Signs It's Time to Replace Your Central Air Conditioner
Your System Is Getting Old
Most central air conditioners last 15–20 years. If yours is approaching or past that mark, repairs become more frequent and less cost-effective.
Repairs Keep Adding Up
If you've called for repairs more than once in the last two summers, the cost of "just fixing it again" may already be close to the cost of a new, more reliable system.
Your Home Has Never Had Central Air
Older Mississauga homes originally built without central air can be retrofitted, either with ducted central AC or a ductless system depending on your layout.
Your Energy Bills Keep Climbing
Older units lose efficiency over time. A modern system, correctly sized, can noticeably reduce your summer electricity costs.
Uneven Cooling Throughout the House
If some rooms never cool properly no matter how long the system runs, it may be an installation or capacity issue that a proper reinstall can solve.
What a New Central AC Installation Typically Costs in Mississauga
Every home is different, so pricing depends on the size of your home, the efficiency rating you choose, and whether your existing ductwork can be reused. As a general guide for the Mississauga area:
- Standard-efficiency central AC: typically $3,000 – $5,500 installed
- High-efficiency (18+ SEER2) central AC: typically $5,000 – $8,500 installed
- Furnace + AC replaced together: often saves $800 – $1,500 in combined labour versus replacing separately
- Ductless mini-split systems: a good option for additions, finished basements, or homes without existing ductwork
Final pricing is always confirmed in writing after a free in-home assessment – no guesswork, no surprise charges on installation day.
Choosing the Right System and Size
Getting this right matters more than the brand name on the unit. An oversized system cools too quickly without removing humidity properly, leaving your home feeling clammy. An undersized system runs constantly and never quite keeps up on the hottest days.
Proper Load Calculation
We assess your home's square footage, insulation, window exposure, and existing ductwork — not just a rough BTU-per-square-foot estimate — to recommend the right tonnage for your home.
SEER2 Ratings Explained
Higher SEER2 ratings mean better energy efficiency and lower summer electricity bills, but also a higher upfront cost. We'll help you weigh the payback period against your budget.
Ductwork Considerations
If your existing ducts are undersized, leaky, or in poor condition, we'll flag it — a new AC connected to bad ductwork will never perform to its full potential.
Brand Options
We install Carrier, Lennox, Goodman, Trane, Bryant, and other major brands. We'll walk you through the real differences between them so you can choose based on your budget and needs, not marketing.

Central AC Installation FAQs
How long does a central AC installation take?
Most standalone central AC installations take one day. If ductwork modifications or a combined furnace/AC replacement are involved, it may take 1–2 days.
Can I install central air if my home has never had it?
In most cases, yes. It depends on whether there’s a feasible path for ductwork. If ducting isn’t practical, a ductless mini-split system is often a better fit.
What brands do you install?
We install all major brands, including Carrier, Lennox, Goodman, Trane, and Bryant, and can help you compare options based on your budget and home.
Do I need a permit for a new central air conditioner?
Yes, permits are typically required for HVAC installations in Ontario. We handle the permitting process as part of the installation.
Is a bigger AC unit always better?
No. An oversized unit actually performs worse. It cools the air quickly but doesn’t run long enough to properly remove humidity, leaving your home feeling damp.
Should I replace my furnace and AC at the same time?
If both systems are aging, replacing them together usually saves on labour costs and ensures the two systems are properly matched for efficiency.

Needed help getting our air conditioner working again, great service. Tamer knows his stuff, was thorough, clean and explained everything he was doing as he went along.
I've been having issues with poor airflow at a number of my vents in addition to some freezing in my furnace room in my home in Mississauga. I found Tamas Mechanical online. They have great reviews, and after speaking with Tamer and having him complete his diagnostic, I see why. Tamer was professional, patient, and fair throughout my engagement with him.Tamer quickly identified the issue and tweaked some settings to resolve it. I will be going back to Tamer for all my HVAC needs going forward!
Overall I had an excellent experience with Tamer installing a smart thermostat in my home. He was very polite, organized, knowledgeable and very easy to work with throughout the process. I have already booked him in to service the furnace for next season. I would highly recommend hiring him for any work needed.
The gentleman was very knowledgeable, experienced and extremely helpful. He was fast in repairing my gas leaking pipe. I plan to use him again in the future. His company deals with gas leaks, furnace maintenance, duct cleaning and air conditioning maintenance. I'm a very satisfied customer.
