Armstrong Son Heating Air - Manteo's Licensed HVAC Services

This is often caused by a clogged condensate drain line, a very common issue in our humid coastal climate. Algae and mold can block the drain, causing water to back up. Armstrong Son Heating Air will clear the blockage, flush the line to prevent recurrence, and check the drain pan to ensure your system is draining properly and preventing water damage.

Absolutely. Dirty evaporator coils are a frequent culprit for reduced cooling and higher energy bills, especially with our sandy environment. When the coil is coated with dirt and debris, it can't absorb heat effectively. Our technicians perform thorough coil cleaning as part of our maintenance service to restore efficiency, improve cooling, and help extend the lifespan of your AC unit.

We recommend bi-annual maintenance—once in spring for your AC and once in fall for your heating system. Our local service specifically targets issues like clogged drains and dirty coils, checks refrigerant levels, cleans condenser units, and ensures all components are working correctly. This proactive care helps prevent breakdowns during peak seasons and keeps your system running efficiently year-round.
