All reviews for McCarthy Services

McCarthy has since contacted and resolved issue very professionally.
Over the past twelve years McCarthy has installed two HVAC systems and provided numerous annual tune-ups.
Up until this last tune-up service I had been very pleased with the service provided by McCarthy, but this last encounter left me very disappointed.
When the technician arrived, he proceeded to the outdoor unit and visually inspected the unit, tightening a couple of screws to address vibration noise and then advised me not to have the refrigerant levels checked because that process would let refrigerants escape and cause problems.
He then proceeded to the inside unit and opened the door to the air filter. Without inspecting the filter, he proceeded to explain that the 4-inch filter system (installed by McCarthy) was problematic as it restricted airflow.
He then launched into a sales pitch for an electrostatic air filter. After listening for a while I told him I was not interested and asked him if he had finished with the interior unit and he responded that he was. He had not checked the unit temperature, airflow level or check for loose wires or thermostat accuracy or any other services listed on the attached coupon.
I then asked him about cleaning the outdoor unit as noted on your coupon (copy attached). He indicated that it would be a couple of hundred dollars more and not covered by the coupon offer, even though the service was listed. He then asked me to pay the $49 for the “service” which I refused as I felt no service was rendered and the visit was a pretense for a sales pitch for the electrostatic air filter.
As I have observed many tune-ups in the past, I find it hard to include this service encounter as a tune-up and will not be paying for something I did not receive.

Technician arrived on time. He was very professional and knowledgeable. He throughly explain the functionality of my HVAC and needed repairs. Mr. Berkeley ensued that my system was I. Top running order when he finished the service. Thank to Mr. Belle and MCCarthy for a job well done!

The service tech Shak, was knowledgable, professional, thorough, and kindky answered all of my questions. He shared important owner maintenence tips to keep my HVAC system clean and running smooth between service visits.

Service man replaced old water heater. He was on time did a great job within the estimated time he gave me. The price was also very reasonable.

Erik Hernandez is a great technician with outstanding customer skills. He was very proactive and resolved my heat system in record time. *****Five stars for Erik!
Erik, keep up your great work!

I had a fantastic experience with McCarthy beginning when they installed my new HVAC system in March. Today, they came out for a routine check-up and as always, the technician was prompt, professional, and knowledgeable about the system. Highly recommend!

Great communication and service from initial contact to install. All of the McCarthy team were professional and helpful. I'm really glad I worked with them and got a new HVAC system during the coldest week of the year!

Had the fan replaced in my furnace. Great job by tech Erik Hernandez. Erik was professional and courteous. He answered all my questions. Erik did an outstanding job

Arrived when promised. Talented and efficient technicians. Completed the installation of a heat pump in a timely fashion. The representative making the proposal was top notch and he delivered all that was promised. I highly recommend this company.

The technician was knowledgeable, courteous and professional. He provided a tune-up to my furnace and provided a thorough assessment. I appreciate the work that was done and the informative assessment on issues. The thorough knowledge of issues found provided me with the ability to make an informed decision about how to address issues found without any sales pressure. I respect a company that operates in this manner and will use them in the future.

Found them online with great reviews. Had an inspection, literally the same day with a quoted price. I forgot the guy that came here for the inspection and quoted price but he was very knowledgeable and was willing to work with me. The two technicians, Kenny Pham and Walter Grady came over literally the next day and installed it within a few hours. They have a 10 year warranty or something like that. I had called three other places before them and settled with them because their price was very competitive and they was willing to work with me. My old AC unit was over 20 years old and was running on old Freon, but this new AC unit run on the new type of Freon and wow, it cools the house fast and it’s so energy efficient. This new AC unit allows me to connect through Nest and control it online and has a lot of features and it cools the house so much faster! They have great pricing, guaranteed and the two technicians are very professional and did a great job explaining everything. I recommended them to my neighbors and friends! Call and ask, they are willing to work with you!

I've had nothing but great experiences with McCarthy Services. One of their technicians, Erik H, just finished a diagnostic job on my HVAC system that required some ingenuity and flexibility. It was a complicated job but he was patient and worked on it until he identified the issue and solved the problem. I will continue to utilize McCarthy Services for any issues that arise in the future!

Had a fabulous experience with technician Sopheak! He was knowledgeable, thorough and kind. I could see he went above and beyond for the service. Highly recommend Sopheak!

Technicians were on time; took care in protecting floors and my home when bringing in or taking out equipment. Received complete HVAC system; explained both heating and air-conditioning systems. Systems appear to be running well and looks nice and neat in place. Technicians were very professional; very much about the business at hand. Finished on time. Pleasant experience.

The technicians who did my HVAC installation were absolutely outstanding! They explained what would take place with the removal or my 18 year old ancient system, then explained what would be involved with installing the new system. Cleanup inside and outside was excellent. They now have a “customer to life!”

Weblist heat in 12 degrees temperature. The company that we typically use because they installed our systems (ARS) said their earliest availability was about 12 hours later so I called McCarthy Services. The technician was prompt, polite, professional, and he fixed the issue in no time. Thanks guys!

I had them come repair a tankless water heater which was installed 8 years ago. Took a lot of troubleshooting but Freddy fixed it. Definitely ask for him if you have a complicated repair, he is very knowledgeable and knows how to figure out an issue.

McCarthy provided our family support from Kenny and Lyndon from their team. We had a failed water heater in a home with a gas versus electric. They were both able to help us out in a rental property while keeping everything for the home owners neat. They were able to bring the water heater into our basement where the water heater was located and they laid down cloth mats to protect the carpet from stains. Professional from phone conversation, to installation, to review. Truly appreciate both of their help to get our household hot water again during the winter season.

The technicians were very knowledgeable and kept to appointment times. Installations were tested and explained well and the main office managed the process very well. Thank you McCarthy! We will recommend you to our friends.

Was very satisfied with McCarthy Services, for Lowe's approved installation of my new water heater. Francisco B and Lendon were prompt, professional, courteous and patient. Highly recommend McCarthy Services, their customer service and plumbing crew. Steve D., Alexandria, VA

Showed up exactly on time. Installation of furnace and air conditioner. Reviewed the work to be completed with me before start of installation and again after work was finished. Highly friendly and professional. Worked with McCarthy years ago and came back over 20 years later. Will continue to use them. You will be satisfied with their work. Feel confident with their service.
