We can't praise Ryan, Mark, and Troy enough. Numerous jobs were completed for us over the last few years (plumbing,... electrical, HVAC), all jobs were completed at a high level, no complaints. It's a refreshing change of pace doing business with people that are so professional. I wish them the best, and will be asking for their help in the future!read more

Very pleased with Ryan's work. Very professional, quick and trustworthy. He repaired very quick our furnace. It was... initially diagnosed dead by the competition that had left us without heat and a very high replacement quote. He has proven that he will not charge you for unnecessary more

Ryan, Troy and Mark are an AMAZING CREW! They are very personable, they are experts of their respective trades, and... they are diligent workers. We recommend their services to anyone who desires quality HVAC/Plumbing/Electrical work at a reasonable price. They will be returning in the near future to install a water softener and to perform outdoor electrical more

Sheaffer Mechanical is the only company I call for my heating and AC issues. They are super honest, very fast, and... don't overcharge like many of the other companies out there. I just wish all contractors were as easy to work with as these guys!read more

“They are always helpful no matter the day or time. Ryan just came through for me again when my furnace stopped working.
Thank you so much!!!”

James Stambaugh

“Sheaffer Mechanical is my choice of home utility work until I move. Mark has been great and so has the Owner. They have awesome service and great customer interactions. It’s very hard to find great people because all they want is money and go. Ryan has given some great advice which I’m putting into place. Once again thanks so much.”

Brittany Hoeschele

“Sheaffer electric went above and beyond to ensure our electric panel is safe and up to code. Appreciate the timely and quality work!”

Scott came out at his scheduled time on a SATURDAY when my air conditioning went out. He had to search for a part that day. He fixed my air after running to a few places and was very reasonable in his price. I will only be calling this company and requesting Scott Schaefer every time! Wish I knew about him years ago! Thanks Scott!

Jim Teats

“Ryan went to great lengths every time he was needed. The last was to install a new AC unit. He had it installed and running in 1 day with a brief visit to check everything the following day.”

“We just bought a 135-year-old house that needs a lot of work. My first, major concern was the boiler. After searching for HVAC technicians online, I found Sheaffer Electric and read all the glowing reviews. I called and set up a time for Ryan to come out. He arrived…read the entire review here.
