Keeping your HVAC system in working order is one of the responsibilities of owning a home in Cary, NC. Some problems may not be the mechanical system but simply indicate a bad thermostat. Here are some key indicators that your thermostat may be malfunctioning and needs a replacement:
Old or Outdated Thermostat
Just like your HVAC system, your thermostat has a finite service life. In most cases, this is about 10 years. You should plan to replace your thermostat when replacing your air conditioner, which lasts on average 10 to 15 years.
Your thermostat’s display may give several indications that there’s a problem. This may be a blank screen, inaccurate temperature reading or other display issue. If your thermostat is battery operated, replace the batteries to see if that solves this issue.
Irregular Cycle Length
You may notice your system running longer or shorter than usual, indicating that it needs some attention. A thermostat malfunction could be the cause, but it may also indicate significant AC repairs on the horizon.
Your Home Feels Uncomfortable
As your system runs, it should make your home more comfortable. Part of the comfort over the summer is removing humidity from the air. If your home is muggier than usual or not achieving your desired temperature, a malfunctioning thermostat may be the culprit.
Large Temperature Shifts
A thermostat senses changes in temperature, triggering the system to turn on and off. If it’s not sensing the right temperature, you may notice larger temperature swings before cycling on.
Many thermostat malfunctions are difficult to differentiate from other HVAC system problems. Start by checking the batteries in your unit to ensure that it has the right amount of power. If that doesn’t work, call a professional to troubleshoot your problem.
If your thermostat is old and needs replacing, it might be time to upgrade your entire AC system. Call today to schedule a new air conditioner consultation with one of the expert service technicians at Quality Comfort Services, Inc.
