  • What are the most common signs that my heat pump needs repair?

    The most common signs include inconsistent heating or cooling (hot and cold spots), loud or unusual noises (grinding, rattling, or screeching), a frozen outdoor unit (which may indicate a problem with the defrost cycle), and spiking energy bills. If you notice any of these issues, a professional diagnosis is required.

  • Why is my outdoor heat pump unit freezing up?

    A frozen outdoor unit is a common heat pump issue that can be caused by several factors, including low refrigerant levels, a malfunctioning defrost cycle, or poor airflow due to a dirty filter or blocked coils. Continuing to run a frozen unit can cause severe damage to the compressor, so it requires immediate professional attention.

  • How often should I have my heat pump maintained to prevent repairs?

    Because a heat pump operates year-round, it requires bi-annual maintenance: one tune-up in the spring before the cooling season and one in the fall before the heating season. This proactive care is essential for checking the dual-mode components and ensuring the system is ready for seasonal transitions.

  • Is it better to repair my heat pump or consider a replacement?

    The decision to repair or replace depends on the unit’s age and the cost of the repair. If your heat pump is over 15 years old and the repair cost exceeds 50% of the cost of a new unit, a Heat Pump Replacement is generally the more cost-effective long-term solution. Our technician will provide an honest assessment to help you decide.

  • Why does my heat pump blow cold air in the winter?

    If your heat pump is blowing cold air, it could be due to a few reasons: the system may be in a defrost cycle (which is normal and temporary), the reversing valve may be stuck, or the auxiliary heat (emergency heat) may not be engaging properly. A professional repair technician can quickly diagnose and fix the underlying cause.
