Pasadena, CA
Air Conditioning in Pasadena: what's different
Air Conditioning work in Pasadena follows the local climate. Mixed climates get real summers and real winters, so the AC has a full season of work and then sits idle. Spring start-up problems such as weak capacitors, low charge and clogged drains are common.
A common Pasadena pattern: historic home retrofits. Craftsman homes often need ductless systems or carefully hidden ducts to add cooling without altering historic features. Another: hot summers. Long hot stretches stress older AC systems and attic ducts.
The air conditioning services Pasadena homeowners ask for most are AC Repair. Warm air, no cooling, short cycling, noises and breaker trips.
The City of Pasadena Planning and Community Development Department issues mechanical permits, and historic districts may have rules about visible outdoor equipment. California requires C-20 licensed HVAC contractors.
