General AC Service Items

  • Thermostat turned on?
  • Thermostat temperature setting low enough?
  • A/C circuit breakers turned on?
  • Outdoor unit safety switch turned on?

Indoor Blower Not On

  • Check “general items”
  • If your furnace is also part of your air conditioning, is there a switch on the basement stairway or next to the heater?
  • If your furnace is also part of your air conditioning, is the blower door on securely?

Outdoor Unit Not On

  • See “General AC Service Items”

Outdoor Unit Running – Pipes Are Frozen, No Cooling

  • Dirty indoor filters may have caused unit to freeze up. Change filters and run system in fan only mode for about 1 hour. Then switch back to cooling.
  • Blocked air return may have caused unit to freeze up. Remove obstruction and run system in fan only mode for about 1 hour. Then switch back to cooling.
  • Low refrigerant – If the above procedures do not solve the problem, the freeze-up may be caused by low refrigerant. Please call for service.

“It’s 100°F Outside – Why Can’t I Get My House Below 80°F?”

  • Most cooling systems are only designed to create a 20°F difference between indoor and outdoor temperatures. If you can get your house down to 75°F on a 95°F day, your system is working properly.

General Heating Service Items

  • Thermostat turned on?
  • Thermostat temperature setting high enough?
  • Furnace/heating circuit breakers turned on?
  • Heating emergency switches turned on?

Indoor Blower Not On

  • If your warm air furnace is in your basement or crawl space, is there a switch on the basement stairway?
  • If you have a furnace, is the blower door on securely?

Furnace Running – Not Enough Heat Coming From Furnace

  • Dirty indoor filters may have cause low airflow and low heat output. Change filters.
  • Blocked air return may cause low airflow and low heat output. Remove obstruction and run system.

“It’s 0°F Outside – Why Can’t I Get My House Above 70°F?”

  • Most heating systems are only designed to create a 70°F difference between indoor and outdoor temperatures. If you can get your house up to 70°F on a 0°F day, your system is working properly. High winter winds can affect the time it takes to reach your desired temperature.

Gas Smell – Call your utility company and/or Bovio Rubino Service immediately for service.

  • DO NOT light any open flames, DO NOT turn anything electrical either ON or OFF.
  • If smell is strong and present throughout house, vacate and wait for help.
  • When in doubt, play it safe.

Heat Pump Systems

  • Why do I occasionally see ice on the outdoor unit coils?
    • This is a normal function of a heat pump system.
  • Under certain conditions I see a plume of vapor rising from the outdoor unit, why is this so?
    • This is caused under certain conditions when the unit goes into a defrost cycle, and is completely normal.
