How To Prevent Winter HVAC Issues in Maryland

There’s nothing worse than a chilly Maryland winter night with a malfunctioning HVAC system. As temperatures drop, your heating system works harder, increasing the risk of breakdowns and inefficiencies. Thankfully, you can avoid many common cold-weather HVAC problems with proactive care.

Schedule Seasonal Furnace Maintenance

Routine furnace maintenance keeps your system running safely and efficiently. A professional technician will clean components, check for gas leaks, and test carbon monoxide emissions. Skipping annual tune-ups risks uneven heating or sudden breakdowns when you need warmth the most.

Schedule a pre-winter inspection to catch minor issues early. This simple step ensures your furnace operates smoothly and reduces long-term wear.

Replace Air Filters Consistently

Clogged filters strain your system, raising energy bills and lowering air quality. Check filters monthly during the winter and replace them when dirt and dust accumulate.

Regular filter replacement protects your HVAC from dust buildup that damages internal parts. Choose high-efficiency filters for better allergen control.

Inspect and Calibrate Your Thermostat

A misaligned thermostat causes temperature swings or short-cycling. Check the batteries, ensure it’s set to “heat” mode, and consider upgrading to a smart thermostat for zoned heating.

During a thermostat inspection, a technician recalibrates sensors and tightens wiring. This ensures your furnace runs only when needed, saving energy and reducing wear.

Seal Leaky Ducts for Better Efficiency

Leaky ducts waste heated air, forcing your system to overwork. Use foil tape for temporary fixes or hire a pro for permanent duct sealing. Combined with vent cleaning, this improves airflow and lowers utility bills.

Insulate Pipes To Prevent Freezing

Unprotected pipes can burst during Maryland freezes. Pipe insulation is necessary in basements, garages, or attics using foam sleeves.

Don’t forget outdoor spigots, either. Shut off these valves and cover them with insulated caps. Letting faucets drip during extreme cold also relieves internal pipe pressure.

Clean HVAC Vents and Ensure Proper Airflow

Blocked vents strain your furnace. Move furniture or decor away from vents and vacuum dust from registers. Vent cleaning includes dryer exhausts and HVAC intakes clogged with lint or dirt.

If drafts persist, professionals can test airflow and adjust dampers for even heat distribution.

Check for Carbon Monoxide Safety

Carbon monoxide leaks are a silent threat in homes with gas furnaces. Test detectors monthly, replace batteries yearly and install units near bedrooms. Annual furnace maintenance also prevents leaks from cracked heat exchangers or flues.

If a carbon monoxide alarm sounds, evacuate your home and call emergency services immediately.
