HVAC Repair and Replacement in Ladue
Ladue sits in one of the more demanding climate pockets in the St. Louis metro. Summers push humidity past 70 percent, forcing your air conditioner to strip moisture from the air before it can actually cool your space. When refrigerant levels drop, or evaporator coils ice over, the system runs, but your home stays sticky. We check refrigerant charge with calibrated manifold gauges, clear blocked drain lines, and inspect condenser coils for debris before anything else. If full air conditioner replacement makes more sense than a repair, we run a Manual J load calculation to make sure the new unit is sized right.
Many Ladue homes run high-efficiency gas furnaces with two-stage or variable-speed blowers. Those systems need a trained eye when something fails. We pull fault codes from the control board, check heat exchanger integrity, test ignitor microamps, and verify gas pressure before diagnosing. Furnace repair calls always include a full combustion safety check. Heat pump homes, including many near Fenton and Eureka where heat pumps are especially common, get defrost cycle testing and refrigerant verification on every heating visit. From air conditioner repair to indoor air quality upgrades, we cover your full heating and cooling system.
Why Choose Aire Serv of St. Louis for HVAC in Ladue
Our locally owned team services Ladue, Town and Country, Ballwin, Manchester, Wildwood, Ellisville, and Pacific. Every price is quoted before work starts. No surprise charges after the job. Our St. Louis HVAC pros hold NATE certification and carry EPA Section 608 refrigerant credentials for both legacy R-410A systems and newer R-454B equipment.
Indoor air quality is something Ladue residents often overlook until allergy season hits. Missouri spring pollen counts spike through April and May, and the humidity that follows can push mold growth on evaporator coils. We install whole-home humidifier and dehumidifier systems, UV germicidal lamps, and media air filtration to address these problems at the source.
