E S I Heating | Professional HVAC Services in Portland, MI

Short cycling is a common issue here, often due to a clogged air filter restricting airflow, a faulty flame sensor, or an oversized unit for your home. It's hard on your furnace and increases energy bills. We'll diagnose the specific cause—whether it's a simple cleaning or a more complex thermostat or sizing issue—and get your system running smoothly again.

Yes, that's a frequent problem in Portland, often from our hard water causing mineral buildup in the drain line. We'll clear the blockage using specialized tools, flush the line to prevent immediate re-clogging, and can install a safety switch to alert you to future issues. Regular maintenance can help prevent this messy and potentially damaging problem.

We recommend bi-annual tune-ups: one in spring for your AC (focusing on clearing the condensate drain and checking refrigerant) and one in fall for your furnace (checking the heat exchanger, cleaning the flame sensor, and replacing the air filter). This proactive care helps prevent short cycling, improves efficiency, and extends the life of your system, saving you money on repairs.
