Common signs include the outdoor unit not turning on, a humming sound without the fan spinning, or the fan running slowly or intermittently. This often leads to warm air from your vents and can cause the compressor to overheat. If you notice these issues, it's best to call for service promptly to prevent further damage to your system.

We recommend checking your air filter monthly and replacing standard 1-inch filters every 1-3 months. In Milford, factors like higher pollen counts in spring or increased system use during summer and winter can lead to faster clogging. A clean filter is crucial for maintaining good airflow, improving indoor air quality, and preventing strain on your HVAC system.

Absolutely. A severely clogged filter restricts airflow, forcing your furnace or AC to work harder. This can lead to frozen evaporator coils in summer, overheating in winter, higher energy bills, and premature wear on critical components like the blower motor or heat exchanger. Regular filter changes are a simple, cost-effective way to protect your entire system.
