Importance Of Servicing Your Heater Breakdowns Don'T Have To Happen
The importance of having your heater serviced.
It is getting cold out there so it is time to start using those heaters.
Your heating and cooling system is probably the most expensive piece of equipment in your home. Similar to your car you should do tune ups to prevent a break down and protect your investment.
Regular tune ups help prevent breakdowns, which in turn means fewer repairs, lengthens the life of your equipment and helps keep your family safe.
Are you not sure you need a tune up? Well studies show that most heating and cooling systems don’t perform to manufactures specifications. Of the systems checked 90% were said to have efficiency problems resulting in higher energy bills and 60% had poor airflow and more than 80% were operating in not so great (dirty) conditions resulting in early mechanical failures.
By taking care of your heating and cooling system you can make sure you prevent emergencies down the road.
What does a tune up cover?
19 point tune up
- Check Thermostat Operation
- Calculate Operating Efficiency
- Check or Measure Airflow
- Inspect the Ducts
- Check System Disconnect Box
- Check / Test Safety Fuses
- Inspect Main Contactor Switch
- Check Start Kit, Relays, & Transformer
- Test Run Capacitors
- Check Compressor Operations
- Check Refrigerant Levels / Pressures
- Oil & Test Condenser Motor
- Inspect the Condenser Coils
- Oil & Test the Indoor Blower Motor
- Inspect the Evaporator Coils
- Check Condensation Drain / And Pan
- Inspect the Plenum
- Check Insulation Tubes / Panels
- Test Safety Controls
If you have a gas furnace and have not turned it on yet you will make sure the pilot light comes on and make sure the system is venting properly with a carbon dioxide meter.

how do i check the contactor and relay coils?
For my A/C unit, I opened the pump relay today, set my multimeter to ohms and rx1, and placed both prongs on the coil. The multimeter did not budge from infinity.
Also, how do I check the contactor coil?
Here's my system:
I'd like to test it because:
1) No conductivity in
a) thermostat
b) secondary on transformer -installed a new one, smoked.
2) Condenser - fan spins when I press in the contactor.
3) Tested all wiring from transformer / relay / stat / board. All show near 0 resistance.
cap not leaking oil or bulging
Check the contactor coil for voltage.If it has voltage and is not pulling in ,the coil is bad.Replace the contactor.
If the transformer keeps smoking,there is a short somewhere.
You really should buy a transformer with a small 3 amp circuit breaker on it so you won't fry another one.
ALL of the components in your a/c have a coil ohm reading.
The way to tell what the reading should be,is to get a good one and check the ohms on it.Then check the one in question and compare it with a known good one.If the ohms are way off,that is your problem.
Disconnect the coil wires from the contactor,reversing valve,blower relay,etc ,set your meter to R+1 ,and ohm the coils out.
Again every coil should have an ohm reading usually around 18,25,or 35.Somewhere in that area.
Most often,the majority of the time ,I'LL SAY IT AGAIN,the short is usually due to a 24 volt wire touching the cabinet or copper in the outdoor unit.You have to look REAL CLOSE to find it.All it takes is a TINY knick to short agaist the ground,overamp and smoke the transformer.
Good luck
