Air Conditioning in St. Louis: what's different
Air Conditioning work in St. Louis 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 St. Louis pattern: humidity. Humid summers stress AC systems. Another: brick home heat retention. Thick brick walls hold summer heat into the evening, so cooling systems need to be sized for long cooling periods.
The air conditioning services St. Louis homeowners ask for most are AC Repair. Warm air, no cooling, short cycling, noises and breaker trips.
The City of St. Louis Building Division issues mechanical permits in the city, and St. Louis County and its municipalities handle their own. Schedule furnace or boiler service in fall and AC service in spring.
