We have all been there, early one winter morning you get out of bed and realize the house is much too chilly. Or perhaps one summer afternoon you notice the house is much warmer than it should be. Don’t panic, here are a few things to check before you call your favorite service company:
Filter: This is an often forgotten item that can make any heating and cooling system grind to a halt. Your system needs good airflow to work properly, and a dirty filter will keep that from happening. If you use disposable or washable filters, replace or clean them once a month. If you use longer time frame filters, replace or clean them as recommended by the manufacturer. Realize too, that in dusty locations or with other conditions like excessive pet hair your filter maintenance intervals may be shortened.
Circuit Breakers: It’s a good idea to be familiar with the location of your Circuit Breaker panel anyway. Your heating and cooling system ties in to this panel with dedicated feeds to the individual appliances. A Circuit Breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
Occasionally, the circuit breaker may trip during the normal operation of a system. If this happens try resetting it by turning it completely off then back to the on position. If it continues to trip, there may be a more serious problem, and you should have the system serviced.
Thermostat: Don’t overlook the obvious. The thermostat may have been accidentally changed to an unexpected setting. If your thermostat uses batteries, as they near the end of their service life they can cause intermittent failures. Keep some extras handy just in case.
