A thermostat protection plan is a service agreement that covers the cost of diagnosing, repairing, or replacing your thermostat if it malfunctions or fails — without surprise bills or emergency call charges. Think of it as an extended warranty and priority service agreement combined into one.

Unlike a manufacturer's warranty — which typically covers defects in materials and workmanship for a limited period from the purchase date — a protection plan covers real-world failures that happen after the warranty period ends, including failures caused by normal wear and aging, wiring issues between the thermostat and your HVAC equipment, and the labour costs of emergency service calls. It also typically includes the priority dispatch and service response that standard out-of-warranty service does not guarantee.

Constant Home Comfort's protection plan extends beyond the thermostat itself to cover the full HVAC system it controls — because a thermostat failure and a furnace failure look identical from the homeowner's perspective until a technician diagnoses the actual source. Our plan ensures that regardless of where the problem originates, you're covered.

Thermostat Diagnosis and Repair

When your thermostat shows symptoms — a blank screen, erratic temperature readings, a system that won't respond to thermostat commands, or a smart thermostat that's persistently offline — our technicians diagnose the issue at no additional service call charge under the plan. Labour costs for covered repairs are included, and standard replacement parts required to restore your thermostat to working order are covered at preferred pricing.

Thermostat Replacement

When repair is not cost-effective — either because the thermostat has failed beyond repair or because the cost of repair approaches the cost of a new unit — our protection plan covers thermostat replacement. We supply and install a replacement unit that is compatible with your HVAC system, configure it correctly, and set up any smart features or app connectivity at no emergency labour charge to you.

Wiring and Connection Repairs

Many thermostat problems originate not in the thermostat itself but in the low-voltage wiring that connects it to your furnace or air handler — a corroded terminal, a broken wire, or a blown fuse on the furnace control board caused by a wiring short. Our protection plan covers the full diagnostic and repair process regardless of whether the fault is in the thermostat or its connected wiring, so you're never left in a grey zone between "thermostat coverage" and "furnace coverage."

Emergency After-Hours Service

Thermostat failures don't follow business hours. Our protection plan includes emergency service coverage — meaning that when your thermostat fails at 10 p.m. on a Saturday night in January, you won't pay a premium after-hours emergency call charge on top of repair costs. Plan members receive covered emergency dispatch at no additional call-out fee, 24 hours a day, 7 days a week, 365 days a year.

Priority Dispatch

During peak demand periods — the first deep freeze of the season, or the first sustained heat wave of summer — our service queues fill quickly. Protection plan members receive priority dispatch ahead of standard service call customers. In practical terms, this means a faster technician response when you need it most and when the stakes for your household are highest.

Annual Preventive Inspection

Prevention is the most cost-effective form of protection. Our plan includes an annual thermostat inspection — calibration check, wiring inspection, terminal tightening, voltage testing, and smart thermostat health review — as part of your scheduled HVAC tune-up visits. Catching a developing problem before it becomes a failure is always less disruptive and less expensive than responding to an emergency.

Smart Thermostat Configuration Support

Smart thermostats — ecobee, Google Nest, Honeywell Home — are powerful devices, but they require correct configuration to deliver their full value. Our protection plan includes configuration support: help setting up or correcting your thermostat's schedule, geofencing, remote sensors, app pairing, Wi-Fi connectivity, and utility demand response enrollment. If your smart thermostat is connected but not configured optimally, that's a covered service call.

We believe in being transparent about exclusions so there are no surprises when you need to use the plan. Standard exclusions in our thermostat protection plan include:

• Physical damage caused by accidents, misuse, or unauthorized modifications — for example, a thermostat damaged by water intrusion from a leak, or a unit that was incorrectly wired by an unlicensed individual
• Cosmetic damage that does not affect thermostat function — scratched screens, faded displays, or minor casing damage
• Thermostat upgrades requested by the homeowner when the existing unit is still functional — plan coverage applies to failures, not elective upgrades
• Failures caused by the homeowner's own HVAC equipment being incompatible with the thermostat installed — which is why we verify compatibility at installation and on any service visit
• Utility or internet service outages that affect smart thermostat connectivity — these are outside our control and are not thermostat failures

If you ever have a question about whether a specific situation is covered before calling for service, our team is happy to clarify. We'd rather answer your question upfront than create uncertainty when you're already dealing with a comfort emergency.

A thermostat protection plan delivers the most value to homeowners in specific situations. Here's who benefits most:

Homeowners With Thermostats Past Their Manufacturer Warranty

Most thermostats carry a manufacturer's warranty of 1 to 3 years. Once that expires, any failure is fully out-of-pocket. If your thermostat is more than 3 years old — which describes the vast majority of thermostats in Ontario homes — you are already beyond manufacturer coverage. A protection plan picks up exactly where the manufacturer's warranty leaves off.

