Reliable and prompt. My go to HVAC team.since 1999!

Overcharged 2.50 Hours and counted it as overtime for 2 mechanics.
New heater was dented and scratched.

Andy has been great to work with. He's helped us at our home and business.

Calvert Mechanical has provided an outstanding service, reasonable prices, and professional solutions from small jobs to large jobs over my 25 year experience with the company.

They have HORRIBLE customer service. Communication barely exists as to the job status. Rarely return phone calls. Milk the labor hours on every job. Overpriced. Would not recommend AT ALL.

This company's mechanics supervisors and overall quality of workmanship is outstanding. Working with them was a great experience.

Calvert Mechanical Solutions far exceeded my expectation! They are HVAC geniuses! They are spending 12 hours just testing, balancing and honing the new systems. Calvert measured the CO (if any) and CO2 output of the heating systems, measured air pressure, calculated air flow based on room size and replaced ducts to ensure correct air flow.

During the installation, they found several things wrong with the duct work that was installed when the house was built. We had main ducts blocked, a coil installed in totally the wrong place, vents not sealed and ducts not level. We had over 2 cubic feet of holes in our system due to shoddy work; and this is how the system was installed. They fixed all the duct issues and did the job right! Instead of just patching the holes, they made new ducts; instead of reusing the old wiring, they ran all new wires. They even installed the new units so I could easily change the filters, which involved shifting the units. They even took the time to install new pads outside for the AC units and they removed all the extra dirt and rock (not just dumped it in the woods). My other quotes were just going to reuse the pads, and once I saw them, I knew they had reached their useful life.

Calvert also tested the units using complex tools that showed the exact performance of the system. They then tweaked the systems to maximize their efficiency. I was totally impressed! The most amazing part is that they did all this for no extra charge. They estimated I was losing about 20% to 50% efficiency due to the issues above.

Given the quality of the work, I highly recommend them. Please keep them in mind if you need any HVAC work done. I know other companies can put in new units and get them running. The science of the process though is how the units actually work to heat and cool your house. Calvert excels at customer service!

Salesmen are highly unprofessional, office personnel is rude and standoffish, absolutely could not wait to get me off the line. Older electrician made some very inappropriate remarks throughout the duration of the job, the other guy with him spent nearly all the day lounging around in his vehicle.

Charged 4.5 hours for a job that was done in 30 minutes. Crooks.

Had a service appointment today...all around great customer service. From Alexi the Dispatcher to Dan and his helper the Service guys to Connie in billing great customer service. Only time I've have repair work done and the office calls to say they can come an hour earlier.Amazing!!! Would def recommend and use again.

Calvert review
Leon the contract manager is great and he came out to inspect my system free to make sure if my HVAC would be in good shape to sign up a yearly maintenance plan. He found out my system needed a service first.
I was happy to work with him and would sign up a maintenance plan afterwards!!
But badly, it ended as one time deal without maintenance plan afterwards! Why?

Because the company’s billing is not honest.

First I was told by Leon and later signed a service contract through email which stated labor $165 / per hour (minimum one hour + driving time 30mns) + material fee

The repaired time was 1.5 hours , but technician would not give me an invoice bill with repair time after service done. Very weird, I thought! ( Because I have lived in Maryland 46years and always got an invoice to pay right after service done. )

3 days later, I received an invoice through email and was charged 3.5hours of labor with $165 per hour+ material fee
(not 1.5 hr of actual labor+ driving .5 hr)

I was shocked to call the billing department where & why there is extra 1.5 hours ?

I was then explained by the billing department that they always charge their client through technician’s truck parking time not their actual labor service time.
In other words, extra 1.5 hr was technician’s walking time + writing time of my repair note.

( Later they adjusted their mistake of overcharge me 30 mns since the tech did not work overtime. )

Still, one hour extra charge not related to actual Labor service time is very unusual .

In my opinion, Calvert should be honest to put on contract as their billing department states “they bill on the truck parking time through GPS, not the labor time. “ this can avoid the customer’s confusion.
Or just have technician give the invoice bill immediately after service done as most other company done.

Transparency is a key in business.
