    Essential December Guide for Homeowners in the Pittsburgh Area

    December is here, bringing frigid temperatures that rigorously test your HVAC system. A reliable heating system isn't a luxury—it's a necessity.


    At MRT HVAC Contracting, we believe proactive care is key to avoiding costly emergencies. Here are 5 essential steps, drawn from our 30+ years of experience, to ensure your home stays warm, safe, and efficient this winter.


    1. Preventive Maintenance: The Ultimate Winter Shield

    The number one cause of winter heating failures is undetected wear and tear.

    • Your December Action: If you haven't done so, schedule a Professional Annual Inspection. A certified technician will check every core component to ensure peak performance and safety.

    The Key Fact: A well-maintained heating system can boost its energy efficiency by up to 10%, leading to significant savings on your utility bills.


    2. The Filter Swap: Your System’s Vital Breath

    The quality of the air you breathe and your heating system's efficiency depend on the air filter.

    • The Easy Task: Inspect and replace your air filter every 30 to 90 days.

    • Why It's Critical: A clogged filter forces your furnace or boiler to work harder to circulate air, increasing energy consumption and accelerating equipment wear.


    3. Optimizing Your Smart Thermostat

    If you own a smart thermostat, you can minimize energy waste by optimizing its schedule.

    • The Perfect Setting: Program your thermostat to reduce the temperature by 7°C to 10°C (or 13°F to 18°F) overnight or when your home is vacant.

    • The Scientific Benefit: You can save up to 10% on heating costs by adjusting the temperature during these unoccupied periods.


    4. Clear the Area Around the Outdoor Unit

    If you utilize a heat pump, snow and debris are its primary enemies.

    • Practical Action: Ensure the outdoor unit is clear of leaves, dirt, and especially snow and ice. The unit requires constant, unrestricted airflow to function correctly.

    A Word of Caution: If heavy ice forms, never use sharp objects. Call a professional to prevent damage.


    5. Listen and React: Warning Signs

    Your heating system typically warns you before a complete failure.

    • Abnormal or Persistent Noises: Banging, squealing, or a loud clicking can signal mechanical wear or loose components. If you suspect an issue, addressing it quickly can save you money. Learn more about proactive care on our Heating Maintenance Services page to keep your system in top shape.

    • Odors: If you smell gas, evacuate the property immediately and call the gas company. Persistent burning odors, beyond initial start-up dust, could signal an electrical issue.

    • Short Cycling: If the system turns on and off rapidly without adequately heating your home, it is severely stressed, and a total breakdown is imminent.
