Q&A

Why does my furnace in Marissa keep turning on and off (short cycling)?

Short cycling is a frequent issue here, often caused by a clogged air filter restricting airflow, an oversized furnace for your home, or a faulty flame sensor. It stresses the system and increases bills. Our technicians can diagnose the exact cause—whether it's a simple fix or a sizing issue—and provide a reliable repair to restore normal, efficient operation.

My thermostat in Marissa isn't keeping my home at the right temperature. What could be wrong?

Thermostat malfunctions are common and can stem from several issues: the unit may need recalibration, its location could be in a drafty spot or in direct sunlight, the wiring may be faulty, or it may simply be time for an upgrade to a modern programmable model. We'll check the placement and operation of your thermostat to ensure it's reading your home's temperature accurately and controlling your HVAC system properly.

What regular maintenance can prevent these common HVAC problems in our area?

Preventative maintenance is key. We recommend an annual professional tune-up for your furnace and AC. This includes cleaning critical components like the flame sensor and checking for proper airflow—which directly prevents short cycling—as well as testing and calibrating your thermostat. This proactive service helps catch small issues before they become major repairs, improves efficiency, and extends the life of your system.
