Understand your system before you make a decision.

Plain-language answers to the symptoms homeowners call us about most — cooling problems, water where it shouldn't be, energy use, routine maintenance, and how to weigh a repair against a replacement.

Common questions

Know what your system is telling you.

Six things homeowners ask us most, answered without the sales pitch.

Evaporator coil iced over inside an air handler cabinet
Cooling

Why is my AC freezing up?

Ice on a coil or line usually points to restricted airflow or a refrigerant issue. Turn the system to fan-only to thaw it, check the filter, and have the cause diagnosed before running it again.

Water & Drainage

Where is this water coming from?

Most indoor leaks trace back to a blocked condensate drain, a full drain pan, or a frozen coil melting. Shut the system down to limit water damage and get the drain path inspected.

Efficiency

Why did my energy bill jump?

A sudden increase often reflects reduced efficiency: a dirty coil, duct leakage, a failing capacitor, or a system running longer to hit the same setpoint. Measurements identify which.

Decision Guide

Repair or replace?

Age, repair cost relative to replacement, refrigerant type, and how the system has been performing overall all factor in. There is no single rule — the numbers should be shown to you.

Maintenance

How often should filters change?

It depends on filter type, occupancy, and pets. Check monthly and replace when the media is visibly loaded rather than following a fixed calendar date.

System Care

What does a maintenance visit actually cover?

A precision tune-up is measurement work: electrical values, airflow, temperatures, drain condition, and safety checks — recorded so this season can be compared to the last one.
