"I found Pol’s Heating and Cooling quite by accident. I was trying to contact my usual HVAC company, but they hadn’t returned my calls in several days. I eventually called the original salesman for my Trane units. Found out he had moved to a new company: Pol’s. We talked for a while. He suggested I try Pols for my problem. Nathan, one of Pol’s techs, arrived and did a great job for me. Knowledgeable. Courteous. Efficient. Thorough. Great communicator. I learned more about my HVAC system in the hour he was here than I had in years from my original supplier. Nathan even identified a roof leak I’d been trying to locate for months. The price for the work was reasonable and I felt sure it was done properly. I’m switching my future HVAC business to Pol’s Heating and Cooling."

FAQs for plumbing and heating service projects in Knoxville, TN

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
