    Aeroseal Tech specializing in Aeroseal Technology and other ways to improve Air Quality, Air Volume and Velocity for residential and commercial buildings. We take on jobs ranging from simple to complicated and perform all work with the utmost attention to detail and customer service. This way we are able to achieve the best results for our customers which we guarantee for 10 years! Aeroseal Duct Sealing is a patented breakthrough technology that tackles leaks from the inside out. Aeroseal software allows the technician to accurately measure the duct leakage in residential homes and commercial buildings. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is closed. The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, whose IAQ scientists tested it. The research was funded by US Environmental protection agency, US dept. of Energy, Electric Power Research Institute and California Institute of Energy and Environment. The University of California was granted initial patents in 1996 and 1999, and Aeroseal holds an exclusive license to the technology.

FAQ: Common questions about air conditioning repair services in Mississauga

Are air conditioning repair pros in Mississauga insured and licensed?

In Mississauga, AC repair pros should hold a valid HVAC licence and carry both liability insurance and workers' compensation coverage. This is especially important for any work involving refrigerants, which are regulated under federal law. Before committing to a pro, ask for proof of both, and don't skip this step just because the repair seems minor.

Do air conditioning repair pros in Mississauga need a permit?

For most repair work in Mississauga, a permit isn't required. However, if the repair involves replacing a major component like a compressor, or any work that touches refrigerant lines or electrical systems, some municipalities may require one. Your pro should know the local rules and flag this upfront if it applies to your job.

How do I know if my air conditioner needs a repair or full replacement?

A good rule of thumb is to weigh the cost of the repair against the age of your unit. If your system is more than 10 to 15 years old and the repair costs more than half the price of a new unit, replacement is often the better investment.

Recurring breakdowns, rising energy bills, and uneven cooling are all signs that your system may be nearing the end of its life. If you're unsure, post your job on HomeStars to get quotes from air conditioning pros in Mississauga who can assess your system and help you make the call. You can also check out our guide to central air conditioner costs if you ultimately need a full replacement.

Can an air conditioning repair pro in Mississauga also handle my heating needs?

In most cases, yes. Air conditioning repair pros in Mississauga are often HVAC contractors who are just as comfortable working on your heating system as your cooling one. If you need someone to handle both, HVAC contractors in Mississauga on HomeStars are a good place to start, as many pros offer full heating and cooling services under one roof.

You can also take a look at our guide to heating and cooling costs to get a sense of what a combined project might run you.

Do air conditioning repair pros in Mississauga handle cleanup after the job?

For most repair calls in Mississauga, there isn't much to clean up, but a good pro should leave your space the way they found it. If a major component is being replaced, confirm upfront whether old parts and packaging are included in the removal or if there's an additional disposal fee.
