How often Should You Schedule Regular Furnace & Air Conditioning Maintenance?

January 31, 2022

Heating, Ventilation, and Air Conditioning (HVAC) systems are vital for home comfort. An HVAC system heats and cools the air, but it also cleans it, controls air moisture, and removes bacteria, carbon dioxide, odours, and dust in your home. Annual maintenance or service lowers your energy consumption by 5 – 15%.

“If you feel your heating and cooling systems require replacement, we are your London and area provider for custom installations of furnaces and air conditioning.” 

Annual furnace maintenance should be done in the early fall, and air conditioning maintenance should be performed in the springtime. Regular checks prevent costly repairs in the future, keep the systems working optimally, and reduce your energy bills. 

Overheating the systems (furnace and AC) occurs when the blower motor must work harder to push air through the dust buildup in the air filter. Read tips on our Furnace Maintenance Page and Air Conditioner Maintenance Page.

Put a reminder on your phone to check and change your furnace air filter during both the cooling and heating seasons because your air conditioning unit and furnace share the use of a filter. 

Changing the air filter located in your furnace is easily done by yourself. Leaving a dirty filter affects almost every aspect of a furnace’s and air conditioner’s operations and lifespan.

  • Pay attention to the direction that you install the filter. You’ll see arrows and wording on the side of the filter to help you. The arrows point toward the motor.
  • It is optimal to change the air filter located in the furnace every 6-11 weeks during the heating and cooling seasons or wash an electrostatic filter.
  • Invest in the highest quality filters available for the make and model of your furnace. Read the model on a sticker on the side of the furnace. Not every furnace has enough blower capacity to accept a HEPA filter. Research or check with a furnace maintenance company to determine whether your furnace’s age, brand and model, and BTU capacity can handle the reduced airspeed through the tighter weave of a HEPA filter. Otherwise, you may cause the system to unfavourably overheat.

A dirty filter causes many expensive problems that can be simply solved by a fresh, very affordable air/furnace filter.  

  • The furnace blower motor can irreparably overheat.
  • It creates a lack of efficient heat exchange through the system.
  • The evaporator coil (A-coil) of your AC system becomes plugged.
  • The high-limit switch will trip continually, wearing out the furnace. It cannot correctly read the air temperature since the dirty filter, and reduced airflow creates artificial heat due to overheating.

All aspects of your furnace and air conditioning systems benefit from regular service/maintenance performed by Plumbhouse Plumbing, Heating, & Electrical. 

For early fall maintenance of your furnace, we will:

  • Change your furnace air filter (plus, we carry HEPA filters).
  • Clean and adjust the furnace pilot light.
  • Inspect the burner system. It is the component where the air mixes with your furnace’s type of fuel to create heat.
    • Inspect the primary and secondary heat exchangers. These are a series of tubes and metal containers through which flue gas moves through the system while also heating the circulating air.
    • Examine the flue pipe.
    • Lubricate all moving parts.

    For late spring maintenance of your air conditioner, we will:

    • Change your air filter.
    • Check for carbon monoxide leaks.
    • Check electrical connections.
    • Inspect the condensate drain. It can sometimes become blocked.
    • Clean and adjust the blower.
    • Look at the amount of refrigerant. Leaks can occur.
    • Lubricate all moving parts.
