You might be someone who loves warmer weather and who has been looking forward to the end of heating season, but that doesn't mean you can simply turn off your heater and let it sit for the next few months. Give it some quick care before shutting it down and switching to the cooling system in your home so that next fall, the heater will be almost ready to start up again.
DIY Physical Maintenance
There's some fast physical heating system maintenance that you can do first. Change the furnace filter and any return vents in the home. There's no sense in leaving dusty filters sitting in those for the summer (and if your heating and cooling systems use the same ductwork, you need the return vent filters to be clean anyway). Changing filters takes just a few minutes, even when you have several of them in a big home.
Next, look over the parts of the system you can see for leaks (in oil- and water-based systems) and signs of corrosion or damage. A heater repair company will have to fix that damage; don't attempt to do it yourself.
Turn It on One Last Time
Start the heater one last time and actually time, with a watch (or a stopwatch app on your smartphone) how long it takes for the heater to cycle off. If it takes only a couple of minutes from start to finish, have the heater and thermostat inspected for short-cycling. Get that fixed now before the rush in fall to get heaters ready for cold weather. Also listen for extra noises, rattles, and other odd things that you don't think should be present.
Don't Forget Portable Heaters
If you have space heaters, remember to prepare them, too. Dust them off, including the cord, and wrap them securely in plastic when the heaters are cool. If they have brand-specific covers, use those, but you may still want to encase them in sealed plastic to keep bugs out while the things sit in storage.
Have a Combination Heater/AC Seasonal Checkup
Finally, even if all seems well with your heating system, have a heater repair company give the system a once-over along while checking out the cooling system in your home. That way, you can take care of any lingering heater problems while getting the rest of the HVAC system into shape for warmer weather. If the heater company you want to use does not work on cooling systems, too, then you will have to make separate appointments with different companies. But if you can get a combination service appointment, that will make things a lot easier for you.
