3 Tips to Get the Most Out of Your HVAC System

3 Tips to Get the Most Out of Your HVAC SystemWhile Portland might not have the most challenging climate, you can still run up high heating and cooling bills if you don’t plan ahead. With a few simple steps, though, you can help your HVAC system perform more effectively and efficiently.

Invest in an Energy Audit

Your furnace and air conditioner will have a hard time keeping you comfortable if all the warmth or cooling they provide is quickly lost through your walls and ceilings. Areas with insufficient insulation and air leaks around the windows, doors, utility line penetrations, and other areas waste energy, forcing your system to work harder and use more energy to maintain the temperatures you want.

During an energy audit, your technician will bring in equipment to zero in on points of energy loss so you’ll know where to invest in improvements. For example, using an infrared camera, your technician may discover you’re losing energy through the roof. You’ll then know to air seal the attic and add more insulation.

Keep up on Maintenance

During just one season, your furnace or air condition sustain minor wear and tear issues that have a major effect on their efficiency. Loose wires and corroded contacts increase electrical resistance, dust on the indoor evaporator coil makes it harder for the coil to cool passing air, and incorrect motor voltage and amp draw can cause excessive energy use.

As part of an annual maintenance inspection, your technician will find and correct problems like these to keep your HVAC system at maximum efficiency and prevent sudden breakdowns.

Upgrade Your System

If your furnace or air conditioner is more than 10 years old, it’s nearing the end of its life expectancy. With each passing year, HVAC equipment drops in efficiency and newly manufactured models are more efficient that older models were even when they were new. Upgrading to new, Energy Star-qualified models could cut your heating and cooling bills by up to 20 percent, assuming the system is correctly sized and installed.
