Every type of air cleaner has consumable components that degrade over time. Without routine service, performance drops gradually — often without obvious signs — until the system is providing little to no meaningful air filtration.
Here's what happens when maintenance is deferred:
Clogged Media Filters
A saturated media filter doesn't just stop filtering — it restricts airflow through your entire HVAC system, forcing your furnace fan to work harder. This increases energy consumption, adds wear to your blower motor, and can eventually cause overheating. In worst-case scenarios, a completely blocked filter causes the furnace to short-cycle or fail entirely.
Dirty Electronic Collection Cells
When the collection plates in an electronic air cleaner are not cleaned regularly, particle buildup reduces the electrical charge across the cell and dramatically lowers capture efficiency. A dirty cell can also arc intermittently, producing a crackling sound and, over time, damaging the ionizing components.
Expired UV Bulbs
UV-C bulbs lose germicidal effectiveness as they age — the ultraviolet output that neutralizes bacteria and viruses diminishes steadily over 12 months, even if the bulb still appears to be glowing. A UV system running on an old bulb may look like it's working while providing no meaningful pathogen control.
Saturated Carbon Filters
Activated carbon has a finite capacity to absorb gases and odours. Once saturated, it stops adsorbing and can actually begin releasing previously captured compounds back into the air. Most carbon filters reach saturation within 3–6 months in an active household.
Our maintenance plan is designed to cover every service task your air cleaner needs to operate at rated performance throughout the year. Here is exactly what is included:
Annual System Inspection
A licensed HVAC technician visits your home once per year — or more frequently depending on your plan tier — to perform a comprehensive inspection of your entire air cleaning system. This includes the filter housing, electrical connections, control integration with your furnace or air handler, and a full performance assessment.
Filter Replacement
For media filter systems, we replace the filter media at the appropriate interval — typically every 6–12 months depending on your household's air quality demands. Filter media is included in the plan cost; no surprise parts charges.
Electronic Cell Cleaning
For electronic and electrostatic air cleaners, we clean the ionizing wires and collection plates thoroughly, inspect the cell for any signs of damage or arcing, and verify that the electrical charge is performing at specification.
UV Bulb Replacement
For UV-C germicidal systems, we replace the UV lamp on an annual basis — even if it appears to be functioning — to ensure germicidal output is maintained at rated levels. Bulb replacement is included in the plan.
Carbon Filter Replacement
For systems with activated carbon filtration layers, we replace the carbon media at the recommended interval to ensure continuous odour and VOC control. Carbon replacement is included in the plan.
Airflow and Integration Test
After every service visit, we verify that your air cleaner is operating correctly within your HVAC system — confirming that airflow is unrestricted, electrical components are functioning, and the system is communicating correctly with your thermostat or smart controls.
Priority Emergency Service
Plan members receive priority scheduling for any emergency repair calls — meaning you go to the front of the queue when you need urgent service, regardless of the time of day.
We offer maintenance plans designed to match different system types and household needs. Our team will recommend the right plan for your specific equipment during your first service visit or consultation.

Not sure how often your specific system needs servicing? Here is a quick reference guide:

Homeowners who manage their own air cleaner servicing often do so inconsistently — not because they don't care, but because life gets busy and filter change reminders are easy to ignore. Here is what that typically leads to:
- Filters run 12–24 months past their replacement date, reducing filtration to near zero
- UV bulbs operate for 2–3 years without replacement, providing no meaningful germicidal protection
- Electronic cells accumulate enough debris to cause arcing, leading to repair calls that could have been avoided
- Reduced HVAC airflow from blocked filters increases furnace energy consumption and strain on the blower motor
- Allergy and respiratory symptoms return gradually — often attributed to other causes rather than the failing air cleaner
A maintenance plan eliminates all of these outcomes. You don't need to remember — we do it for you.
We believe in giving homeowners honest information. There are maintenance tasks you can and should do yourself — and there are tasks that require a licensed technician.
Safe for Homeowners to DIY
- Washing electronic air cleaner collection plates with water (monthly or as needed)
- Checking and replacing portable air purifier pre-filters every 3 months
- Visually inspecting the filter housing for obvious blockage or damage
- Checking that the system's indicator lights are showing normal operation
Requires a Licensed HVAC Technician
- Media filter replacement in whole-home duct systems (requires correct sizing and proper seating to prevent bypass)
- UV bulb replacement (involves working inside the HVAC air handler — electrical safety risk)
- Carbon filter replacement in integrated HVAC systems (requires duct access and proper sealing)
- Electrical inspection of ionizing cells, wiring, and control boards
- Airflow measurement and system integration testing
- Any repair work on electrical components, motors, or control systems
Our maintenance plan covers all the professional tasks above, scheduled around your calendar and completed by a licensed technician — so you never have to navigate the line between what's safe to DIY and what isn't.

How much does an air cleaner maintenance plan cost in Ontario?
Plan pricing varies based on your system type and the coverage tier you select. We provide a clear, upfront quote before you enrol — no escalating fees or hidden charges. Contact us at 1 (888) 675-5907 or book a consultation and we will walk you through the options and costs for your specific system.
Do I need a maintenance plan if my air cleaner is still under warranty?
Most manufacturer warranties cover parts defects — they do not cover performance degradation caused by lack of maintenance. In fact, some warranties require documented proof of regular maintenance as a condition of coverage. A maintenance plan protects both your equipment's performance and your warranty standing.
Can I enrol in a maintenance plan after my air cleaner is already installed?
Yes. You can enrol at any time — whether you purchased your system from us or had it installed by another provider. We will start with an initial inspection and service to bring the system up to a known baseline, then put you on the regular maintenance schedule from that point forward.
How do I know when my filter needs to be replaced without a maintenance plan?
Most whole-home systems have a filter change indicator or a recommended replacement schedule in the owner's manual. As a general rule: media filters every 6–12 months, UV bulbs every 12 months, and carbon filters every 3–6 months. The challenge is that these intervals vary with usage and air quality conditions, and most homeowners lose track over time. A maintenance plan removes that variable entirely.
Does a maintenance plan cover my entire HVAC system or just the air cleaner?
Our Air Cleaner Maintenance Plan is specifically for your air cleaning equipment. We also offer broader HVAC maintenance plans that cover your furnace, air conditioner, and air cleaner as a complete system — often at better overall value. Ask our team about bundled HVAC maintenance plan options when you call.
Don't leave your family's air quality to chance. A maintenance plan from Constant Home Comfort means your air cleaner runs at peak performance all year — with no scheduling hassles, no forgotten filter changes, and no surprise breakdowns.
We serve Toronto, GTA, Hamilton, Ottawa, Barrie, London, Waterloo, Burlington, and communities across Ontario. Enrolment is simple — call us, and we'll schedule your first service visit and get you set up on the right plan for your system.
