This is a frequent problem here, often caused by a clogged condensate drain line. Humidity in our area leads to algae growth that blocks the drain, triggering a safety switch that shuts the system down. We perform a thorough drain line cleaning and treatment as part of our maintenance service to prevent this shutdown and protect your system from water damage.

Uneven cooling is common due to ductwork issues, insufficient insulation, or an improperly sized system. We conduct a detailed comfort analysis to diagnose the root cause. Our solutions often include sealing and insulating ducts, adjusting airflow with balancing dampers, or recommending system enhancements to ensure even temperatures in every room of your home.

We recommend professional maintenance twice a year—once in spring for your AC and once in fall for your furnace. This schedule is crucial for our climate to prevent the local issues of clogged drains from summer humidity and to ensure all components are ready for efficient heating and cooling, which helps maintain even temperatures and prevent unexpected breakdowns.
