Tetteris Heating & Air

Tetteris Doesn’t Stand by Their Work We hired Tetteris to install a boiler furnace in November 2022, and now the pressure relief valve is leaking. Despite the furnace being under warranty, Tetteris has completely failed to address the issue. After a month of trying to get in touch, their team finally showed up on November 15, 2024, only to admit the leak was caused by their poor installation. They promised to schedule a fix, but since then, we’ve been completely ignored. Tetteris is unprofessional, unresponsive, and unwilling to stand by their work. Do yourself a favor and avoid this nightmare of a company at all costs.

The most horrific experience I've had working with a contractor. I was assured that the work would be complete in 5-7 business days. The owner reached out to me constantly to get me to sign the proposal and answer my questions, but as soon as I signed and put down the deposit, he disappeared. MONTHS later, after many unanswered phone calls, his team finally "completed" the job. His team didn't do many of the items we discussed (even though I was willing to pay more for them). The communication was awful- it was impossible to get someone on the phone or get a clear timeline. It's so sad to spend so much money with someone and get treated like complete garbage. I later found out that the "total replacement" didn't include a basic backup heating element that any reputable vendor would have provide., or at least included in the proposal. They disconnected the 20 year old heating element and didn't hook it up to the new system. It took another month after they did the install to get any warranty paperwork. Honestly, this is just the tip of the iceberg- this company is bad news. I would avoid at all costs.

Tetteris installed a heat pump unit in my attic little over a year ago. Started leaking month ago from a hole in tape on end unit into my attic space instead of leak pan and I have water damage now on second floor. They came out retaped the end unit and lifted it up, put in another drain pipe and moved the pan underneath leak and charged me $125. I have no confidence it won't leak again. They said leak into living space was my entirely fault cause I didn't replace filters enough and melting ice block overwhelmed a one inch drain pipe. Hard to believe as Ice doesn't melt that fast and it should have leaked into pan I think at the very least and not into attic drywall. What's the point of a backup system if it doesn't work. Had unit before this for 20 years and never had this problem. My view point is it was some kind of faulty installation. If they had taken some responsibility of the non working backup I would not have written this review but they were happy to put entire blame for unit leaking into attic on me. Quality and Professionalism rated low on second call due to not taking any responsibility of non working backup system and hole in tape contributing to leak in attic.

After several years of shoddy furnace repairs, replacements and guesswork from our propane provider, I decided to find another service. I quickly got a call back and appointment from Tetteris Heating and Air. After a brief diagnostic, Greg Shaeffer almost immediately assessed the problem was a malfunctioning gas valve. After replacing and converting the valve, he discovered that the old valve had not been installed or converted properly by the previous company. Greg was very professional, helpful, friendly and didn't mind answering any questions I had. I couldn't be more satisfied with the work and service that Tetteris provided. Highly recommended!

All went very well! They were very responsive to my inquiry. I had anticipated a few days before anyone would come out due to the heatwave we were experiencing, however, to my surprise they came out the very next day as promised. I even had asked for them to install a replacement thermostat which they did as well.

These guys were great. Fast, courteous, clean, and a fair price. I’m glad I took the time to find them on Angies list.

Great, fair pricing

My experience with him was top notch. He was accommodating to my schedule. I work nights and he was willing to come to my home in the early evening instead of normal business hours. He assured me the fix of the leak would hold until the end of summer but there was a chance that I may need a new unit next summer since the unit is over 10 years old and the leak was pretty severe. I had no other trouble with the unit the rest of the summer. His price was reasonable and he was friendly and efficienct. If I need a new unit next summer I will definitely use Tetteris Heating and Air for the replacement.

It went greatl, the price was very affordable and they were very professional

Excellent
