A BIG thankyou to all of the folks at WeatherFix for their fabulous service and support. After making every effort to repair my 37 year old AC system, they installed a new Lennox AC system ... during one of the hottest periods of the summer. Their quoted price was excellent and all of the necessary work was done with expertise and efficiency. It was a pleasure to work with a company that still has honesty and integrity as their core values. I highly recommend WeatherFix to anyone needing to service or replace their AC system.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

Ottawa has thousands of older homes — heritage properties, century bungalows, and split-levels — built without central ductwork. Adding new ductwork costs $5,000–$12,000 and involves major structural work. A ductless mini split eliminates all of that.
WeatherFix is the right call if your Ottawa home has:
Call 613-720-4567 now — our Ottawa technicians will assess your home and recommend the exact right system.
Every WeatherFix technician holds 313D refrigeration certification, fully licensed and insured for Ottawa HVAC installations. We comply with all Ontario codes — no exceptions.
We know Ottawa’s housing stock inside out — from century homes in the Glebe and Centretown to newer builds in Orleans. We size every system based on Ottawa’s actual climate demands, not generic specs copied from a manual.
An incorrectly sized mini split short-cycles, fails to control humidity, and wears out years early. WeatherFix performs a proper load calculation on every single job — so your system performs exactly as designed from day one.
We install Mitsubishi, Fujitsu, and Daikin — engineered specifically for Canadian winters and proven to perform down to -30°C. We don’t offer units that underperform when Ottawa’s temperatures hit -25°C.
Ottawa homeowners replacing electric baseboards with a cold-climate mini split heat pump may qualify for up to $7,500 in rebates under the Home Renovation Savings Program. WeatherFix handles your eligibility check before installation — so you never leave money on the table. Learn more in our Ottawa HVAC heating guide.
Every ductless mini split installation Ottawa project at WeatherFix follows a precise process. No shortcuts. No guesswork. No surprises on your invoice.
We visit your Ottawa home, measure each room or zone, and perform a proper BTU load calculation. We recommend the right system size, brand, and configuration — single-zone or multi-zone — based on your actual needs and budget.
We match the right unit from Mitsubishi, Fujitsu, or Daikin to your home’s layout, Ottawa’s climate, and available rebate programs — not just whatever model is easiest to install.
Our 313D-certified technicians mount the indoor air handler, position the outdoor compressor, run refrigerant lines through a small exterior wall opening, and complete all electrical connections to Ontario code. One zone typically takes one day.
We charge the refrigerant, test both heating and cooling modes, verify airflow and temperature output, and confirm the thermostat is operating correctly before we leave your Ottawa home.
We walk you through filter care, seasonal operating tips, and every rebate program your installation qualifies for. The job isn’t closed until you’re 100% satisfied.

Ontario Rebates in 2026: Replacing electric baseboard heaters? You may qualify for up to $7,500 in combined rebates. Homes with existing gas heating may still qualify for $2,000+. WeatherFix confirms your eligibility before a single tool is picked up.
Every technician is certified in refrigeration, HVAC installation, and electrical systems — fully licensed to serve Ottawa homeowners safely and to Ontario code. We are fully insured and bonded.
We perform a Manual J load calculation on every central air conditioner installation in Ottawa. Incorrect sizing is the industry’s most expensive mistake — we eliminate it entirely.
Ottawa’s humid continental climate demands specific expertise. We understand the humidity loads, temperature swings, and ductwork challenges Ottawa homes present — whether it’s an older heritage property in Centretown, a semi-detached in Westboro, or a newer build in Orleans.
Improper installation voids manufacturer warranties. Our certified process keeps your warranty fully intact. We also handle rebate eligibility so you maximize available savings.

I recently had a heat pump installed by Mahmoud and his team and I couldn’t be more satisfied with the entire experience. From start to finish, the process was smooth, professional, and hassle-free. The team took the time to understand my home’s heating and cooling needs, explained the benefits of a heat pump, and recommended a unit that fit both my budget and requirements. There was no pressure, just honest and helpful advice. I highly recommend WeatherFix for anyone considering a heat pump installation.

Mahmoud and his team came to fix my furnace and AC and I had a great experience dealing with them. I did not have the same experience with other companies. Highly recommend them they are honest hard working people who will go out of their way to get the job done.
