Home/Services/Furnace Tune Up

Book it in
October.

Not December, when the first hard freeze has already found the fault for you and half the Lake is calling the same night.

A fall furnace tune up from 24 Hour Heating and Cooling is a full safety and performance inspection: burners, igniter, flame sensor, gas pressure, airflow, and a heat exchanger check for cracks.

Most of the no heat emergencies we run in December were already visible back in October.

The visit

Here's what your technician works through

Start to finish, in the order it happens. It's about an hour on a straightforward system, longer if we find something worth showing you.

1
Shut down and open up
System off, panels off, and a look at how it's been running. Soot, rust, scorching and water staining all tell a story before a single test happens.
2
Heat exchanger inspection
The safety critical one. We look for cracks and separation in the metal that keeps combustion gases out of the air you breathe. This is the check that finds a carbon monoxide problem before a detector does.
3
Burners and flame
Burners cleaned, then we watch the flame itself. Color, shape and steadiness tell you whether combustion is right long before anything fails outright.
4
Igniter and flame sensor
The two parts behind most no heat calls in this county. Both are cheap. Both are miserable to be replacing at midnight in January.
5
Gas pressure and connections
Pressure checked against spec, connections tested for leaks. Propane systems get particular attention here, and plenty of Lake properties run propane.
6
Blower, filter and airflow
Restricted airflow makes a furnace run hot and short cycle, which shortens its life. We measure it and change the filter while we're in there.
7
Safety controls and thermostat
Limit switches, pressure switches, thermostat calibration.
8
Run it and write it up
We watch a full heating cycle start to finish, then write up what we found and anything worth keeping an eye on. That record is also what keeps most manufacturer warranties valid.
About that heat exchanger check

As a furnace ages, the metal separating combustion gases from your indoor air develops stress cracks. When that happens, exhaust that should be going up the flue gets pushed into the house instead. Carbon monoxide is invisible and doesn't smell like anything, so a detector and an annual inspection are the only two things standing between a cracked exchanger and a serious problem.

Every furnace we service gets this check, on a tune up or a repair call, whether or not you asked for it.

Ready to get on the fall schedule?

September and October are the right window. By the first really cold night, everybody who put it off is calling at once. The appointment you wanted turns into an emergency call at an emergency rate.

Vacation and rental properties are worth doing early too. A house that's sat empty since October will tell you it has a problem at the exact moment you show up with family for the holidays. We can get in, check it and report back without you making the drive.

Amazing job by Brenton who went above and beyond to install a new furnace. His estimate was less than others for a high quality unit with ten year guarantee. Couldn’t ask for more.

Brenton answered the phone when I called and came and diagnosed the problem the same day. He was not the original installer but still worked with the supplier to get the part covered saving us over a thousand dollars. His communication and professionalism are outstanding.
