"Their tech came to our townhome for the HVAC heat pump issue, spent more than 3 hours diagnosing the issue and then told us that we had to replace the zoning control board and the thermostat at $1400 in total. We were charged $390.00 for the diagnosis. We were not convinced by what he told us. Then, we called another HVAC contractor from different company to look at the issue. He was able to pin point the issue with the unit in 15 minutes and fixed it by refilling refrigerant at around $300! What a difference! I will never trust and use Premier HVAC Mechanical Corporation again!"

Boiler Repair questions, answered by experts

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

A poorly maintained boiler can lead to serious issues like deadly carbon monoxide poisoning, so schedule regular maintenance services. Of course, it’s also a good idea to check your carbon monoxide detectors in your home to make sure they’re working properly. Moreover, when you forget to maintain your boiler, small problems can lead to something much more serious, which will cost you more money in the long run. Repairs average around $400, while a full replacement can total over $6,000.

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.

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.

There are a couple of signs that will tell you it’s time to bleed the radiator. If the radiator is making noises, it’s typically because of trapped air, which you can release by bleeding the radiator. You can also test the radiator by turning on your heat and then placing your hand near the top and bottom of the radiator. If you feel cold spots, particularly at the top of the radiator, it’s time to bleed it.
