Under normal conditions, the thermostat activates the HVAC unit when the indoor temperature rises or falls below a preset threshold. If the unit fails, it won’t activate the system according to the chosen settings. Click Here for some ways to determine whether the home’s thermostat has failed and to determine the nature of the cooling or heating issue.
Have it Tested for Correct Function
When the thermostat senses a temperature change within the home, it compares the change to the preset level to determine whether to turn on the HVAC system. A discrepancy may exist between the indoor temperature and that sensed by the thermostat, and the system may not activate. Testing can be done by setting the thermostat at least five degrees colder or warmer than would be expected. This can overcome the thermostat’s intolerances and trigger a response if the unit is still functional. However, if it doesn’t work, it’s time to call a company like J & S AIR INC in Lakeway TX.
Check for Other Failure Causes
Although the home’s cooling and heating system may seem simple, multiple problems can cause a failure. For instance, a temporary electrical condition can trip a circuit breaker, causing the system to fail. Inspect the breakers to ensure the ones for the HVAC system are turned on, and check the thermostat’s other settings to determine if they are correct. If this inspection indicates proper function but improper settings, consider getting a programmable unit that allows precision settings.
Inspection and Manual Bypass
Homeowners should have this check done by a professional in most cases. The test starts by turning the circuit breakers for the HVAC system off. Next, the wires for the thermostat are inspected for proper connection and tightened if necessary. If the wires are connected properly, the technician will short them and turn the breaker on. If the system turns on, the thermostat may be in need of repair or replacement.
Most people take the home’s HVAC system for granted and don’t think much about it until it fails. However, not all failures require a complex fix, and in some instances, a malfunctioning thermostat is the only issue. By hiring an HVAC professional such as J & S AIR INC in Lakeway TX to perform the tests and fixes listed here, a local homeowner can determine the nature of the problem and restore comfort to the home.
