"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."

"Reportedly found a leak in my outside evaporator coil. Said that although my (1 year old) system had a 10 year parts warranty, that the manufacturer would only send a replacement coil so "someone" would have to dismantle the evaporator to replace the coil, and HE wasn't going to do it ! He then offered to "top-up" the Freon, for $900 ! When I said no, he then offered to do it for $500, "but that's today's price". Of course, I declined. I then had to pay his $65 "diagnostic fee" (for 20 minutes work). He asked me to make check out out to him personally, which I did. As is my practice, I endorsed the check "For Deposit Only", to which he objected, as he said he just wanted to go to my bank and cash it over the counter (not pay it into a bank account). I told him I wasn't changing it. I saw a copy of my cashed check today. He had scribbled his signature over my endorsement to obscure it. I wonder why he didn't want to pay it into a bank account ? Never again !"

FAQs for heating and air conditioning service projects in Knoxville, TN
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
