starting your ac in spring

Simple Steps for Starting Up Your AC Unit in the Spring

When we see the first signs of sunshine and warmer temperatures, it can be tempting to run right to the thermostat and crank up the air conditioning unit without delay. But, like stretching before a big race, you should take the time to make sure all systems are ready to go. Your AC has been sitting dormant for six to eight months after all; it definitely could use a little love and encouragement before being put to work.

Here are some items to address before starting up your A/C unit in the springtime. (We’ve also included a checklist for quick reference).

Cover the basics

First off, if you have a cover that protects the condenser unit on the outside of your house, be sure to remove it before start-up. Next, make sure the breaker on your electrical panel for AC is in the on position. Finally, make sure the electrical disconnect beside the outdoor condenser is in the ‘ON’ position. If you can’t remember or are unsure of how to do this, read this past blog.

Start with some spring cleaning

Make sure you have a clean air filter in your furnace. If your filter is dirty, airflow will be inhibited, which reduces AC efficiency and performance. (Learn more)

Next, make sure to clear the area around the condenser of debris or objects. To remove leaves and debris, you can use a garden hose to rinse off the coils of the condenser. (Our last blog tells you how.)

Vents and final housekeeping items

Onto your ventilation checklist. Make sure to open all the air supply vents in the home. Having even 20% of them closed will restrict your airflow and potentially cause an AC unit to freeze up. Next, make sure all the return vents in the home (typically located at floor level in the baseboards of your home) are clear and unobstructed.

Set your thermostat and enjoy the cool air!

Now you’re ready to set the thermostat in your home. Move the switch to ‘cool’ – and set the thermostat to the desired temperature.

Don’t forget to close all your windows when running the AC unit. If you don’t, you are wasting energy by letting cool air escape and inviting warm air in!

Keep an eye out for any issues

Last but not least, keep an eye out for any potential problems in the first two weeks. Watch for the formation of water around the furnace. Water formation could be a sign that there is an obstruction in the condensate drainage.

All things considered, prepping your AC unit for spring and summer usage should be pretty straightforward. Although it has been sitting for a while, these machines are strong, durable, and able to weather harsh conditions. However, taking that little extra time and care will ensure your unit is running smoothly and providing the cooling relief you need in those sweltering months.

If you encounter any problems, be sure to check the troubleshooting guide or contact us with any questions or concerns.

Duct Work Sanitizing

If you or your loved ones suffer from respiratory issues or allergies, or you’re concerned about the quality of the air that you are breathing, ductwork sanitizing treatments give you the reassurance that your ductwork is sterile and free of contaminants that negatively impact your respiratory and overall health.

Microban is a hospital-grade sanitizing solution, which kills 99.99% of germs, viruses, funguses, molds, and other pathogens.

We also offer Benefect, an all-natural sanitizer made from plant extracts, which also kills 99.99% of germs, viruses, funguses, and molds. ​

Dryer Vent Cleaning

Dryer fires are a top-five cause of house fires. Cleaning your dryer vent regularly greatly reduces the chance of a dryer fire, plus the following benefits:

  • Reduces clothes drying times
  • Lowers utility bills through greater efficiency
  • Extends the life span of your dryer
  • Lessens the amount of allergens in your house

Brush Cleaning Method

Our high-speed rotary brushing equipment sweeps the entire interior surface of your duct work, ensuring that all dust, debris, and pet hair are vacuumed away.

Physically cleaning the entire length of your duct work ensures that no contaminants are left behind, increasing your indoor air quality and peace of mind.

Reverse Octopus Whip Tool

The reverse octopus whip has eight 16” flexible tentacles, which whip around blasting high-pressure air in all directions as it moves through your duct work.

The tool agitates and dislodges the most hard-to-reach dust, debris, and contaminants, moving them toward our duct vacuum for collection and disposal.

Furnace Tune Up

Regular furnace tune ups are essential to maximizing the lifespan and efficiency of your furnace, so you can rely on it to keep you warm all Winter long.​

During our 30+ point inspection, we check all furnace systems to identify components that are worn out and need replacement. Replacing parts before they break — preventative maintenance — maximizes heating efficiency, avoids no-heat emergencies, and saves on costly service calls. 

Home furnaces can last for 20 years or more if well-maintained. A professional furnace tune up every two years helps to preserve your investment for decades.

A/C + High-efficiency Bypass

The secondary heat exchanger in a high-efficiency furnace or A/C coil has delicate, closely spaced fins that must be protected during your furnace and duct cleaning.

For furnaces that require a bypass, we temporarily install a filter above the heat exchanger or A/C coil, and position our duct vacuum above the filter.

This bypass procedure prevents damage by ensuring all dust and debris in your supply duct work is collected before reaching the heat exchanger or A/C coil.

Standard furnaces without A/C don’t have secondary heat exchangers or A/C coils and don’t require the bypass procedure.

Exhaust Flu Stack Cleaning

Mid-efficiency furnaces produce a sand-like, mildly-corrosive byproduct. This substance condenses in the exhaust flu stack and collects over time near the inducer/venter motor, restricting exhaust gas flow. Eventually, it enters the inducer motor and causes premature wear on the furnace.

Exhaust flu stack cleaning removes the build-up to reduce the chance of motor failure and maximize the life span of your furnace. Preventative maintenance ensures your furnace runs efficiently all Winter long — without costly no-heat emergencies. 

HRV Cleaning

In Calgary, all homes built in 2016 or later have a Heat Recovery Ventilator (HRV). Some homes built or renovated after 2013 may also have an HRV.

An HRV efficiently replaces stale indoor air with fresh outdoor air, all year round.

As with any other air-handling equipment in your home, your HRV should be cleaned regularly to ensure the best possible indoor air quality.

Not sure if you have an HRV? Call our team to find out how you can tell.

A/C Tune Up

Regular preventative maintenance improves efficiency and extends the lifespan of your air conditioning system, with the following benefits:

  • Reduced electricity bills and operating costs. When the unit operates as designed, electricity usage is reduced.
  • Maximized cooling capacity. Home comfort on the hottest of days with minimum run time.
  • Minimized repair bills. Detect and fix small problems before they get worse.

Hot water tank types

Natural draft or atmospheric vented hot water tanks have a 3″ – 4″ steel vent pipe, which runs to a vertical chimney. The chimney is usually shared with standard or mid-efficiency furnaces.

Power vented hot water tanks have one or two black or white plastic vent pipe(s), which are 2″ – 3″ in diameter. The vent pipes usually exit from the side of the house.

Back Skipper Tool

The back skipper is a 1” diameter rounded ball connected to a long, flexible high-pressure airline.

The 1” ball has jets that discharge high-pressure air, pulling the tool and airline through the length of your duct work.

The high-pressure air moves the dust and debris toward our duct vacuum, where it is collected for disposal.​
