  • Two-Stage Gas Valve: Operates on "low" heat about 90% of the time for quieter, more consistent comfort and switches to "high" only when the Ontario cold hits its peak.

  • Variable 25-Speed ECM Blower: A constant-torque motor that automatically adjusts airflow to meet your home's exact needs, improving dehumidification and reducing noise.

  • InteliSense™ Technology: When paired with an ecobee for Carrier thermostat, this furnace shares performance data with us for "Smart Service"—we can often diagnose issues before you notice the cold.

  • Comfort Heat Technology®: Intelligently stages heat to remove air stratification (hot/cold spots) between and within rooms.

  • Fully Insulated Casing: Includes the blower section to ensure "quieter than a conversation" operation and minimal heat loss through the cabinet.

Frequently Asked Questions

The 96.5% AFUE (Annual Fuel Utilization Efficiency) rating means that 96.5 cents of every dollar you spend on gas goes directly into heating your home. This leads to significantly lower monthly utility bills compared to older 80% AFUE "builder grade" furnaces.

Carrier invented modern air conditioning and has been a leader in heating technology for over a century. In the GTA, Carrier is prized for its reliability in extreme cold and its extensive parts network, ensuring that if you ever need a repair, parts are readily available in Ontario.

While both are high-efficiency, the Performance 59TP6 features a two-stage gas valve and a variable-speed blower, whereas the Comfort series is typically single-stage. The 59TP6 provides much more consistent temperatures and better humidity control.

It depends on your home's square footage, insulation quality, and window efficiency. Generally, 40K is for small bungalows/condos, 60K-80K for average semi or detached homes, and 100K+ for large residences. 4Most Energy provides a professional heat-loss calculation to ensure the perfect fit.

Currently, a standalone furnace installation typically does not qualify for primary rebates. However, when matched and bundled with a qualified Heat Pump as part of a Hybrid Heat™ system, it becomes eligible for significant decarbonization rebates. The goal of these incentives is to reduce your carbon footprint as much as possible—speak with our furnace experts today for the latest news on active rebate programs.

Absolutely. Beyond the Carrier manufacturer warranty, 4Most Energy provides a 1-Year Labor Warranty and a 100% Customer Satisfaction Warranty on the craftsmanship of the installation.

The 59TP6 features advanced InteliSense™ technology and a two-stage valve that requires precise calibration. A factory-trained expert from 4Most Energy knows the "fine-tuning" required to ensure you get the full 96.5% efficiency the unit is capable of.

A standard replacement usually takes 4 to 8 hours. We arrive in the morning and ensure your heat is back on and tested before we leave the same day.

Yes, we offer flexible financing options to help make a high-efficiency upgrade affordable for any budget. This allows you to pay for the system using the money you save on your lower monthly gas bills.

Renting often results in paying 3-4 times the cost of the furnace over its lifetime with difficult-to-break contracts. Financing through 4Most Energy allows you to own your equipment, build home equity, and pay it off at your own pace without predatory terms.

With over 15 years of specialized experience in the Greater Toronto Area and Southern Ontario, we have built a reputation for quality and transparency backed by hundreds of 5-star reviews. Our TSSA-certified team is factory-trained specifically for Carrier systems and committed to using only premium installation materials. We provide upfront, transparent pricing with no hidden fees, and we don't just install equipment—we provide long-term comfort support and expert maintenance.

In many cases, yes. We understand that a broken furnace in an Ontario winter is an emergency. We keep a local stock of Carrier Performance units to provide the fastest possible turnaround for our neighbors in the GTA.

We had a great experience with Rey and his team during our new Rinnai boiler installation. The technicians did an amazing job and worked efficiently. The technician Sam was knowledgeable, professional, and respectful throughout the installation. He took the time to answer all my questions and made sure everything was properly checked before finishing the job. They arrived on time and completed the boiler installation on schedule. We are very happy with the service and would definitely recommend them to anyone looking for reliable and professional HVAC service. Thanks.

I was very pleased with the competitive pricing I got specifically from 4most energy. I contacted many companies to get their best quote. Sometimes there are even daughter or sister companies that will give you better quotes than the parent companies. It's best to check around for the identical product with installation from many companies. I was also pleased with the installers. They did have to cut away some insulation to install the Rinnai RX199 on the outside wall the house. Not sure if they should have tried replacing that insulation afterwards, but won't complain about the job they did because I think I got the best price on the market after getting quotes from about a dozen companies.

We recently had a Navien Combi boiler installed by 4Most Energy and had a great experience from start to finish. Rey was our sales representative and Sam was our technician, and both were excellent to work with. They arrived on time, the installation was fast and efficient, and everyone was friendly and professional throughout the process. Sam did a great job with the installation, and everything is working perfectly. We’re also very happy with the Navien Combi boiler itself. Overall, we couldn’t be happier with the service, the installation, and the product. We would definitely recommend 4Most Energy.

I contacted 4Most Energy to replace my 14 year old AC unit. Their intake process was smooth. They provided a reasonable quote the same day. The installation of the new AC unit was scheduled and the service provided by Farzad and his associate was completed within a reasonable time. They did a great job on the installation, hauled away the old equipment, and left the job site (both indoors and outdoors) in good condition. I would not hesitate to recommend 4Most Energy for your heating and cooling needs.

Great job Rey, Sam and team! My tankless water heater was broken for two months and after getting the run around from Enercare and Reliance, I decided on purchasing a Navien from 4Most Energy and they did a great job explaining the process and installing it the next day. Thank you for the top notch service!

We had a great experience with this company when they installed our new water heater. The work was completed quickly, professionally, and with great attention to detail. We especially appreciated that they put down carpets to protect our floors and kept everything clean throughout the installation. The team was courteous, efficient, and clearly took pride in their work. We would definitely recommend them to anyone looking for reliable and professional service!
