frequently asked questionsQ. Will I save energy if I turn my air conditioner off during the day when no one is home?

Your air conditioner was designed to maintain a temperature rather than attain it. On a 100° F day, the system is designed to maintain an indoor temperature of 75°, a 25° differential. If the house were allowed to reach 95° indoors, the unit would be unable to reduce the temperature to 75° because of the tremendous heat load the house and its furnishings would have stored. This means you should not turn off the system during high-heat conditions, unless you will be leaving your home for extended periods of time and are willing to wait a considerable time for the house to cool.

Q. My furnace is on, but there is no warm air.

Check your filter

Remember, you must regularly clean your filters. Allowing filters to become dirty or clogged can impair the equipment’s performance and may severely damage system components. This type of damage is not covered by warranty and can be very costly. It is important to make filter changing or cleaning a regular concern. Return air grills and registers should remain unobstructed at all times to assure proper airflow and prevent possible damage to the system. Filters should be cleaned or replaced every 30 to 60 days.

Check your thermostat

Your thermostat may use batteries to operate the control program, typically AA. Thermostat batteries should be replaced each year. The thermostat is designed to be set to 70° F in the winter. On a day to day basis, the system should be allowed to operate continually in the heat mode. To maintain the best comfort and performance from your system, do not turn off or substantially setback your thermostat. Attempting to save energy by turning off or substantially setting back the furnace will reduce comfort and save little energy when factoring in the extended period of the time required to recover.

Q. My furnace is on, but some rooms are still cool.

Check and adjust your room registers

The ductwork in your home is designed for “average exposure” situations. This means that you may wish to adjust some registers in your home to suit your needs and seasonal weather conditions. If one room is too cool during the heating season, partially close registers in other rooms to force more air to the desired room.

In two-story homes, seasonal adjustment of registers may be necessary to compensate for the heat’s natural tendency to rise. To offset this factor, adjust or close registers upstairs to force more heat to the first floor. You may also partially close registers in the rooms you don’t spend much time in, forcing more air to the rooms with more frequent use. Do not close a register just because it serves an upstairs area; instead, evaluate each room and only adjust the rooms that are the most important to you. To ensure adequate airflow and capacity of your equipment, we recommend that you close as few registers as possible.

Helpful tip: During peak winter conditions, the home will be more comfortable if you leave the thermostat set between 68° and 70° and set the “FAN” to “ON.” This will maximize the equipment’s performance and your comfort. With the fan on, warm air will circulate from upstairs to the downstairs; or in a single story, it will help to blend the air temperature and reduce the room to room temperature differences.

Q. What can I do to ensure that my furnace will work properly during the winter months?

Perform a pre-season furnace check

Each September, turn on your heating system to be sure everything is functioning as expected. To test your system, follow these seven simple steps each fall:

  1. Set your thermostat to the MANUAL position
  2. Set the fan switch to the AUTO position
  3. Switch the thermostat to HEAT
  4. Raise the temperature setting to a point that is at least 10° above the actual room temperature
  5. The furnace blower (fan) won’t start immediately and could be delayed by up to three minutes.
  6. Let the furnace run for ½ hour while checking for warm air coming from each register in the home
  7. After testing, reset your thermostat setting to your preference (typically 70° in winter and 78° in summer)

Q. There is smoke and a burning smell coming from my room registers.

Do not be alarmed by a little smoke and/or burning smell from your registers when using the furnace for the first time each heating season. These things are normal and will not last very long. However, should the condition continue, turn the unit off and contact Villara for a service appointment.

Q. There is no airflow to some/all rooms in my home.

Check and adjust your room registers

Check all room registers to ensure that they are open. The ductwork in your home is designed for “average exposure” situations. This means that you may wish to adjust some registers in your home to suit your needs and seasonal weather conditions. If one room is too hot or too cool, partially close the registers in other rooms to force more air to the desired room.

Check your filter

Remember, you must regularly clean your filters. Allowing filters to become dirty or clogged can impair the equipment’s performance and may severely damage system components. This type of damage is not covered by warranty and can be very costly. It is important to make filter changing or cleaning a regular concern. Return air grills and registers should remain unobstructed at all times to assure proper airflow and prevent possible damage to the system. Filters should be cleaned or replaced every 30 to 60 days.

Q. My furnace is off, but the fan is still running.

Your furnace blower (fan) will continue to run for three or four minutes after the thermostat has turned off the furnace.

