Summer and 73 degrees. Wonderful for your home, a sad day for those of us in the AC business. But we’re in Columbus,Ohio…so any day, it will be 90 degrees…or 25 degrees. And when that happens, you NEED your furnace and AC to work. Which is why we are recommending a furnace tune-up. Sort of like an oil change for your car. You do it so it WON’T break down. Need a few more good reasons: It will extend the life of your equipment It will get your furnace as close to factory specs as possible (which means it keeps it running like new) You will save energy and money on your energy bill. A well-tuned furnace runs more efficiently. Schedule your furnace tune-up before your schedule gets crazy and so does ours. Every tune-up comes with a free carbon monoxide check.
