Our Customers Love Us!

My heat pump had to be replaced and I have been a customer of Tim Off’s for years so that is who would replace it. The sales rep, the installers, and the technician were very professional. I was very happy the way everyone worked together. Tim Off Co. should be very proud of this team and proud to send them to any job. I was very satisfied.

We have used the services of Timothy Off and staff since moving into the community over 10 years ago. The staff and service techs have always be friendly, knowledgeable, efficient and hard working. We have seen the same “techs” at our home a number of times (always thought it was a good sign that employees enjoy working at their company). Pricing has always been fair and reasonable. I strongly recommend you consider their Annual service contract. Maintaining the equipment is critical. Give them a call, you will not be disappointed.

This is a company with high standards, fair prices and excellent technicians. I have a contract with Timothy Off Heating and Plumbing and each time the technician arrives to service the unit, he is prompt, thorough, friendly, and knowledgeable. Several years ago, Tim put in a UV lamp for mold prevention and also built a space for a larger air filter for better air quality. Both of these have made such a positive difference in the air quality in my home. I believe that the pricing was fair and the work was completed on time with no mess. I have recommended Timothy Off to several of my neighbors and they have been pleased with the quality and pricing of the work. This is a company that does things right the first time. I highly recommend Timothy Off Heating and Air Conditioning.

I just wanted to take a moment to say it was nice to see you again and to thank you and your crew for the outstanding job everyone did in installing my new HVAC system, water heater and sump pump. From the beginning of the project Bruce Berry was simply excellent. He did a home inspection, sized my system and offered several options to meet my needs. He was also quick to respond to my questions and did so in a thorough, friendly and professional manner.

Chandler and Dan did a fantastic job of installing the new system despite some challenges beyond their control. The weather was awful that morning and we even lost power briefly but Chan and Dan never missed a beat. The simply donned miners hats and kept working. They were great! Ken did a great job of testing the system and explaining the new thermostat to me.

Mike installed the water heater and sump pump and was also excellent. He answered my questions and worked quickly and efficiently to get the old water heater drained and removed and the new one installed along with the sump pump. When I noticed that the new water heater had some dents and scratches he was quick to agree that I should have a new one and called in the issue to you right away.

Thanks to you as well, Tim, for bringing out that new water heater on a moments notice. It was just one more example of great customer service! That about sums up my experiences with your fine organization – Great Customer Service!

Please pass along my sincere thanks to the whole crew! You should be very proud of them. They are a great team!

Wishing you all my best for your continued success!


“We just wanted to thank you for the lovely delivery. The basket of cookies were such a nice surprise and absolutely delicious. Our younger son was the first to try them as he carried them from the door. We appreciate the thoughtfulness and your service as a new customer”

Sharon & Bob

“Thank you all for the wonderful service you provided us! From start to finish, the job could not have been done better. Bruce came out to give us an estimate on a whole new system the same day I called and then had a copy in my hand the next day. We were scheduled for install within a very reasonable amount of time, and your install guys (Chandler & Dan) were wonderful, friendly & courteous. They even made sure the workspace around the unit was completely cleaned up before they left. The “Thank You” basket you sent was also such a nice touch. The referral to you came from John & Karen, just so you know, and now we will be spreading the good word too!”