Homeowners With Smart or Premium Thermostats

A premium smart thermostat — ecobee SmartThermostat Premium, Google Nest Learning Thermostat — represents a $300 to $500 investment including installation. When that unit fails outside of warranty, replacement and installation is a significant cost. A protection plan caps that exposure for a fraction of the replacement cost annually, making it straightforward financial planning for a relatively expensive piece of home equipment.

Households With Vulnerable Family Members

Households with infants, elderly residents, or family members with respiratory or cardiovascular conditions face a higher risk from temperature extremes during HVAC failures. For these households, the priority dispatch and 24/7 emergency coverage provided by a protection plan is not just financial — it's a direct safety benefit. Knowing that a technician will be dispatched immediately regardless of the time of day or day of the week provides real peace of mind.

Homeowners Who Travel or Spend Extended Time Away

If you travel frequently, own a vacation property, or spend extended time away from home during Ontario's winter months, a thermostat failure while you're away can mean frozen pipes, water damage, and a home that's been at dangerous temperatures for days before anyone notices. A protection plan combined with a smart thermostat's freeze protection alerts ensures you can authorize and schedule emergency service remotely — without navigating emergency service pricing while managing a crisis from a distance.

Homeowners With Complex HVAC Systems

Heat pumps, dual-fuel systems, multi-stage furnaces, and systems with integrated humidifiers or HRV controls are more complex to diagnose and repair than standard single-stage setups. When something goes wrong with the thermostat on a complex system, the diagnostic time alone can represent a significant service cost. A protection plan covers that diagnostic time, making complex system ownership significantly less financially unpredictable.

Let's look at what a thermostat failure actually costs without a protection plan, compared to the cost of being covered.

Scenario: Smart Thermostat Failure at 11 p.m. on a January Weekend

• After-hours emergency service call fee: $150 to $250
• Diagnostic labour (1 hour): $100 to $150
• Replacement thermostat (ecobee or Nest equivalent): $250 to $329
• Installation labour: $100 to $175
• Total out-of-pocket without a plan: $600 to $900+

A single emergency thermostat replacement event without coverage costs more than most homeowners would spend on a protection plan over several years. The plan converts that unpredictable spike into a manageable, predictable monthly cost — and covers you for every year the plan is active, not just one event.

Contact Constant Home Comfort for current protection plan pricing. Our team will outline exactly what's covered, what the annual or monthly cost is, and how the plan interacts with any existing manufacturer's warranty on your equipment.

Many homeowners assume their thermostat's manufacturer warranty provides sufficient protection. In practice, there are several important differences between a manufacturer's warranty and a service protection plan:

Duration

Manufacturer warranties typically last 1 to 3 years. A protection plan continues indefinitely as long as the plan is active — covering your thermostat through its entire useful life, not just the early years when failures are least likely.

What's Covered

Manufacturer warranties cover defects in materials and workmanship — they do not cover failures caused by normal aging, wiring issues external to the device, wear on internal components over time, or the labour cost of diagnosing a problem that turns out to originate in your HVAC system rather than the thermostat itself. A protection plan covers all of these real-world scenarios.

Labour Coverage

Most manufacturer warranties cover the cost of the replacement part — not the labour to install it. Depending on the situation, labour can be more expensive than the part itself. A protection plan covers both parts and labour for covered events.

Emergency Response

A manufacturer's warranty does not guarantee a service response time. If your thermostat fails at midnight in February and you call the manufacturer, they'll typically tell you to contact a local service provider — who will charge full emergency after-hours rates. A protection plan guarantees emergency dispatch at covered rates, with priority scheduling.

Geographic Accessibility

Manufacturer warranty claims often require contacting the manufacturer directly, shipping the device for inspection or replacement, and waiting for a resolution — sometimes weeks. A service protection plan with a local provider like Constant Home Comfort means a technician is physically at your home, often the same day, with no shipping delays and no manufacturer back-and-forth.

Enrolling in and using our protection plan is designed to be simple — because the last thing you want to do when your heat has stopped working is navigate a complicated claims process.

1. Enroll. Contact Constant Home Comfort by phone or through our website to enroll in the protection plan. We'll confirm your thermostat model, your HVAC system type, and any relevant details to ensure you're on the right coverage tier. Enrollment takes one conversation.
2. Schedule your first inspection. New plan members receive a thermostat and system inspection within the first 30 days of enrollment. This baseline inspection documents the current state of your thermostat and system and confirms everything is in proper working order at the start of your plan.
3. If something goes wrong, call us. Any time your thermostat or covered HVAC equipment shows a problem, call 1-888-675-5907 and identify yourself as a protection plan member. You'll be flagged as a priority dispatch and a technician will be scheduled immediately.
4. We diagnose, repair, or replace. Our technician arrives, diagnoses the issue, and resolves it — repair or replacement — under the terms of your plan. You're not presented with a surprise bill for covered services. Any costs outside of plan coverage are explained and approved before work begins.
5. Annual renewal. Your plan renews automatically each year. We'll contact you in advance of renewal to confirm current plan terms and pricing. You can cancel at renewal time with no penalty.