Check your thermostat

Your thermostat may use batteries to operate the control program, typically AA. Thermostat batteries should be replaced each year.

Q. My system is on, but it is not cooling/warming my home fast enough

Your Villara heating and air conditioning system has been designed and sized to provide maximum comfort and energy efficiency, as outline by the State of California Title-24 Energy Requirements.

Below are the design assumptions used for calculating your home’s heating and cooling loads:

OUTDOOR DESIGN TEMPERATURE

Winter: 0.2% design temperature or 31° F for Sacramento. This temperature will be met or exceeded 99.8% of the time, all year. Approximately 22 hours per year will fall below this temperature. Summer: 1.0% design temperature, or 98° F for Sacramento is to be used for air conditioner sizing. This temperature will be exceeded about 78 hours per year.

INDOOR DESIGN TEMPERATURE

Winter: 70° F indoor, as dictated by the California Energy Commission (CEC). Summer: 75° F indoor, with a 4.5° swing factor, as directed by the CEC and Federal Housing Administration (FHA).

Q. My thermostat is set for 75°, but my house won’t get any cooler than 83°.

When outdoor temperatures rise above system design conditions, the indoor temperature rises accordingly. An indoor temperature of 83° with an outdoor temperature of 105° is possible.

Q. My air conditioning is on, but there is no cool air.

Check your filter

Remember, you must regularly clean your filters. Allowing filters to become dirty or clogged can impair the equipment’s performance and may severely damage system components. This type of damage is not covered by any warranty and can be very costly. So, it is important to make filter changing or cleaning a regular concern. Return air grills and registers should remain unobstructed at all times to assure proper airflow and prevent possible damage to the system. Filters should be cleaned or replaced every 30 to 60 days. Purchase replacement filters in the Villara Basket.

Check your thermostat

Your thermostat may use batteries to operate the control program, typically AA. Thermostat batteries should be replaced each year. The thermostat is designed to be set to 78° F in the summer. On a day to day basis, the system should be allowed to operate continually in the cool mode. To maintain the best comfort and performance from your system, do not turn off or substantially setback your thermostat. Attempting to save energy by turning off or substantially setting back the air conditioning will reduce comfort and save little energy when factoring in the extended period of the time required to recover.

Q. My system won’t turn on

Check your fuses and circuit breaker

A large percentage of service calls are attributed to fuse failure or tripped circuit breakers. This is mainly due to voltage interruptions or temporary low voltage in the area. Always check fuses and circuit breakers before calling for service on your equipment, as not doing so may result in you being charged for a non-warranty service.

If a fuse is blown, it should be replaced with the same size and type as specified on the air conditioner’s data plate. The fuse can be tested with an ohm meter to determine if it is good (some hardware stores provide this service). You cannot determine if the fuse is good by visual inspection. The fuses, if your system uses them, will be located in the electrical disconnect box next to your air conditioner. These fuses should be “time delay” fuses.

Circuit breakers are located and labeled in the home’s main electrical panel. To check or reset the air conditioning breaker make sure to turn the breaker all the way to the OFF position before resetting it back to the ON position.

Q. My air conditioning is on, but some rooms are still warm.

Check and adjust your room registers

The ductwork in your home is designed for “average exposure” situations. This means that you may wish to adjust some registers in your home to suit your needs and seasonal weather conditions. If one room is too hot during the cooling season, partially close registers in other rooms to force more air to the desired room.

In two-story homes, seasonal adjustment of registers may be necessary to compensate for the heat’s natural tendency to rise. To offset this factor, adjust or close the first-floor registers. You may also partially close registers in the rooms you do not spend much time in, forcing more air to the rooms with more frequent use. To ensure adequate airflow and capacity of your equipment, we recommend that you close as few registers as possible.

Q. What can I do to ensure that my air conditioner will work properly during the summer months?

Perform a pre-season A/C system check

Each April or May, turn on your cooling system to be sure everything is functioning as expected. To test your system, follow these seven simple steps each spring:

  1. Set your thermostat to the MANUAL position
  2. Set the fan switch to the AUTO position
  3. Switch the thermostat to COOL
  4. Lower the temperature setting to a point that is at least 10° below the actual room temperature
  5. This should turn on the outdoor condensing unit, check to be sure that it is running
  6. Let the air conditioner run for ½ hour while checking for cool air coming from each register in the home
  7. After testing, reset your thermostat setting to your preference (typically 70° in winter and 78° in summer)

Q. I have followed all of the trouble-shooting tips, but my system still is not working properly.
