Most air handler breakdowns are preventable. The components that fail most often — blower motors, capacitors, clogged coils, blocked drains — all show early warning signs that a trained technician will catch during a routine inspection, long before they become an emergency repair. The difference between a $150 tune-up and a $1,200 emergency call is often nothing more than whether a maintenance visit happened that year.

Constant Home Comfort’s air handler maintenance plans are designed for Ontario homeowners who want the confidence of knowing their system has been professionally inspected, cleaned, and optimized — every year, without having to remember to book it.

Air handlers work hard. In a typical Ontario home, your air handler runs for thousands of hours per year — moving air through heating season, cooling season, and everything in between. That level of continuous operation accumulates wear, dust, and stress on every internal component.

Here is what happens when maintenance is skipped:

• Efficiency drops: A dirty evaporator coil, clogged filter, or restricted airflow forces your system to work harder to achieve the same output. Studies consistently show that an unmaintained HVAC system can lose 5 to 15 percent of its efficiency annually — which shows up directly on your energy bill.
• Breakdowns become more frequent: Small issues — a capacitor showing signs of wear, a drain line beginning to clog, a blower bearing running dry — are invisible to the homeowner but obvious to a trained technician. Left unchecked, they become emergency failures.
• Warranties may be voided: Many manufacturer warranties require documented evidence of annual professional maintenance. Skipping service can leave you without coverage on a component that would otherwise have been replaced at no cost.
• Lifespan shortens: A well-maintained air handler routinely lasts 15 to 20 years. A neglected unit may need replacement at 8 to 10 years. The cost of premature replacement far exceeds the cost of consistent maintenance.
• Indoor air quality suffers: A dirty coil, contaminated drain pan, or degraded filter allows dust, mould, and allergens to circulate through your home. Annual cleaning directly improves the air your family breathes every day.

Our certified technicians perform a comprehensive inspection and service of your air handler and connected system during every maintenance visit. Here is exactly what we do:

Blower Assembly

• Inspect and clean the blower wheel and housing
• Check blower motor amperage and operation
• Lubricate motor bearings where applicable
• Inspect drive belt for wear or cracking (where applicable)
• Test blower motor capacitor and replace if showing signs of failure

Evaporator Coil

• Visually inspect coil for dirt, debris, and damage
• Clean accessible coil surfaces to restore heat transfer efficiency
• Check for signs of refrigerant leaks at the coil
• Inspect coil fins and straighten if bent

Condensate System

• Flush condensate drain line to clear algae and debris buildup
• Inspect drain pan for cracks, corrosion, or standing water
• Test condensate float switch where installed
• Confirm proper drainage flow and drainage path

Air Filter

• Inspect current filter condition and replace if required (standard filters)
• Advise on correct filter size and MERV rating for your system
• Check filter housing seal for bypass gaps that allow unfiltered air

Electrical Components

• Inspect all electrical connections for looseness, corrosion, or signs of arcing
• Test capacitors and contactors
• Check control board for fault codes or visible damage
• Verify thermostat communication and system response
• Inspect wiring insulation for wear

Refrigerant System (for systems connected to heat pump or AC)

• Check operating pressures against manufacturer specifications
• Inspect refrigerant lines for signs of oil staining or leaks
• Verify superheat and subcooling readings are within range
• Document refrigerant charge status

Overall System Performance

• Measure supply and return air temperatures
• Check static pressure across the air handler
• Verify airflow is balanced across zones (where applicable)
• Document all findings and provide a written service report
• Identify any items requiring attention before the next service visit

At the end of every visit, your technician will walk you through the findings, answer your questions, and provide honest guidance on anything that may need attention — with no pressure to act immediately unless there is a safety or reliability concern.

Constant Home Comfort offers maintenance and protection plan options to suit different homeowner needs. The right plan depends on the age of your equipment, how much repair coverage you want, and your preference for predictable annual costs versus pay-as-you-go service.

Annual professional maintenance keeps your system in peak condition, but there are simple tasks homeowners can and should handle between visits to protect their investment:

Monthly

• Check your air filter — hold it up to the light. If you cannot see light through it, replace it. A clogged filter is the single most common cause of avoidable air handler problems.
• Listen for any new or unusual sounds when the system is running. Anything that wasn’t there last month is worth noting and reporting.
• Ensure all supply and return vents in your home are open and unobstructed by furniture, rugs, or curtains.

Every 1 to 3 Months

• Replace standard 1-inch air filters. Households with pets, allergy sufferers, or recent renovation work may need more frequent changes.
• Check the area around the indoor unit for any signs of moisture or condensation that was not there before.
• Confirm your thermostat is reading and responding correctly.

Every 6 to 12 Months

• Replace high-capacity 4 to 5 inch media filters according to manufacturer guidelines.
• Clear any debris, vegetation, or obstructions from around your outdoor unit.
• Test your thermostat’s programming and confirm seasonal settings are correct before the heating or cooling season begins.

Annually (Professional)

• Schedule your professional maintenance visit. Ideally before the heating season begins (September–October) or before the cooling season (April–May).
• Have your ductwork inspected if you have noticed significant dust accumulation, hot or cold spots, or declining air quality.

A quick note on filters: using a filter with a MERV rating that is too high for your system can restrict airflow just as much as a dirty filter. Our technicians will confirm the right filter specification for your air handler during the maintenance visit.

Timing your annual maintenance visit correctly maximizes its benefit. In Ontario’s climate, we recommend the following schedule:

Plan members receive priority scheduling, which means you can lock in your preferred appointment time well in advance — before the spring and fall rush when every other homeowner is booking at the same time.

