"This guy is should be watched carefully. I had him replace a garbage disposal which he charged me way to much money for. He neglected to get the dishwasher drain pipe reconnected to the new disposal correctly, so it leaked. I had to call him back out to fix it. He tried to charge an additional 130 dollars. I told him he should reconsider charging me if he wanted to keep me as a customer. It was at that point he blew up. He started yelling and undid the work he had done. I had to kick him out of my house and off my property. I wasn't sure if he was going attack me physically or not. Beware, this guy should be avoided. I will be turning him in to the BBB as well."

Boiler Repair questions, answered by experts

At minimum, you should plan to have your HVAC system serviced once per year, usually leading into either the summer or winter before it sees heavy usage. If you live in a particularly cold, hot, or humid climate, consider servicing your HVAC system twice per year—once in the spring and once in the fall—to keep it running efficiently and prevent it from going down in the high-demand seasons. You can also schedule one-off services if you notice issues like uneven heating or cooling, poor performance, or strange noises from your equipment.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Most HVAC systems last between 10 and 20 years, with an average life span of 20 years. The individual components within an HVAC system have their own life expectancies as well. For instance, a furnace often lasts for 15 to 30 years, while a heat pump might need replacing after 10 to 15 years.

In general, it’s a good idea to bleed air from your heaters at the start of every cold season, before you move your boiler system back into active mode. Early fall is a common time for this task. However, some heating systems don’t need much manual bleeding because of automatic bleed vents and other components.

There are likely dozens of HVAC repair companies that service your area, and choosing the right one can be a tricky process. To hire the right HVAC technician, we recommend reaching out to local companies and ask the following questions:

  • Are you licensed and insured?

  • Do you have any third-party certifications?

  • Do you often work on my specific type of HVAC system?

  • Do you provide any warranty for your work?

  • Do you offer maintenance contracts for ongoing savings?

  • How many years of experience do you have?