Tamer was excellent in diagnosing and fixing a complicated furnace issue we had. This was not my first time using Tamer and it won’t be my last. He is our go to guy for HVAC. Very professional, conscientious and good at what he does. Would highly recommend.
I hired Tamas Mechanical Inc., for furnace and duct cleaning. Tamer’s team, Mahdi and Blessing, did a great job. Mahdi was careful and efficient with his work. I also appreciated that they were respectful of us and cleaned up after the service. Tamer was very responsive when I was inquiring and booking. Had a smooth and easy experience with them. I highly recommend these guys and would hire them again in the future.
Tamer did the job perfectly, he came ontime and his dedication to do task properly was obvious. Highly recommended
Had a great experience with this company. I was having a BBQ at my new house in a couple of days and needed an HVAC company to install a new natural gas line for my BBQ. I put a request in Homwstars and got a call from Tamas very quickly and arranged for a technician to arrive the next day and provided a quote over the phone based on some photos and measurements. Tamer was the technician and took about half a day to install the new line which worked perfectly. One small issue was that my fireplace pilot went out during the installatio and I couldn't relight it. But Tamer came back to do a manual light at no extra charge. Very happy with the service, price and friendliness of staff.
Tamer was a helpful guy. Helped fix my problem within a couple of hours. Would recommend him for any hvac issues.
I was struck by how honest he was. Didn’t charge me for a small task months ago and quickly resolved an issue today. Good workmanship and great value. I’m happy to rely on Tamas for my HVAC needs.
Tamer is great and makes sure all your equipment is in running order. Way better deal than something like Reliance. Here is the Bryant AC unit that he installed for us.
Tamas Mechanical provided great service. Was able to get a quote over the phone with a few pictures and have them completed 2 days later. Amazing work!
We needed repair work done on our HVAC/furnace. He was quick to respond, and quick to get to the repair. The price was very reasonable for great and honest work. Tamer was exceptionally knowledgeable and will not give empty promises. He was detailed and transparent in showing and explaining what the problem is, what he would recommend, and also allowed me the option to choose which route I wanted to take to truly fix the problem. He does not give you the run-around and works as quickly as possible without compromising quality. We felt like we were truly taken cared of. On top of that, the repair was flawless! We highly recommend Tamas Mechanical, and will gladly use his service again (should we need future repairs/ installations).
Tamer was very responsive and took time to understand the air conditioning issues and set very realistic expectations based on facts. Scheduling a visit was quick and easy, he arrived on time and did what was needed quickly while also being patient and took time to answer all questions and explained the details in relation to possible replacement of our old A/C and Furnace without trying to oversell us on anything. We would definitely recommend Tamas to everyone if you want someone who is clearly hardworking, wants to earn an honest living and win customers over the right way! Thank you Tamer and really appreciate your time and effort, you will definitely be our go to person for any heating/cooling issues.
I received excellent advice from Tamer regarding what power/BTU furnace I should choose. Prior to calling Tamas Mechanical, I had called several other companies, where I was getting conflicting and not clear advice on what BTU size I should choose. However, Tamer was clear on what BTU size I should choose and fair in the pricing. I was able to get advice on a Monday morning and order the unit by Tuesday and fortunately they accommodated me and had it installed two days later! The furnace is currently working well and keeping us warm and I also have a new humidifier April air 500 series that was also recommended and seems to be making the air in our house better. I will now be getting my ducts cleaned by Thomas mechanical and look forward to this service from them. I highly recommend this company.
We had Tamas come out due to a leak. He was professionally, timely and super friendly again this time. We are very satisfied with the work he did.Tamas is a great guy. Very friendly and informative. He installed a tankless water heater for us which has been working great. Also gave us a great price compared to what we were being quoted by others. Will definetly use his services in the future.
Tamer was quick to come diagnose our furnace and very knowledgeable on what the problem was. He took the time to answer our questions and listened to our concerns. He stayed in contact and updated us about when the part was going to be available and it was a quick turn around. He was very accessible and efficient. We would definitely recommend and use tamer again!
Tamas Mechanical were a pleasure to deal with. They replied promptly to my request, showed up within 12 hours and diagnosed the problem. Although the repair was beyond their scope, they were honest and upfront and recommended another company. I would use in the future if the need arises and recommend to others.
Tamer Sayer was the technician who came to service my furnace. I should preface my furnace is 14 years old and two other companies failed to fix the issue. Tamer spent over two hours diagnosing the issue and fixing it. Three weeks later furnace is still running like new. Al very grateful 🙏
