    Common Furnace Problems

    When winter weather hits, dealing with a malfunctioning furnace can be the last thing you want to deal with. Fortunately, TR Miller Heating, Cooling & Plumbing’s heating contractors are available to repair your unit and restore heat to your home.

    Call us immediately if you notice any of these common furnace problems:
    • Skipped maintenance: When is the last time your unit was inspected by an HVAC contractor? Failing to schedule regular (at least once a year) visits with a professional can lead to numerous issues with your system that should be inspected by a contractor.
    • Dirty filters: Do you change your unit’s filters every three months? Neglecting to do this can cause dust, dirt, and debris to build up, which can lead to your unit malfunctioning and reduce your indoor air quality.
    • Signs of aging: As your system ages it can experience more wear and tear that can impact the unit’s overall efficiency. As this happens you should consult a service company to determine if it is more cost-effective to replace the system.
    • Malfunctioning thermostat: If your home isn’t reaching a desirable temperature it can signal an issue with the thermostat. A professional can inspect it to determine the cause and repair the issue.
    • Inadequate airflow: Having the right amount of airflow is crucial for your unit to work properly, as disrupted airflow can cause your unit to overheat and create a dangerous situation for your family.
    • Carbon monoxide leak: One of the most dangerous issues with your unit is a carbon monoxide leak. This can put your family’s health at risk and should be addressed immediately. If the pilot light turns from blue to yellow, if you notice an excess of condensation on the windows or if anyone in your household feels ill, you should quickly call a service company and immediately evacuate your home.

    Signs Your Heater Needs to Be Replaced

    While it can seem more cost-effective to repair your heating unit rather than replacing it, there comes a point when it can be more beneficial to install a new system.

    The following symptoms can signal you should talk to an HVAC professional about if it’s time to replace your unit:
    • Your unit is older and nearing the end of its lifespan.
    • You have a cracked heat exchanger, which can create a dangerous situation for you and your family.
    • Your system is less efficient and is no longer heating your home properly or evenly.
    • Your system needs multiple or major repairs.
    • Your utility bills are rising.

    When looking for a new unit, call TR Miller Heating, Cooling & Plumbing. Our experts will help you determine which system is best for your home and will install it with expertise, giving you peace of mind.

    What to Expect During a Heater Tune-Up

    Having your heater regularly maintained can help increase its lifespan and its efficiency. It’s recommended that you schedule services at least once a year, usually in the late spring or early fall.

    During these routine inspections, heating contractors will closely examine your unit and its components. You can also expect the professional to shut off the power. This allows him or her to safely examine and work on your unit. He or she will also typically ask you if you’d like to replace any worn out parts or belts that he or she sees during the tune-up. Replacing these now will help prevent potential breakdowns during inopportune times, like the middle of winter.
