Heating FAQs

  • What are the signs that my heating system needs repairs?

    Keep an eye out for unusual noises, inconsistent temperatures, frequent cycling on and off, and poor air quality. If your system is not heating your home properly, it's best to have it inspected.

  • How often does my heating system need to be serviced?

    It's recommended to have your heating system professionally inspected and serviced at least once a year, ideally before the start of the colder months. This will ensure that it operates efficiently and safely over winter.

  • Why is my heating system blowing cold air?

    This could be due to a variety of reasons, including a malfunctioning thermostat, a dirty air filter, or a heating element issue. A professional technician can diagnose and resolve the problem for you.

  • What size heater do I need for my home?

    The size of the heater you need depends on the square footage of your home, insulation quality, and climate. A technician can perform a load calculation to recommend the right size system for optimal performance.

  • What is the difference between a heat pump and a furnace?

    A furnace utilizes fuel to generate heat, while a heat pump extracts heat from the air or ground and transfers it indoors. Heat pumps are more energy-efficient but may struggle in extremely cold weather.

Cooling and AC FAQs

  • Why is my air conditioner not cooling properly?

    This could be due to a clogged air filter, blocked vents, low refrigerant levels, or a damaged broken compressor. A professional inspection will be necessary to determine the exact cause and fix the issue.

  • How often should I replace my AC unit’s air filter?

    You should check and replace your air filter every 1-3 months, depending on usage and environmental factors. A dirty air filter will reduce airflow and system efficiency.

  • What are some of the benefits of regular AC maintenance?

    Regular maintenance helps extend your AC system’s life, ensure it runs efficiently, and prevent costly repairs by addressing small issues before they become bigger problems.

  • How do I know if my air conditioning unit needs refrigerant?

    If your air conditioner is blowing warm air, has reduced cooling capacity, or you notice ice forming on the evaporator coil, it may be time for a refrigerant recharge. A technician can check the levels and refill if necessary.

  • How big does an air conditioner need to be for my home?

    The size of the AC unit required depends on a variety of factors, including the size of your home, the number of rooms, insulation, and climate. An HVAC professional can perform a load calculation to recommend the right size unit for efficient cooling.