The Cost of Failure Is Higher Here

A thermostat failure in a mild climate is an inconvenience. In Toronto in January, it can become a safety issue within hours and a property damage event within days. The financial risk of a thermostat failure in Ontario — frozen pipes, emergency plumbing, damaged belongings — far exceeds the replacement cost of the thermostat itself. A protection plan that guarantees emergency response is disproportionately valuable in an Ontario climate compared to milder regions.

Peak Season Service Demand Is Real

Every HVAC service provider in Ontario — including Constant Home Comfort — experiences significant demand spikes at the start of the heating season, during sustained cold snaps, and at the start of cooling season. During these periods, homeowners without a protection plan may wait 24 to 48 hours or longer for a service call. Plan members with priority dispatch status are protected from that wait — a meaningful difference when indoor temperatures are dropping.

Ontario Energy Costs Make Efficiency Loss Expensive

Ontario electricity and natural gas rates are among the higher rates in Canada. A thermostat that's slowly drifting out of calibration — running your furnace 10 to 15 percent longer than necessary — wastes a meaningful amount of energy over an Ontario heating season. The annual inspection included in the protection plan catches calibration drift early and corrects it before it adds up to hundreds of dollars in excess energy costs.

Cottage and Secondary Property Coverage

Ontario has one of the highest concentrations of recreational properties in Canada. If you own a cottage or secondary home in Ontario — especially one that sits unoccupied for weeks or months during winter — a thermostat protection plan with remote monitoring capability (via a smart thermostat) and guaranteed emergency response gives you the ability to protect your property remotely. A frozen pipe event at an unoccupied cottage can cause tens of thousands of dollars in damage. The right thermostat, properly protected, prevents it.

Is a thermostat protection plan the same as a home warranty?

No, they are different products. A home warranty is a broad policy that covers multiple home systems and appliances — plumbing, electrical, HVAC, and more — typically purchased at the time of a home sale. Coverage is often more general, response times vary widely, and claims processes can be slow. A thermostat protection plan with Constant Home Comfort is a focused HVAC service agreement with a known local provider, guaranteed emergency response times, and a straightforward claims process. It's more specialized, more responsive, and more closely tied to your specific equipment.

Can I enroll if my thermostat is already showing problems?

You can enroll, but any pre-existing problems identified at the baseline inspection are not covered under the plan until they are repaired. In many cases, we can repair the existing issue as a standard service call at the time of enrollment — after which the repaired thermostat is fully covered under the plan going forward. Contact our team to discuss your situation and we'll outline the most practical path to getting you covered.

Does the plan cover all thermostat brands?

Our protection plan covers all major thermostat brands including ecobee, Google Nest, Honeywell Home, Lennox, Carrier, and standard programmable or manual thermostats from any manufacturer. If you have a specialty or proprietary thermostat tied to a specific HVAC system, let our team know at enrollment and we'll confirm coverage specifics for your model.

What happens if my thermostat can't be repaired and needs replacement?

If our technician determines that your thermostat cannot be economically repaired, the plan covers the labour cost of removal and installation of a replacement unit. The replacement thermostat itself is provided at our preferred pricing — significantly below standard retail. For most standard thermostats, the replacement unit cost under the plan is a small fraction of what you'd pay at a hardware store or through an emergency service call without coverage.

Does the protection plan cover my furnace and AC as well?

Our full home comfort protection plan covers your thermostat, furnace, and air conditioner under a single plan — because failures in any one of these components can look like a failure in another until a technician diagnoses the source. Ask our team about bundled coverage options that protect your entire heating and cooling system under one plan for maximum peace of mind and the best value.

Can I cancel the plan if I replace my HVAC system?

Yes. Our protection plan can be cancelled at annual renewal with no penalty. If you replace your HVAC system mid-year, contact our team — in many cases, the plan can be transferred to cover the new equipment for the remainder of the annual term. We want the plan to make sense for your situation, and we'll always work with you to ensure it does.

How is the protection plan different from the maintenance plan?

The maintenance plan focuses on preventive care — scheduled tune-up visits that keep your thermostat and HVAC system running at peak efficiency and catch developing problems early. The protection plan focuses on breakdown coverage — ensuring that when something fails unexpectedly, the repair or replacement cost is covered and emergency service is dispatched with priority. The two plans complement each other: maintenance reduces the likelihood of a failure, and protection covers you if one happens anyway. Many Constant Home Comfort customers carry both.

Don't wait for a thermostat failure in the middle of a January night to wish you had coverage. Enrolling in Constant Home Comfort's thermostat protection plan takes one phone call and gives you year-round protection, priority emergency dispatch, and the confidence that your home comfort system is backed by a team of licensed Ontario HVAC professionals.

We serve homeowners across Toronto, the GTA, Hamilton, Waterloo, London, Ottawa, Barrie, and all of Ontario. Our technicians are licensed, our pricing is transparent, and our emergency line is answered by a real person — any time of day, any day of the year.
