Your heating and cooling system can only perform as well as the home it operates in — and if your attic, walls, or crawl space are poorly insulated, you're losing a significant portion of the energy you're paying for every single month. Constant Home Comfort offers professional attic insulation and crawl space insulation upgrades that work alongside your HVAC system to dramatically reduce heat loss in winter and heat gain in summer, lowering your energy bills year-round and improving overall system efficiency. But we don't stop there. As part of Ontario's growing push toward greener homes, we also install solar panels, battery storage systems, EV chargers, and smart home electrical solutions — all of which may qualify for provincial and federal green energy incentive programs. Our team helps you understand which rebates and grants apply to your specific home and location, then manages the entire upgrade process from start to finish. Whether you're taking your first step toward energy independence with attic insulation or going all-in with solar and battery backup, Constant Home Comfort is the single provider that can handle your entire home's transformation. One company, one call, one complete solution.
Ontario's Home Renovation Savings Program — delivered by Enbridge Gas and Save on Energy — is one of the most generous home energy incentive programs in the province's history, and GTA homeowners are leaving thousands of dollars unclaimed every month. Qualifying upgrades include up to $7,500 for a cold climate air source heat pump and up to $12,000 for a ground source system, with total combined savings potentially reaching $14,000 when federal tax credits are layered in. The program is open to homeowners heated by natural gas, electricity, oil, propane, or wood — meaning most Ontario homes are eligible. Constant Home Comfort is a registered contractor approved to participate in the Home Renovation Savings Program, so we verify your eligibility, prepare your application, and submit everything on your behalf — at no extra cost to you. Whether you're upgrading a single system or planning a full home energy retrofit, we'll walk you through exactly what you qualify for before any work begins. Call 1-888-675-5907 today before funding runs out.
When your furnace or air conditioner breaks down in the middle of a Canadian winter or a sweltering GTA summer, you need a trusted local company that can respond quickly, install reliably, and price fairly — without pressuring you into equipment you don't need. Constant Home Comfort has been serving homeowners across Markham, Toronto, and the surrounding Greater Toronto Area with honest, transparent HVAC installations backed by industry-leading brands including Lennox, Goodman, KeepRite, and Gree. We source our equipment directly from suppliers and pass those savings on to you, while also layering in every applicable government grant, utility rebate, and manufacturer promotion available at the time of your installation. Our certified technicians handle everything from permits and installation to system testing and post-install support — so you're never left wondering if the job was done right. With our $0 down, 0% interest financing option available on approved credit, upgrading your home's heating and cooling system has never been more accessible. Full price disclosure from the very first conversation — no surprises on install day.
If your second floor turns into an oven every summer, or your finished basement never quite warms up in winter, you're dealing with one of the most common comfort problems in GTA homes — and a ductless mini-split heat pump is the most efficient, cost-effective solution available today. Unlike traditional forced-air systems, a ductless heat pump requires no ductwork, making it perfect for older homes, room additions, home offices, garages, and any space that your central system simply can't reach. Constant Home Comfort installs ductless systems from top-rated brands and sizes every unit precisely to the room it serves, so you get maximum efficiency without overpaying for capacity you don't need. Better yet, qualifying ductless installations in Ontario are eligible for up to $5,000 in government rebates, which we apply directly to your project cost. Our licensed GTA technicians complete most ductless installations in a single day with minimal disruption to your home, and every system comes with a full manufacturer warranty backed by our own service guarantee. Heating and cooling, solved — in one sleek, quiet, wall-mounted unit.
True home comfort goes far beyond just heating and cooling — it's the quality of the air you breathe every day, the reliability of your hot water supply, and the humidity levels that protect your family's health and your home's structure through every season. Constant Home Comfort is the GTA's one-stop provider for the full spectrum of home comfort solutions, including Rinnai tankless water heaters that deliver endless hot water on demand, Aprilaire whole-home humidifiers that prevent dry air damage in winter, and ERV/HRV ventilation systems that continuously cycle fresh, filtered air through your home without losing heat. We also carry and install certified air cleaners and purifiers that reduce allergens, dust, bacteria, and airborne contaminants — especially important for families with asthma, allergies, or young children. Every product we carry is sourced from trusted manufacturers with full warranty coverage, and every installation is completed by our own licensed Ontario technicians — not subcontractors. Whether you need a single upgrade or a complete indoor environment overhaul, we'll assess your home and recommend only what you actually need, at a price that's fully disclosed before any work begins.

Evan Li responded the same day to my request for a quote. He gave me an estimate based on the size of the room, so I could see what this project would cost. He was on site the next day, and quickly assessed what was needed, and firmed up the price. The unit was in stock so an install within 2 days was done. Installation by two very professional technicians went quickly and the Split Aircon and heat pump was running within hours. My garage/workshop space is now nice and cool. The price was very reasonable. A great experience. I highly recommend Evan Li and his team.
Excellent servicing on our rented water heater. The technician, was very professional and addressed the problems promptly — articulating the issues and how he planned to resolve them. I appreciated that he used PPE and was extremely mindful of public health requirements when entering our home. Thank you!
Booked a summer tune-up for our central air and couldn't be happier. The technician was knowledgeable, friendly, and took the time to explain what he was checking and why. Our system is running noticeably better. Constant Home Comfort has earned a loyal customer.
Our heat went out on one of the coldest nights of the year and Constant Home Comfort had a technician at our door within two hours. He diagnosed the issue quickly and had us back up and running before midnight. Incredible response time — this is a company that actually delivers on its promises.
Switched to Constant Home Comfort for our water heater rental after a frustrating experience with another provider. The switchover was seamless — they handled everything and the new unit was installed with zero fuss. The monthly rate is fair and customer support is always easy to reach. Glad we made the change.
Been using Constant Home Comfort for our annual HVAC inspection for three years running. Every technician who has come through has been professional, thorough, and respectful of our home. They caught a minor issue this year before it became a major one. That kind of proactive service is exactly what you want from a home comfort provider.
Had a smart thermostat installed last month and the difference has been remarkable — both in comfort and on our energy bill. The technician set everything up, connected it to our phone, and walked us through all the features before leaving. Quick, clean, and professional. Highly recommend!
Constant Home Comfort really delivers. The installation service was flawless—the technicians were punctual, professional, and left my home spotless.
What truly sets them apart is the education they provide; Linda’s blogs are absolutely amazing! I learned so much about maintaining my system and saving on energy costs before the team even arrived. Outstanding service paired with expert advice.
