About Allseason Mechanical

Founded in 1989, Allseason Mechanical has built a reputation in San Diego, CA as a straight-shooting locally-owned hvac contractor that doesn't push system replacements when a repair will do. The team is unusually rigorous about indoor air quality and ventilation work in addition to core heating and cooling, and is one of the few local shops that will quote both a repair and a replacement option on the same visit so homeowners can make an informed call. NATE-certified, state-licensed, EPA refrigerant-handling certified, and proudly insured.

Allseason Mechanical serves homeowners across San Diego, CA and surrounding ZIP codes including 92101, 92103, 92109, 92115, 92122. Pricing is up-front and quoted in writing before any work begins, with no obligation if the estimate isn't right for your project.

★★★★★
They diagnosed an issue three other contractors had missed. Fixed it in two hours and didn't charge for the diagnostic visit. Easy 5 stars.

★★★★★
Came out for a second opinion after another company tried to upsell us into a $9,000 job. Turned out to be a $400 fix. Fair, knowledgeable, and respectful.
