Aire Serv® has cold weather tips for HVAC systems
WACO, Texas (Oct. 10, 2014) – October is here and that means cold weather is not far off. Before the cold days come to stay, it’s important to make sure furnaces are up the task of working all fall and winter and air conditioners are properly maintained and stored so they are ready for spring and summer. These tips from Aire Serv will help ensure both the furnace and air conditioner will be ready for the colder days ahead.
The furnace
Make sure the pilot light is working properly. Older style units usually have a pilot light that remains on the entire time. Newer style units tend to have pilot lights that only turn on when the furnace is running. With either type unit, make sure the area is cleaned and there is no debris near the pilot light that can potentially be a fire hazard.
Heat pumps
Coils of heat pumps that are blocked by ice will not run efficiently. The ice build up will block proper heat transfer between refrigerant and the outside air causing the system to not run at peak performance. Make sure to keep the heat pump clear of snow and ice.
Air conditioning units
Remove snow and other debris such as leaves away from the unit. This includes keeping the underneath side of the unit free of leaves and snow as well as the back of the unit that faces the house. Never remove snow or debris using sharp objects. Objects with sharp edges can easily damage unit fins and refrigerant coils.
Check the guttering above the unit to ensure it drains properly and does not drip on the unit. Guttering that drops water on the unit needs to be replaced or repaired so that it drains properly.
Check the unit to make sure it is level. A unit that is not level will not run properly. A unit may settle over time. If the ground has caused the unit to sink contact a service professional so it can be properly leveled.
Window units
The best thing to do with window units is to remove them once the cooler weather starts. Once removed, properly store the window unit in a covered area like a garage. If it is not possible to remove the window unit, place a protective cover over the unit and make sure the area surrounding the window unit is properly sealed for the fall and winter months.
