What is the average lifespan of an HVAC system?
The average lifespan is between 15 and 18 years.
How often should I change my air filter?
You should change the air filter every three to six months, depending on usage.
What size of unit do I need?
There are several factors that need to be determined. Our technicians will visit your home to conduct an assessment and determine the best unit for your space and your home's needs.
Should I cover my AC unit up in the fall and winter?
Keeping your outdoor HVAC unit covered during the off-season can be beneficial, as this helps keep debris out. It’s important to make sure that while the unit is covered, power is off at either the disconnect or the breaker to insure the unit doesn't turn on while the unit is covered. Be sure to uncover the unit before applying power back to your outdoor unit.
How can I increase the efficiency of my HVAC unit?
You can increase your HVAC unit's efficiency with regular tune-ups and filter replacements and by following a maintenance schedule. Decreasing usage whenever possible and turning the system thermostat to vacation mode if you are going out of town. If your thermostat doesn't have a vacation mode, turn your heating down to 55 and your cooling up to 80. Doing this can lower your energy consumption and also help with the unit's efficiency while away for long periods of time.
What temperature should I set my thermostat at?
Never set the thermostat below 65 degrees in cooling because the system may freeze, but overall, choose a temperature that is comfortable for you and your home.
How do I maintain more consistent room temperatures in my home?
Keep the furnace fan running. If you have a smart thermostat, you can often program it to periodically circulate the air by running the fan 15–45 minutes out of the hour to keep the air circulating in the home. This will help maintain consistent temperatures overall.
How often should I tune up my water heater?
Tankless systems should be tuned up, flushed, and descaled once a year, while tank water heaters need to be flushed and tuned up every two years.
How often should I replace the air filter in my HVAC system?
You should replace the air filter every three to six months, depending on usage.
What maintenance schedule do you recommend for high-efficiency HVAC units?

How long does an average HVAC system last?
The average lifespan is between 15 and 18 years.
Should I cover my AC unit during the fall and winter?
Yes, covering your outdoor HVAC unit during the off-season helps keep debris out. Ensure the power is off while covered and uncover before powering back on.
