"Had 100 amp breaker replaced with 200 amp and multiple new lines run to the garage and added 100 amp in the garage. They were thorough and efficient and did the work as expected. Very professional and kept us updated if any potential delays and when new issues were found. I highly recommend and would hire again."

Heating Oil questions, answered by experts

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.

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.

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.

An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.

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.
