Top Tech Mechanical Services was absolutely outstanding from start to finish. Professional, responsive, honest, and incredibly knowledgeable. Our technician, Dan, went above and beyond to make sure everything was handled perfectly. He took the time to explain the issue, answered all of our questions, and made us feel completely confident in the work being done. It’s hard to find companies these days that truly care about customer service and quality work, but Top Tech Mechanical Services exceeded expectations. Dan’s professionalism, attention to detail, and friendly attitude made the entire experience stress-free. Highly recommend this company and especially Dan if you want the job done right!

I had an outstanding experience with Top Tech Mechanical Services, thanks to their technician, Bobby Black. He came out to perform a thorough coil cleaning and my annual HVAC tune-up, and he was simply fantastic. Bobby was communicative from start to finish, letting me know exactly when he’d arrive and explaining each step of the process. The pricing was very reasonable, and I felt I was in the hands of a true professional. I also loved their tracking app, which allowed me to see exactly where Bobby was en route, adding to the convenience and peace of mind. If you’re looking for HVAC services done right, with both reliability and transparency, I highly recommend Top Tech.

My technician, Dan, was incredibly helpful and courteous! He did an excellent job with both tuning up my furnace and reasonably explaining my situation. He was even nice to my dog 🙂. Service was great and affordable, I would definitely recommend trying this place out!

What commercial HVAC services do you provide?

We handle commercial HVAC services for businesses, including AC and heating repairs, new system installation, maintenance, RTU work, and other HVAC needs.

Call if the system is not cooling or heating properly, the airflow is weak, the unit is making unusual sounds, or you notice leaks. It is better to check the problem before it causes a bigger breakdown.

Most commercial HVAC systems should be checked at least twice a year. Systems that run for long hours or have heavy daily use may need more frequent service.

We first check the building and its heating and cooling needs. The job may include installing the equipment, connecting ductwork and electrical lines, setting up controls, and testing the system.

It depends on the age and condition of the system. If the unit needs repairs often or the repair costs keep adding up, replacing it may be a better option than continuing to fix it.
