Heating Oil questions, answered by experts

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives).

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

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.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

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.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.
