Frequently Asked Questions

1. Where should I keep my thermostat in the summertime?

We advice you to keep the thermostat set where you are comfortable. However, Setting the thermostat below 72 can sometimes cause you’re A/C to freeze up.

2. What causes my A/C to freeze up?

• Setting the thermostat too low
• Ductwork problems
• A dirty furnace filter, a dirty furnace blower, a dirty Evaporator, low on refrigerant, too much refrigerant
• If you are having this problem, call us so we can diagnose it and repair it

3. How can I get better performance out of my A/C?

• Keep you thermostat set at one temperature all the time
• Close blinds and drapes to keep the sun out
• Don’t turn the A/C on when you get home from work and expect it to cool your home properly. When a home is hot the A/C will usually lower the temperature 1-2 degrees per hour
• Make sure your filter, evaporator and condenser are clean and free of debris
• Have Rock Heating perform annual maintenance on your Air Conditioning system
