with. He's very knowledgeable, honest, and very responsive. I have a maintenance plan and am glad to have found a reputable and fair company to handle my heating and cooling needs.
The team of installers that put in a mini split for us were Profesional, clean, and quick. Austin and Tyler were in and out in no time at all with the unit blowing cold A/C. I highly recommend Shafers for any of my air conditioning needs!
