I have generally been happy with TN Bowes and for many years recommended them to my friends. Their customer service has always been solid but unfortunately technician quality has become very poor. I have had them install two separate systems now along with numerous maintenance and service calls. The first install over ten years ago has been running solid and the value was very good. Unfortunately, ever since then the quality has gone sharply down hill. I went back to them to update an aging heat pump and furnace. The furnace install in the attic was not properly leveled in the drip pan and leaked

Very pleased with T.N. Bowes’ on call serviceman Jimmy. He was prompt, courteous, neat, and thorough. His knowledge & critical thinking helped isolate & fix problem on my older system.

A two person crew arrived on time and were very personable. They took care of cleaning and replacing the filters and equipment and checking levels. I really appreciated that they spent time to let me know where the system stands and the current condition of the ducts and when I should be thinking about having the ductwork cleaned (not needed right now but probably in a few more years). Very professional.

We had two gentlemen to fix our vent for our dryer. They were considerate of our home, answered all my questions, showed us what was to be replaced and worked efficiently and steadily until finished. I was very pleased!!

Trent was fantastic in doing my seasonal AC tune up! I've used TN Bowes three times now and I've been happy with their service every time! Keep up the good work, I love an honest company with honest individuals.

When the heat pump in my house quit working, SMO Energy wanted to charge me $1,644 for a Carrier fan motor, and $377 for a controller board. After googling the part numbers, it became clear that they were trying to price gouge a senior citizen with a 140% markup! I called TN Bowes, and they quickly got out to the house and said I only needed the fan motor, and there was nothing wrong with the controller board. They charged me $764 for the brand new OEM part. I was with SMO for 20 years, but am now a TN Bowes customer!

Just completed installation of a new Carrier heat pump, furnace, thermostat, and hybrid electric water heater. Also TDE upgraded electrical service as sub to T N Bowes, to include a new hook-up for a generator that I asked for. Everything came off exactly as promised and was very expertly and professionally installed. Installers also left a clean worksite each day. Downtime was minimal. Couldn't have asked for a better experience! Enjoy!

Came home late from work tonight to find the upstairs unit was not working. Ran over to the neighbor who recommended TN Bowes as they have after hours service. Called, left a message on the emergency line and received a call right away. The tech (Keith) arrived in 45 minutes as promised. Within a moment he know what the issue was, fixed the problem and hung around for a few minutes to make sure everything was ok. Keith was kind , prompt,professional and honest.
