Home Improvement Guide: Tips from an HVAC expert
1. Get a tune-up twice a year
“There are a lot of moving parts on these units. For the summer we do a cooling adjustment, but also in the fall we do a heating adjustment, and that heating adjustment is not just for efficiency,” Koehner said. checked to make sure they are clean, to make sure they work properly and to make sure everything is safe too.So the cooling adjustment is primarily for efficiency, but the heating is for efficiency and safety.”
2. Find a comfort number
To keep HVAC units running efficiently, especially in winter and summer, while avoiding wasting energy, Koehner recommends choosing a “comfort number” and staying as close to that temperature as possible, rather than drastically different level to change the temperature more quickly.
“In general, find your comfort number and stay within two degrees, one way or another,” he said. “You don’t want to put stress on the device during these super hot days because it’s designed to be serviceable.”
3. Change filters
Homeowners should replace air filters regularly to keep dust and other debris out of HVAC units or ducts.
“A filter replacement is one of the easiest things homeowners can do to ensure the unit is operating at 100% capacity and efficiency,” said Koehner.
4. Check Carbon Monoxide Alarms
Koehner said that while many homeowners probably already have a carbon monoxide detector, they may not know where to place it or when to check.
Detectors, which measure levels of harmful carbon monoxide that can be fatal, should be placed near a vent if possible. Homeowners should also check the expiration dates of their units.
“One thing people don’t realize is that carbon monoxide detectors have a small sensor, and after a while it goes bad,” he said. “For the sensors in these carbon monoxide detectors, you look on the back of a carbon monoxide detector and there you see an expiration date. Most people don’t know that; they’ll think it’s only a few years old and they’ll find out it’s about eight years old.”
5. Keep the air conditioning on when you’re out of town
•Koehner said that because air conditioning units also control the amount of humidity in a home, homeowners should leave the air conditioning on when they go on vacation to prevent excessive moisture from entering the home. Units can be set a few degrees above normal to keep costs down.
