At the beginning and end of each cooling season, there are specific things you need to do before you switch on your air conditioner for the first time, as well as after you stop using it in the fall. In Calgary, some of the hottest summer weather homeowners experience is from July through September. Although, it is not uncommon to have several warmer days with record high temperatures in May and June, too.
At Distinct Heating & Cooling, we have prepared a checklist for you to use in the Spring and Fall to help you start up and shut down your air conditioner system correctly. We recommend reviewing this list to avoid potential problems now and in the future, not to mention unexpected and often costly repairs. In the event you require assistance with completing the checklist, do not hesitate to contact one of our qualified Calgary air conditioner service technicians to provide help and ensure your air conditioner system is running efficiently and correctly at the start of the season.
Common Air Conditioner System Definitions
Before discussing the proper way to start up or shut down the A/C system, we have provided a list of common A/C system definitions to better enable you to identify specific areas of the system that require your attention during these processes.
The same air filter used with your furnace is also used as part of the cooling system. All of the air that moves throughout the ductwork and ventilation system within your Calgary home travels through the same system. It is important to change the air filter on a regular basis to prevent dust, dirt, allergens, pet dander, pet hair, and other particles from getting into the system and creating operational problems.
Air Conditioner Condensing Coil
The condensing coil is the exterior part of the outside A/C unit. The coil can become clogged with dirt, dust, pollen, and other debris, which results in reduced airflow, problems with the coil’s ability to absorb heat, and a decrease in the efficiency of the cooling system. The condensing coil can easily be damaged and bent, so it is highly recommended to schedule professional air conditioner maintenance service in Calgary to clean them when they are dirty or clogged.
Air Conditioner Evaporator Coil
The evaporator coil is typically the indoor part of the A/C unit. This coil can also get dirty from any dust, pollen, or debris that is sucked into the unit or through a dirty or clogged air filter. Just like the condensing coil, dirt on the evaporate coil causes problems with the coil’s ability to absorb heat. For peak operating performance, the evaporator coil should be inspected annually and cleaned as needed by a qualified A/C technician.
Air Conditioner Cover
Some people cover their outdoor A/C units using an approved cover in the fall when they shut the system down for the season. Before turning on the system in the spring, remember to remove the cover, otherwise the system can overheat, be damaged, and result in a costly repair.
Air Conditioner System Obstructions
There are all sorts of obstructions which can hinder the operation of the A/C system. It is essential to remove any debris, foliage, overhanging tree branches, or other such obstructions from around the outdoor A/C unit. There should be a minimum of at least half a meter of clearance completely around the unit for proper air flow.
Spring Air Conditioner Start Up
When the colder winter and spring months are coming to the end, the following instructions provide an overview of what you need to do to properly and correctly start up your air conditioning system.
If you did not get your annual heating and cooling maintenance and tune-up completed last fall, the spring is a great time to get this service performed to ensure your heating system is properly shut down, your cooling system is ready to go, and there are no potential problems. Discovering and identifying operating issues now is often less costly to repair and will help avoid unexpected problems later, especially on those hot summer days.
Fall Air Conditioner Shut Down
Once late September or October arrives, and the weather starts turning colder, it is time to shut down your air conditioner system for the season and prepare your heating system. Taking the time to correctly shut down the A/C system helps keep your system operating at peak performance come next Spring.
Before fully shutting down the air conditioner system for the season, it does not hurt to do an initial start up the heating system to verify it is working correctly. Simply turn the setting on the thermostat to the “HEAT” position and adjust the temperature until the system turns on. Keep in mind, there can be minor burning smell the first time you turn on the heating system, as it burns any dust that made its way inside the furnace.
If the burning smell is stronger or does not seem to dissipate as the system blows warm air out the vents, shut the system down immediately and call for service, as this often indicates a problem with the heating system.
In addition, if you did not get your annual heating and cooling maintenance and tune-up service completed in the Spring, remember to schedule this essential service now before the colder winter months arrive. At Distinct Heating & Cooling, our 30-point heating and cooling system maintenance and tune-up provides a detailed inspection to ensure the efficient operation of your furnace and air conditioner system and avoid costly repairs later.
