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.

You can rely on us for installations as well as maintenance packages suited to keep your system running dependably all winter long. Leave the repairs, replacements and seasonal checkups to the pros at CM Expert.

Fixing Faulty Furnace Ignition

One of the most common furnace problems that can develop is a faulty ignition system. If your gas furnace is having issues starting up or staying lit, the likely culprit may be a defective ignition component. Our certified technicians have extensive experience with troubleshooting and repairing furnace igniters skillfully. 

We will thoroughly inspect the ignition assembly to determine the specific cause, whether it’s a worn-out igniter, faulty gas valve or damaged thermostat wire. Using quality replacement parts, we ensure the ignition system is back to working properly. You can count on our expertise to get your furnace heating again by resolving any ignition issues effectively and safely.

Replacing Clogged Furnace Filters

It is crucial to replace your furnace filters regularly not only for efficiency but protection of the gas furnace components as well. Clogged filters obstruct airflow and can lead to premature part failure if left neglected over time. Our team understands the importance of fresh filters for proper functioning. We perform an inspection of the air filter as part of any furnace service and replace it if due. 

Using high-grade filters suitable for your unit’s needs, we ensure maximum airflow and filtration. This keeps contaminants from building up in the system while preserving its lifespan. Leave the periodic filter replacements to us so your furnace continues operating dependably with optimal gas efficiency and performance.

Limit Switch Repair

Among the components that ensure the safety of your furnace is the limit switch. This important device shuts the unit down when temperatures get too high for safe operation. Unfortunately, limit switches can sometimes malfunction, preventing the furnace from operating correctly. Our trained technicians are fully capable of diagnosing limit switch issues professionally and performing repair or replacement effectively. 

We carefully test the limit switch and circuit to isolate troubles. You can leave any repair needs with us, safe in the knowledge that we will carefully handle limit switch repairs to alleviate concerns and return your furnace to a fully functional condition.

Diagnose the Rumble

An odd rumbling or shaking noise coming from the furnace area can be cause for concern. It’s important not to ignore such sounds as they could indicate an underlying mechanical issue developing. Our expert HVAC technicians have extensive experience diagnosing the root cause of strange noises to catch potential problems early. We will thoroughly inspect components like the blower motor, heat exchanger and fans to isolate the source of the rumble. 

Using our expertise and properly calibrated tools, we can determine if repair or replacement is required to eliminate the noise. Our prompt diagnosis and high-quality repairs will ensure your furnace’s quiet operation with no cause for lingering worries.

Calibrate Your Thermostat

Over time, a thermostat can drift from its accurate temperature readings due to regular use and minor component wear. This means your furnace may not be activating at precisely the right levels. Our trained professionals thoroughly check thermostat calibration during regular tune-ups as a standard part of quality preventative maintenance.

 We use industry-approved tools and methods to properly recalibrate thermostats to factory specifications. This ensures your home heating and cooling system responds dependably according to current temperature settings. You can depend on us to perform any needed thermostat calibration, safe in the knowledge that your furnace will continue operating efficiently and economically.

Clogged Drain Solutions

No furnace should be left vulnerable to condensation issues caused by clogged drain lines. Over time, debris can accumulate in drains and prevent proper drainage of collected moisture. Our experienced technicians are fully capable of inspecting drain lines for blockages and implementing effective solutions. We access drains through the furnace or air conditioner cabinets to carefully clean out any obstructions. 

For severely clogged or corroded drains, expert drain replacement may be necessary. You can rely on our team to thoroughly inspect drains and take proper measures to ensure adequate moisture removal and circulation. Our drain solutions keep your system functioning at optimum efficiency year-round.
