"Big thumbs up to Ryan and crew! Handled my new install with professionalism and great communication. I took advantage of CT Rebate and Fed Tax Credit and purchased an efficient, 1st model year, high tech system from Carrier. After install there were some minor issues with unit as first year products have. Ryan expedited service of unit and had it operational. And itâ s been running flawlessly ever since. I highly recommend using them and Iâ ve been in the service business for 30+ years and know both good and badâ ¦ they are good! *Side note: Ct rebate program not that good. From what I hear people are not getting appropriate amounts due back to them.. that includes me. You have to keep after them. This is in no way a reflection of Kellyâ s Heating and Cooling"

"Issue with Bell Mechanical This past August of 2024 we had a heat pump system installed in the house by Bell Mechanical. Unfortunately, we have had nothing but issues since with the biggest being no heat multiple times and now again today we are without heat in the majority of our house. It is freezing outside, we have a toddler and within the past week this is the 2nd time we have no heat (4th time since the system was put in). Not only is this a life safety issue, but it also is heart breaking to have your toddler tell you they are freezing. Looking for advice on next steps. We have never sued anyone or threatened to sue but this may be the time as we have had nothing but issues since the beginning. From the start we made it very clear that everything needed to be done to code and permitted. We were doing a lot of major renovations at our house and everything was being done to code and permitted. John (the salesman) at Bell said that was not a problem. John also told us that the only additional cost we could potentially incur outside of what he quoted us for the system and its installation would be a $500 fee for the installation of the heat strip. We accepted this and moved forward. After Bell removed our central air system and installed the new carrier system we got his with additional work needed at the tune of over 2k. Needless to say we were not happy. John told us the electrician they use and that if we used that electrician there would be no delay but if we used ours that it would cause a delay. So, we went with what John said as he was the expert. John got the electrician to come down a little in price which we were grateful for. Fast forward to when the building inspector came out to close out the permits for the work Bell did and other work being done at the house, the inspector told my contractor that the heat pump was not done to code. We were told that the electrical for it was not done to code and he could not close out the permit. My husband talked to the electrician Bell gave us who informed us that Bell told him to “cut corners” which was part of getting the cost down slightly. Reminder, we NEVER said to do this, we made it clear that everything needed to be permitted and even paid the permit fees to Bell. Back and forth with Bell and the electrician got the electrician to fix his work at no additional cost but Bell still needed to fix the outside plug which was not to code. Giovanni at Bell agreed that Bell would fix this issue at no additional cost. It has been 3 months now and Bell has still not rectified this issue and Giovanni and John are both nonresponsive to our follow-ups. Bell has also had to come out 4 additional times because our system was not working and again today, we have no heat. Today will be the 5th time they have to come out for issues on a system that is 4 months old. This is not OK. We have given Bell ample time to rectify the issues. Clearly they did not do the install properly and there is also the possibility we have a faulty system. We have never sued someone or went to court but then again, we have never had such large and costly issues."

Heating and air conditioning services FAQs

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified 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

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.

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.
