Hamilton Heating and Air: Qualified HVAC Repair Serving Greenfield 46140

Common signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your cooling bills. If you notice any of these, it's important to call us promptly. Refrigerant leaks reduce efficiency, strain the compressor, and can lead to costly repairs if left unaddressed.

We generally recommend changing standard 1-inch air filters every 1-3 months for most Greenfield homes. Homes with pets, allergies, or higher dust levels may need monthly changes. A clean filter is crucial—it protects your system from dust and debris, maintains good indoor air quality, and prevents the reduced airflow that makes your system work harder and less efficiently.

First, check your thermostat settings to ensure it's set to 'cool' or 'heat' and the temperature is correct. Next, verify the circuit breaker for the indoor and outdoor units hasn't tripped. Finally, inspect and replace your air filter if it's dirty, as this is a very common cause of poor performance. If these simple steps don't resolve the issue, give us a call for a professional diagnosis.
