"My case was an urgent one, and the Improved Comfort Heating & Air Conditioning team resolved the issue promptly and effectively that same day. It happened to be Halloween, a day when HOA staff usually leave early, yet their responsiveness was exceptional. When I called Mahdi to inform him of the situation, he arrived as quickly as possible despite the heavy traffic and repaired the heating system efficiently. Their office staff also kept me well informed about his schedule and handled everything with great professionalism. I truly appreciate their outstanding service and have added the company to my trusted list."

Heating Oil questions, answered by experts

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.
