Technician servicing heat pump



Your heat pump works hard to keep your home comfortable year-round. But, like any other appliance, it needs proper maintenance to function at its best.

We provide a range of protection plans to fit your needs and budget.

Regular maintenance keeps your heat pump running smoothly and avoids costly repairs and replacements. Heat pumps should have routine maintenance completed at least once per year. Ideally, for extra care, you should schedule maintenance twice yearly: before summer and before winter. This ensures your system is prepared for the increased workload during these times of year.

Here are three good reasons to invest in routine maintenance with Aire One Heating & Cooling KW:
  • Enhanced performance: Regular maintenance ensures your heat pump always operates at peak efficiency. This helps reduce your energy consumption and improves your indoor comfort.

  • Extended lifespan: Ongoing maintenance can significantly extend the lifespan of your heat pump, protecting your investment and saving you money on premature replacement.

  • Improved energy efficiency: When your heat pump is well-maintained, it operates efficiently, lowering energy consumption and utility bills.

With regular maintenance, you can rest assured that your heat pump will continue providing reliable heating and cooling for years.


These parts of your heat pump require regular attention to prevent breakdowns and ensure efficient operation:

  • Filters: The air filters in your ductless heat pump should be cleaned every six months — more frequently if you smoke, have pets or just completed a home renovation. Dirty filters can restrict airflow and reduce system efficiency, leading to higher energy bills and potential breakdowns.

  • Refrigerant: Low refrigerant levels can cause a decrease in the cooling or heating capacity of your heat pump, which can lead to poor performance. It’s a good idea to have a professional periodically inspect your system to help identify leaks or deficiencies and, if necessary, recharge the refrigerant to optimize your heat pump’s performance.

  • Reversing valve: The reversing valve is an essential component that allows your heat pump to switch between heating and cooling modes. If the reversing valve becomes stuck or fails, your heat pump may not adequately heat or cool your home.

  • Compressor: The compressor is the heart of your heat pump. It’s responsible for compressing the refrigerant to produce warm or cool air. If the compressor fails, it can cause the entire system to malfunction.

  • Fan and motor bearings: Periodically lubricating your heat pump’s motor and fan bearings reduces friction and minimizes wear and tear for smooth operation. You should also regularly inspect and clean the fan blades to remove dirt or debris that could obstruct airflow.

  • 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.


Regular heat pump maintenance is a small investment that significantly pays off. From improved performance to increased longevity, taking care of your heat pump ensures comfort and peace of mind.