If you notice any of the following, do not wait for your scheduled visit. Call us to book an immediate diagnostic appointment:

• Your energy bills have increased noticeably with no change in usage habits
• There is reduced airflow from your vents compared to previous seasons
• Your home takes noticeably longer to reach the temperature set on the thermostat
• You can see visible dust buildup around supply vents
• There is a musty, mouldy, or burning smell when the system runs
• The system is short-cycling — turning on and off more frequently than it used to
• You hear sounds from the unit that are new or have changed in character
• You notice water or moisture near the indoor unit

Any of these symptoms indicate that something inside the system is working harder than it should, or has already begun to fail. Early intervention is almost always less expensive than waiting.

It can be tempting to put off a maintenance visit when your system seems to be running fine. Here is what that decision typically costs Ontario homeowners over time:

The annual cost of a professional maintenance visit is a fraction of the cost of a single emergency repair call — and a very small fraction of the cost of premature equipment replacement.

A maintenance plan is a smart investment for almost any homeowner, but it delivers the most value for:

• Homeowners with systems 5 years or older: As air handlers age, the likelihood of component wear increases. Annual professional inspection catches aging parts before they cause failures.
• Households with allergy sufferers or respiratory sensitivities: Clean coils, fresh filters, and a clear drain pan directly improve the quality of air circulating through your home.
• Homeowners who want predictable comfort costs: A maintenance plan converts unpredictable repair events into a known annual expense, making household budgeting simpler.
• Anyone who has experienced an air handler breakdown before: Once you’ve dealt with an emergency repair — especially in the middle of winter — the value of prevention is immediately clear.
• Homeowners with newer high-efficiency systems: Protecting a premium investment with annual maintenance ensures it delivers on its efficiency ratings and warranty for the full expected lifespan.
• Rental property owners: A documented maintenance record protects you as a landlord, keeps tenants comfortable, and reduces the likelihood of disruptive emergency calls.

• Certified HVAC technicians: Every maintenance visit is performed by a fully licensed, insured technician with hands-on experience across all major air handler brands and configurations.
• Comprehensive service, not a quick check: Our maintenance visits cover every component of your air handler system, not just the items that are fastest to inspect. We document everything.
• Written service report every visit: After every visit you receive a written record of what was inspected, what was found, and what was done. This documentation supports your manufacturer warranty and gives you a clear picture of your equipment’s condition over time.
• No-pressure recommendations: If we find something during a maintenance visit, we tell you about it honestly and explain your options. We will never recommend a repair or replacement you do not need.
• Priority scheduling for plan members: Plan members are scheduled first during the busy spring and fall seasons when demand for service appointments is highest.
• 24/7 support: Even between scheduled maintenance visits, our service line is available around the clock if something unexpected happens.
• Top-rated across Ontario: Consistently recognized on BBB, HomeStars, Google, and ReviewBuzz as one of Ontario’s most trusted HVAC service providers.

How often should an air handler be professionally serviced?

For most Ontario homes, once per year is the minimum recommended frequency. Older systems, systems that run year-round, or systems in homes with pets or allergy sufferers benefit from twice-yearly service — once before heating season and once before cooling season. Our technicians will recommend the right schedule for your specific equipment and usage.

What is the difference between a maintenance plan and a protection plan?

A maintenance plan covers the annual professional service visit — inspection, cleaning, and tune-up. A protection plan builds on this by also covering the cost of parts and labour on repair calls throughout the year, giving you full cost predictability and eliminating unexpected repair expenses. Protection plans are particularly valuable for systems that are 10 years or older.

Will regular maintenance actually extend the life of my air handler?

Yes, measurably. Industry data consistently shows that professionally maintained HVAC equipment lasts significantly longer than neglected units. The difference between a system that lasts 10 years and one that lasts 18 to 20 years is often primarily a function of how consistently it was maintained. Given the cost of equipment replacement, even a few additional years of service life represents significant savings.

Can I sign up for a maintenance plan if I did not buy my system from Constant Home Comfort?

Yes. Our maintenance plans are available to all Ontario homeowners regardless of who originally installed your system or which brand you own. Our technicians are experienced with all major makes and models.

What happens if the technician finds a problem during the maintenance visit?

Your technician will document the finding, explain what it means in plain language, and provide you with a written quote for any recommended repair. You are never obligated to proceed immediately — we will tell you whether the issue is urgent or can be monitored. If you are on a protection plan, parts and labour on covered repairs are included.

Does my manufacturer warranty require annual maintenance?

Many manufacturers require documented evidence of annual professional maintenance to keep the full warranty valid. Skipping service could void coverage on parts that would otherwise be replaced at no cost. Our written service reports provide the documentation your warranty requires.

How do I sign up for a maintenance plan?

Call us at 1-888-675-5907 and a member of our team will walk you through the plan options, confirm your system details, and schedule your first visit. Setup takes just a few minutes and you’ll receive confirmation of your plan and first appointment before you hang up.

Can a maintenance plan be cancelled?

Yes. Our maintenance plans are not long-term lock-in contracts. If your circumstances change, you can cancel with appropriate notice as outlined in your plan agreement. We will always be clear about the terms before you sign up.

Do not wait until something goes wrong. A single professional maintenance visit can prevent the most common and costly air handler failures — and give you the confidence that your system is ready for whatever Ontario’s seasons bring.

Call 1-888-675-5907 to book a visit or ask about our maintenance and protection plan options. Our team is available 24 hours a day, 7 days a week.
