HVAC Repair FAQs in San Mar, MD

Weak airflow usually indicates a severely clogged air filter, leaky ductwork, or a failing blower motor. This is an issue that our local experts can inspect and resolve to restore proper air circulation.
A standard replacement of an AC and furnace usually takes about 1 full day. If extensive ductwork modifications are required, the installation will take slightly longer to ensure perfect airflow.
A well-maintained air conditioning unit typically lasts 10 to 15 years, while a gas furnace can last 15 to 20 years. Regular annual tune-ups are key to maximizing the lifespan of your equipment.
A loud noise is a sign of a mechanical issue. Squealing often points to a worn-out blower motor belt, while banging could be a loose part or an ignition delay in your furnace. Local HVAC Repair Masters can quickly diagnose the root cause for you in San Mar, MD.
First, check the air filter. If it is clean, your system is likely low on refrigerant or the evaporator coil is frozen solid. Turn the AC off to prevent compressor damage, and call (877) 515-4832 so we can send a technician to San Mar, MD to inspect it.
