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.

We Fix all the Furnace Repair Issues

Whether you need service, maintenance or repairs, our experienced technicians at CM Expert have the skills and equipment to handle any furnace problem you may face. Our team has the expertise to thoroughly diagnose the root cause and get your furnace back providing safe, reliable warmth again quickly so you can rest assured even during extreme weather conditions.

Fixing Faulty Furnace Ignition

One common furnace problem encountered is a faulty ignition system that prevents the unit from starting up as it should during the call for heat. We are capable of quickly diagnosing ignition issues like failing igniters or flawed flame sensors that disrupt the combustion process. 

We have replacement parts in stock and the expertise to meticulously overhaul ignition components when repairs are needed. Dealing with ignition failure doesn’t have to disrupt your schedule or comfort, thanks to our fast same-day service and deep understanding of furnace functionality. Leave ignition issues to our highly skilled team so your furnace operation returns to peak performance.

Replacing Clogged Furnace Filters

It’s easy for furnace filters to become clogged with dirt, dust and other particles over time. When this happens, it restricts airflow through the heating system. Our technicians routinely check filter conditions whenever a service call is made. Dirty filters are cleaned or replaced since restricted airflow can lead to insufficient heating and increased utility costs. 

We recommend the proper filter type and replacement schedule to keep your furnace operating at maximum efficiency. Prevent future repair needs down the road by making regular filter checks and replacements part of your routine home maintenance plan.

Limit Switch Repair

Limit switches are an important safety component within furnaces that shut the system off when temperatures get too hot. However, limit switches may prematurely fail due to age or defects. This interrupts the heating cycle unexpectedly. Our technicians are fully capable of diagnosing limit switch problems through sensor testing. 

When repairs are needed, we can professionally replace defective limit switches. Proactively addressing limit switch concerns helps avoid potential overheating issues or component damage in your furnace. Leave your limit switch needs to our team of experts for swift repairs that allow your furnace to operate reliably through its full lifespan.

Diagnose the Rumble

Have you noticed an unusual rumbling, vibrating or other intermittent noise coming from your furnace? Our certified mechanicals are highly skilled at pinpointing the cause behind noisy furnace operations. It could be anything from worn bearings and motors to loose or disconnected components. 

We will diligently inspect and test your entire HVAC system to isolate the precise issue creating the rumble. Knowing why these sounds occur is the first step to getting your furnace fixed. Leave the diagnosis to our experienced team so any underlying problems can be properly addressed before they lead to bigger issues down the road.

Calibrate Your Thermostat

An improperly calibrated thermostat can disrupt your home’s heating comfort and efficiency. Our technicians will carefully check any digital or analog thermostat you have for accuracy in both measuring and regulating temperatures. We have the tools and expertise to calibrate it to manufacture specifications if it’s not performing as it should. 

Such minor adjustments keep your heating system delivering more precise temperature control, which can also save you money on heating bills in the long run. Let the professionals at CM Expert ensure your thermostat is calibrated for optimal comfort and convenience during each seasonal change.

Clogged Drain Solutions

Poorly draining condensation can be a sign of deeper issues or simply blocked drain lines. Our technicians will assess your furnace’s entire drainage system, including the drain pan and connecting pipe leading outdoors. Using specialized tools and methods, we can effectively clear even stubborn clogs that cause water to back up. 

After identifying the root cause, we ensure the issue is fully corrected to allow proper future flow. Drain clogs left unaddressed could lead to costly indoor flooding or structural damage over time. Protect your investment by putting your draining concerns in our reliable hands for prompt attention.
