Frequently Asked Questions :
Question: Is it OK to run my furnace fan in the “ON” position instead of “AUTO”?
Answer: Not only is it OK, we recommend it. Running your furnace with the fan set to on keeps the air constantly circulating to make you more comfortable and filter the air. Running your furnace fan this way uses very little electricity.
Question: Why can’t you give me a “ballpark” figure on the phone for a new air-conditioning and furnace system?
Answer: It is very difficult because there are so many variables involved. It would not be fair to you or us to try and “guesstimate”.
Question: At what temperature should I set my thermostat if I go away for a few days or even longer during the winter?
Answer: For a gas furnace we recommend about 55 degrees. It is low enough to save you energy and money but warm enough to protect your pipes and other vital parts of your structure. Also, it is a good idea to turn off your main water supply, even if you are only going to be gone for a day. A water leak could cause very costly damage to your home.
For a Heat Pump, we recommend about 65 degrees if running in normal Heat Pump mode. Heat Pumps need a higher indoor temperature to work properly. You can also turn the Heat Pump over to Emergency Heat Mode and then you could set the thermostat down to about 55degrees.
Question: I have an arrow on my furnace filter but I do not know which way it should point?
Answer:The arrow should point in the same direction as the air flow. In most cases, it will point towards the Furnace or Air handler and should fit between the return air part of the system and the furnace.
Question: How often should I change the standard throw-away filter on my furnace?
Answer: You should change your standard furnace filter every 4 to 12 weeks. Believe it or not, a filter actually becomes more efficient as it gets dirtier, up to a point. After peak efficiency is reached, the efficiency drops again. Inspect the filter every 4 to 12 weeks and use your own judgment. Do not let the filter get “clogged” as this can cut down on the efficiency and/or cause damage to the unit.
Question: Can I troubleshoot before calling for service?
Answer:The answer is “Yes.” Here are some simple procedures you can perform before going to the expense of a service call:
- Check disconnect switches. (indoor and outdoor if you have a split system)
- Make sure that circuit breakers are ON and that fuses have not blown.
- Check for sufficient airflow.
- Make sure air filters are clean.
- Make sure that supply-air and return-air grilles are open and unobstructed.
- Check the settings on your thermostat. If you want heat, make sure the temperature control selector is set above room temperature and the SYSTEM switch is at HEAT.
- The FAN switch should be set at ON for continuous blower operation or AUTO if you want the blower to function only while the unit is operating.
