Preventative Maintenance is so Important. Here's Why:


Air Conditioning

- Dirty condenser coils increase your electrical bill.
- Dirty evaporator coils can decrease efficiency, increase operating cost, and cause compression failure.
- A low or high refrigerant charge can cause compressor failure.
- Loose belts and worn pulleys decrease airflow.
- Improperly lubricated rotating equipment will eventually fail.
- Algae can plug a condensation drain which can cause expensive water damage.


Heating

- Heat exchangers can develop cracks, risking carbon monoxide poisoning.
- Dirty burners cause poor combustion resulting in heat going up the stack.
- A defective thermocouple will cause the furnace to shut down.
- Weak or dirty pilots can be extinguished causing the furnace to shut down.
- Safety controls left unchecked can cause dangerous problems.


Plumbing

- Help conserve energy and prevent scalding on your water heater.
- Hose bibs can get blocked and cause freezing.
