When you schedule your yearly or bi-yearly maintenance session, our Apex Clean Air team may perform the following services: - Swap out or clean out your air filter - Check your pilot light and gas pressure - Clean out your condensate drain - Ensure your thermostat functions correctly and calibrate it if needed - Clear out any debris or dirt that might be blocking your heating system - Lubricate all your system’s mechanical parts and equipment Our crew will also inspect your system during this process, including checking every part. We can recommend replacements or repairs if we discover any issue beyond our regular maintenance. We’ll never perform an extra task without notifying you first and providing a free estimate.
