Columbia, NC HVAC Repair & Air Duct Cleaning | Armstrong & Son

Regular duct cleaning is especially important in our coastal climate, where high humidity can promote mold and mildew growth within your ductwork. This buildup forces your HVAC system to work harder, reducing efficiency and circulating allergens. Our thorough cleaning service removes these contaminants, helping your system run more efficiently, improving your indoor air quality, and protecting your family's health.

First, check your home's circuit breaker to ensure power is reaching the unit. If that's not the issue, give us a call. With over 20 years of experience in HVAC system repair, our technicians can quickly diagnose the problem, whether it's a faulty component, refrigerant issue, or electrical fault. We provide clear explanations and upfront pricing for all repairs to get your Columbia home comfortable again as soon as possible.

The coastal environment can lead to faster corrosion of your condenser unit. We recommend annual professional maintenance, where our technicians will clean the coils, check for early signs of rust, and apply protective coatings if needed. We also advise keeping the area around the unit clear of vegetation and rinsing it gently with a hose periodically to remove salt spray and debris, which helps extend its lifespan significantly.
