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.

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.

How much does AC installation in Richmond Hill Cost?

Determining the cost of an air conditioner installation can vary depending on many factors. The type of system, size, make, additional components and scope of work all influence projected 

We provide upfront quotes tailored to each project after a thorough site evaluation. In general, homeowners can expect that central air conditioning installation tends to be more expensive than a ductless or window unit. 

Our experienced team considers all particulars to deliver HVAC solutions following industry standards while avoiding unnecessary charges. Reach out to us for a complimentary consultation and customized proposal for your specific cooling needs. We aim to offer transparent budget guidance and installation options for any budget.


While a homeowner can attempt an air conditioning installation on their own, we do not recommend it for most situations in Richmond Hill. 


Proper AC system sizing, installation, and maintenance require specialized skills and certifications to ensure safety, efficiency, and durability. A DIY installation risks issues like improper ductwork layout, incorrect refrigerant charging, or failure to follow building codes. 


Our experienced team is fully licensed and insured, and they understand the unique construction and climate factors in Richmond Hill homes. For reliable results that protect your investment and warranty, it’s best to trust the job to a qualified pro like CM Expert.

Installing air conditioning is worth the investment for Richmond Hill homeowners. While our summers may not be as scorching hot as other parts of Ontario, temperatures regularly reach the high 20s with humidity levels that make indoor conditions feel significantly warmer. 


This uncomfortable interior heat can negatively impact the quality of life, especially for individuals with health conditions affected by temperature. Beyond comfort though, AC provides measurable benefits including improved energy efficiency. A properly installed central air conditioning system can enhance your home’s value and lower year-round energy bills by dehumidifying the air and allowing optimal performance of your furnace.

The amount of time needed to complete an air conditioning installation can vary depending on the specific system requirements and work involved. However, most typical AC installations in Richmond Hill homes take between 4 to 8 hours. 


This includes tasks like installing the outdoor condensing unit, running refrigerant lines through the attic/crawlspace, mounting and insulating the air handler unit inside, and connecting ductwork. 


Our team aims to minimize disruption as much as possible by working efficiently. Additional time may be required for tasks like acquiring permits, sizing equipment, and starting/testing operations once the physical installation wraps up.

There are a few signs that indicate it may be time for a new air conditioning system if you live in Richmond Hill:


  • Your unit is 15+ years old. Most AC equipment reaches the end of its useful lifespan after 15-20 years of use.


  • It’s not keeping your home cool enough on hot days. If rooms are warmer than a few degrees of your thermostat setting, efficiency is declining.


  • Repair costs exceed 30-50% of a new unit’s price each year. Continual repairs may signal it’s time for a replacement.


  • It often fails to start or has unusual noises/vibrations. These could indicate developing mechanical problems.


  • Ductwork is poorly insulated or leaking significantly. This saps efficiency and cooling capacity.
