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.

We Fix all the Furnace Repair Issues

When your furnace is no longer functioning as it should and you need prompt furnace repair in Mississauga on, you’ll appreciate our wide range of repair services. Our knowledgeable technicians can handle problems of all different levels. But no matter what specific concern your furnace has developed, Our team has the expertise, tools and OEM parts necessary to resolve the problem. When professionals with years of hands-on experience are resolving your furnace repairs, you can rest assured the issue will be fully addressed for reliable heat all season long.

Fixing Faulty Furnace Ignition

One of the most important systems controlling your furnace’s ability to provide steady heating is the ignition component. If this piece becomes faulty and stops sparking the burners to life, your furnace will fail to initiate the process of warm air circulation. Some common signs of a faulty ignition include intermittent heating function, strange smells coming from the unit, or pilot lights that keep going out. 

The professional furnace technicians at CM Expert are highly skilled at diagnosing and correcting ignition issues to restore reliable heating performance. With our background servicing all ignition types from gas valves to electrodes, you can trust them to quickly fix ignition problems. A new component or simple adjustment is often all that’s required to solve ignition errors and return your furnace to smoothly providing comfortable, efficient heating once again.

Replacing Clogged Furnace Filters

A regularly replaced furnace air filter is one of the simplest yet most important maintenance tasks to keep your heating system operating at its best all season long. Over time, furnace filters absorb indoor allergens, pollen and other particles as air passes through. Once clogged, they block airflow and restrict your furnace from properly circulating warm air through vents. This leads to inefficient function and potential damage. 

We thoroughly inspect filters as part of all maintenance checks, promptly replacing any that are dirty or worn. By addressing filter clogs before they affect performance, your furnace maximizes its energy usage and provides optimal warmth. Maintaining clean filters is a quick affordability that prevents much larger repair bills down the road.

Limit Switch Repair

When excess heat builds up inside your furnace, a limit switch operates to shut it down and prevent potential danger. However, these safety components can malfunction over time—especially in older units. Limit switch issues may cause inconsistent furnace operation or refusal to ignite and run at all.

As one of the top professionals in furnace repairs throughout Mississauga, Our technicians have replaced countless worn or defective limit switches through the years. They have both the know-how and OEM parts on hand to conduct this repair rapidly and correctly. Our goal is always to resolve any furnace problems like limit switch errors thoroughly and efficiently.

Diagnose the Rumble

Beyond a simple failure to turn on, your furnace may indicate an issue through strange noises like a new rumble emanating from the appliance. These aberrant sounds could signify problems from loose or worn bearings to issues within the heat exchanger itself. 

Let the experts investigate any unfamiliar furnace noises to determine the root cause. With state-of-the-art diagnostic tools and years of finely tuned assessment skills, they can pinpoint what’s causing the rumble or other abnormal noises. No mystery is too difficult for them to solve! You’ll gain peace of mind knowing their expert diagnosis protects your furnace from further damage.

Calibrate Your Thermostat

Whether digital or analog, a faulty thermostat leads to inefficient furnace operation and irregular indoor climate adjustments. Over time, indoor/outdoor temperature sensors may drift off calibration which throws off your unit’s ability to maintain consistent, personalized heating comfort. 

CM Expert’s technicians thoroughly examine thermostats as part of annual maintenance tune-ups. They expertly calibrate any sensors through established methods using top-grade tools and precise techniques to re-align with accurate room and climate readings. Residents once again enjoy precise temperature regulation throughout their homes thanks to properly calibrated controls.

Clogged Drain Solutions

No homeowner wants to deal with flooding from a blocked condensate drain during chilly weather. This plumbing issue is a common one affecting furnaces that can be prevented with regular maintenance. As part of their seasonal check-ups and drain cleaning services, CM Expert’s technicians inspect condensate pumps and flue drains for blockages from mineral buildup or debris accumulation. 

We expertly employ hydrojetting machines, chemical treatment and inspection cameras as needed to clear clogs before overflow occurs. You’re assured effective non-invasive drainage repairs without lengthy system disconnection. Our prompt attention delivers peace of mind against unexpected messes and significantly larger restoration costs.

How much does it cost to fix a furnace in Mississauga?

The cost to repair a furnace in Mississauga can vary depending on the nature of the problem, the furnace components involved, and the specific services needed. Several factors influence furnace repair pricing:

    • Appliance age and manufacturer – Newer systems with common parts are generally more affordable to service while specialized components may raise costs.
    • Type of repair – Basic issues like filter changes have lower labour vs repairs replacing major internal parts.
  • Required components – Original manufacturer parts help ensure durability but can impact expenses.
