Heat pumps are a popular choice for homeowners in Southwestern Ontario as they provide heating and cooling in one system. However, heat pumps can sometimes experience issues or break down entirely like any other appliance. That’s where Aire One Heating & Cooling KW comes in. With years of experience and a team of skilled technicians, we proudly offer comprehensive repair services for all types of heat pumps. Contact us today to get your system back up and running immediately.

Here are some common heat pump issues:
  • Refrigerant leaks: Refrigerant is crucial for heating and cooling in a heat pump system. The system won’t maintain the desired temperature if the refrigerant level drops due to a leak.

  • Faulty compressor contactor: The compressor contactor controls power to the compressor and outdoor fan on a heat pump. If the compressor contactor is damaged, the heat pump may run continuously.

  • Broken reversing valve: The reversing valve enables the heat pump to function as a heater and an air conditioner. If the reversing valve malfunctions, the heat pump will produce only cold or hot air.

  • Damaged start capacitator: If you hear a faint clicking noise when the heat pump is supposed to turn on, you probably have a problem with the start capacitor. This can cause your heat pump to work intermittently or not at all.


Even the most reliable heat pumps can experience problems. Here are some common signs your heat pump requires repairs:

  • It won’t turn on

  • It cycles on and off frequently

  • It makes strange noises

  • Your energy bills have suddenly increased

  • It struggles to keep your home at the right temperature

  • It emits strange odours

If you notice these signs, call an Aire One KW technician to diagnose the issue immediately and provide the necessary repairs.


The decision to repair or replace your heat pump depends on several factors, including the age of your current unit, the cost of the repairs and your overall budget. It’s always a good idea to consult with a professional HVAC technician to get their expert opinion before making a final decision.

  • How often should I service my boiler?
    A minimum of once a year is recommended. Heating systems come on an average of 3-8 times per hour during the heating season, these numbers can change dramatically in different style of homes and with different thermostats, but this is a rule of thumb in our industry. There is a lot of wear and tear on the appliance and setting can go out of calibration. Also, it is a requirement by most manufacturers and home insurance companies.
  • Can I add new zones to my existing boiler heating system?
    It depends if the btu output of the radiators has reached the maximum btu output the boiler can support. Having a professional to come out and calculate is your best bet.
  • How will I know if the boiler I select will work properly for my home?
    Each room will have a radiator and every radiator has a specific btu output . We calculate the total of the radiator btu outputs, match that with a heat loss/heat gain calculation for the home and that is how we size a boiler system for your home.
  • How does a boiler work to heat my home?
    A boiler is a device that heats water and then distributes the hot water throughout your home to warm the indoor air. There are two main types of boilers: hot water boilers and steam boilers. Hot water boilers heat water to a temperature of about 82 C. The hot water is then circulated through a system of pipes and radiators throughout the home. The radiators give off heat to the surrounding air, which warms the home. Steam boilers heat water to a temperature of about 100 C, which is the boiling point of water. The steam is then distributed through a system of pipes and radiators throughout the home. The steam condenses back to water on the radiators, which gives off heat to the surrounding air, warming the home. In both hot water and steam boilers, the water in the pipes cools and returns to the boiler after heating the interior spaces. The water is then reheated and recirculated throughout the home. Some boiler models also double as a water heater, eliminating the need for a separate water heater unit. The efficiency of a boiler is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. The AFUE rating is a percentage of the fuel that’s used to heat the water that heats the home. The higher the AFUE rating, the more efficient the boiler. Boilers with medium levels of efficiency have ratings of 90 to 93 per cent.
  • What is the average lifespan of a residential boiler?
    The typical residential boiler can last between 15 and 20 years. You can find the year your boiler was manufactured by checking the unit’s rating plate. You can also call the manufacturer and give them the unit’s serial number to find out how old your boiler is. If your boiler unit is more than 15 years old, you should consider replacing it with a new boiler, high-efficiency gas furnace or heat pump.
  • Are there any government rebates available for my boiler upgrade?
    Unfortunately, Ontario homeowners in the Tri-Cities area wanting to invest in a new boiler system for their homes aren’t eligible for rebates under the Home Efficiency Rebate Plus (HER+) program. Heat pumps are the only home heating system covered under HER+, whereby homeowners can get more than $10,000 in rebates on a heat pump installation. This program combines the Enbridge Gas rebate program and the Canada Greener Homes Grant.
