Change your air filters regularly.
Be sure to avoid blocking floor, wall or ceiling vents.
Make sure your outside condensing unit isn’t covered or clogged with leaves or debris.
Check to make sure the drainage system isn’t clogged.
Don’t run your system in cooling mode when outdoor temperatures are lower than 55° F or 13° C.
Have a Carrier^® expert clean your indoor coil regularly.
Check for water at the base of your outdoor unit. Water likely means the support base has shifted since installation and is no longer level.
Consider sealing or insulating your ducts.

Confirm that the furnace/boiler turns on and off via your thermostat by setting the temperature higher than the current indoor temperature and setting the system to heat mode.
Check the temperature of air supply grates or radiant system to ensure you’re able to feel warmth.
If you have an older thermostat that could have mercury switches, clean and level it to ensure it works properly.
Check all visible wiring and electrical connections for signs of damage like burns, unraveling wires and loose nuts.
Check vent connection pipe and chimney for rust or gaps. (Venting systems can deteriorate over time.)
If you have a gas or oil furnace, make sure you have a clean air filter in the proper size.
When you restart your system each fall, you might consider an inspection of the burners, combustion area, venting and even flame appearance

Wash once a year and handle with care. Soak the core in warm water and mild soap for three hours and then rinse under warm (not hot) water.
Filters in your ventilator are washable and should be cleaned every three months. Use a vacuum cleaner to remove accumulated dust and then hand-wash in warm water.
Regularly check the screen on the exterior intake hood and clean as necessary.

Changing the air filter is the only maintenance required. Filter life varies from home to home and is based on several factors, but most last from eight to 12 months.
