Very reliable

Raul was very personable and professional. He called in advance to confirm and came back as promised the next day to fix our dryer after his initial diagnosis.

Price was the highest of all contractors I asked for a quote from. Not at all competitive with other companies for the same product and service. Definitely recommend getting multiple quotes from different contractors before selecting a company. Edit: to answer below, the reason for one star is because the job was not to repair something. It was to replace. All the other contractors were quoting for the same replacement. The actual price will not be lower than your quote will it? Price gouging is not a good business model

Our washing machine was rattling and making a lot of noice so we did a google search for repair service. We found out during this search that Certified Mechanical has the designation of Google Guarantee which means (Businesses with the 'Google guaranteed' badge are screened, and are guaranteed to get the job done right or your money back with a lifetime cap of $2,000. ) Anthony the owner of the establishment sent a repair technician and the charged us for $99 to see visit out place and diagnose the problem. The repair was going to be costly so we decided to purchase a new washer and dryer. We called Anthony to provide us with quotes of 3 brands and see which one was in stock and we decided to proceed with the brand that was available and in stock. (This was not our 1st choice but we had did not want to wait 2 weeks plus) We understand the supply chain issues and low inventory and wanted the delivery and install to be done within 3 days. The only thing that I would say is that Certified Mechanical had to outsource the installation of the machines to another trade but we are happy with Certified Mechanical that the trades assigned to install the machines did a good job. Thank you Google for screening the vendors as it sure helps in make a decision and thank you for the $2000 guarantee.

Ronnie's definitely a magician, in the best way possible. I work in the property management field and had an issue with a high end commercial dishwasher. Ronnie was on time, professional and informative. He was able to not only fix our machine but leave it functioning better than it was pre breakdown. Keep guys like this around, your sanity and your wallet will thank you.

Thank you for your excellent service as always. Ronnie is so knowledgeable and good to work with. Always a pleasure!

Absolutely happy with the service that was provided. It was professional, quick, and honest. Anthony was able to come and access the problem with my fridge and was able to fix it within 15 min. Whoever requires any kind of repair, Anthony and his company is the company you need to contact. Unfortunately I previously had hired another company and they simply scammed me and didn't fix anything. Disappointed that I didn't find Anthony sooner. I would give more than 5 stars if I could.

Types Of Air Conditioner Units We install in Ajax

Whether you need a basic mini split installation or a comprehensive central air conditioning unit setup, CM Experts can handle all types of indoor cooling system installations proficiently. Some of the most popular air conditioning unit options we provide include mini splits, central air conditioners, package units, PTAC units and variable refrigerant flow systems. Our professional team offers expert advice and assistance to help customers select the best-suited AC depending on budget and project space specifications.

Central Air Conditioner

A central air conditioner is a popular whole-home cooling solution that comprises of an outdoor compressor unit and an indoor air handler connected by a ductwork system. It conditions and circulates air evenly throughout multiple rooms utilizing a single thermostat control. 

CM Experts’ team of HVAC professionals has extensive experience installing premium central air conditioning brands all over Ajax. We ensure precise duct sizing, expert equipment placement and thorough system testing for maximum performance and energy efficiency.

Ductless Air Conditioner

For areas that are not suitable for ducted central systems, a ductless mini-split air conditioner makes for an excellent alternative. It includes an outdoor unit connecting to one or more indoor wall-mounted cassettes through a refrigerant line. Ductless AC offers flexible, zoned cooling without ductwork. 

CM Experts is highly experienced in installing Mitsubishi, LG and Fujitsu ductless systems. We ensure optimal equipment sizing and positioning for effective temperature regulation within minimum installation timelines.

How much does AC installation in Ajax Cost?

The total cost of air conditioning installation in Ajax can vary significantly depending on various factors such as the type of AC unit, size, number of indoor units, complexity of ductwork requirements if any, permits, location of installation and additional services needed. 

In general, homeowners can expect the cost for a mini split AC installation to be on the lower end comparatively, while central AC systems tend to be more based on the scale and scope of the project. Besides equipment and labor charges, external aspects like duct replacement or insulation work may also impact the overall budget. 

We provide free, no-obligation quotes tailored specifically to each project after thoroughly evaluating all the site-specific details. The final price is determined only after a comprehensive analysis of the job requirements.


While installing air conditioning may seem like a straightforward DIY project, there are several factors to consider that make it better to trust the job to qualified experts. 


Our temperate climate and building codes require specialized skills and certifications to size, install and charge residential AC systems safely and effectively. 


Doing the work yourself also voids manufacturer warranties if any issues arise down the line. Our licensed technicians have years of experience navigating the unique installation considerations around the Greater Toronto Area, like drainage and venting requirements.

The answer depends on your individual needs and lifestyle. While our climate is more moderate than other parts of the province, several weeks of warmer weather each summer make AC a worthwhile comfort upgrade for many. 


It allows enjoying your home freely without feeling too hot or bothering with fans. The value also extends beyond comfort – studies show students and professionals alike are more productive in temperature-controlled environments. Proper AC sizing and installation by our technicians help minimize energy costs too. 


With Ajax’s growing population and development, summers are trending warmer. Installing AC now means enjoying your cool home for many seasons to come as the climate changes. Whether you work from home, host guests often, or simply want to relax in comfort, air conditioning can be a smart home improvement for Ajax residents.

The time required for air conditioning installation in Ajax can vary depending on the specific system and project scope, but most typical residential installations with CM Expert take between 4-8 hours to complete.

A large portion of that time frame involves:


  • Properly sizing the unit to your home and climate needs
  • Installing the outdoor compressor unit
  • Running and insulating the connection lines through the attic/crawlspace
  • Mounting and setting up the indoor evaporator coil or furnace casing
  • Vacuuming and charging the system with refrigerant


Factors like additional ductwork, electrical work or scheduling around other trades can occasionally require more time but the vast majority of our AC jobs wrap within a half-day to a single day. You can feel confident booking time off work or making other arrangements knowing to expect a speedy yet thoroughly done installation from the experts at CM Expert.

There are a few signs that generally indicate it’s time for a new air conditioning system if you live in Ajax:


  • Your existing unit is 15+ years old. Most AC equipment reaches the end of its reliable lifespan within 15-20 years with regular use and maintenance.


  • It’s struggling to keep your home cool on even moderately warm days. Reduced efficiency means higher energy bills too.


  • You notice oil leaks or corrosion on exterior metal parts which can indicate internal wear.


  • Your unit frequently cycles on and off more than usual. This could point to broader mechanical issues.


  • Repair costs have approached half the replacement cost of a new unit within a few years.


We can perform a comprehensive inspection and determine if a replacement is needed. Catching issues early avoids expensive breakdowns or having to replace an aging system in the middle of summer.
