AC Freezing Up in Vallejo - FAQ

Why does my Vallejo home feel humid even with AC running?

What makes this service different in Vallejo?

Vallejo's delta location brings humidity challenges unique among Bay Area cities. Proper system sizing and dehumidification matter more here than in drier areas.

Do homes here really need air conditioning?

While summers here average 78°F - milder than inland areas - AC significantly improves comfort during warm periods. Many newer homes in the area include AC as standard.

What HVAC challenges do local victorian downtown face?

Homes built in the 1900s-2010s typically experience older systems throughout. We specialize in addressing these specific issues.

Why does my AC keep freezing up?

AC freeze-ups are usually caused by restricted airflow (dirty filter, blocked vents) or low refrigerant. Both prevent the coil from absorbing enough heat, causing moisture to freeze on the coils.

Can I just scrape the ice off my AC?

No, don't try to remove ice manually as you can damage the coils. Turn off the AC and let the ice melt naturally (run fan only mode to speed this up). Then address the underlying cause.
