SelmerAir - Peoria's Professional HVAC Repair

An improperly sized system is a common issue here. An oversized AC will short-cycle, cooling your home too quickly without removing enough humidity, leaving it clammy. An undersized unit will run constantly, driving up energy bills and failing to keep up on our hottest days. At SelmerAir, we perform a detailed Manual J load calculation to determine the exact capacity your Peoria home needs for maximum efficiency, comfort, and longevity.

If you notice your Peoria home isn't reaching the set temperature, rooms feel uneven, or your system cycles on and off erratically, it could be a calibration issue. Dust, age, or location (like in direct sunlight) can cause thermostats to read inaccurately. Yes, our HVAC repair experts can diagnose and precisely recalibrate your thermostat or recommend a modern, programmable model for better control and energy savings throughout the year.

Our Peoria-focused maintenance service is designed to catch small issues before they become big problems. We thoroughly clean components, check refrigerant levels, inspect electrical connections, and—critically—test and calibrate your thermostat for accuracy. We also assess system performance to ensure it's operating at its designed capacity, helping to prevent the inefficiencies of improper sizing from worsening over time. Regular maintenance is your best defense against breakdowns and high bills.
