Indoor air quality is very important to us. Not having the right AC system in your house, or not replacing your air filters regularly, can cause many health problems.

Trident Mechanical Systems takes pride in giving you the best indoor air quality when replacing an old air conditioning system and dirty air filters.

Having old and deteriorated duct work in your house can cause your air conditioning system to not perform properly. This can restrict air flow causing hot and cold spots in the house. Energy loss is another determinate of poor duct work in a house leading to a high energy cost.

Let the professionals at Trident Mechanical Systems inspect the integrity and efficiency of the duct system in your house.

Honest, Responsive, Professional

I called Sean for a second opinion on a so called “mandatory” furnace replacement from another well known HVAC company. Sean was on time and professional. After doing an inspection on our furnace, Sean assured us that our current furnace was working just fine, there were no issues at all. The other company was trying to scam us. Sean saved us over $4,000 dollars! We highly recommend Sean and we will definitely be using him for ALL of our HVAC needs.

Absolute Best!

This group of men are the absolute best! Sean,Ryan,Tristan and Austin. I will be a life long customer. Great equipment installed. I had the works done at my residence and I'm 110% satisfied. New condenser, new coil, new furnace, new Honeywell thermostat, new duct work in attic with new flex hose. Im a man that speaks from the heart. These men are Leaders not Followers! Don't waste time calling others. Your going to get the very best in all areas when you call Trident. Price, service, top of the line equipment, most importantly men they do what they say they are going to do and follow through!

Quick Response

Quick response time, professional team. Plenty of communication (perhaps a bit overzealous on that front, but I’d rather hear from you then have silence). Will be using them again.

Great Service

Great service. Appreciated them taking time to explain the issue with my unit and helping me keep a lemon unit going until I can replace it.

Very Impressed

Very impressed with Trident Mechanical Systems. They were able to repair my hot water heater the same day I called for the appointment. They were knowledgeable, friendly, and honest. Trident is so much more reliable than the larger chain companies that tried to sell me an overpriced (and as it turns out, unnecessary) new water heater. Couldn't have asked for better service.

We moved to Concord a year ago and having been using Trident for our HVAC needs and they have been great. Just this week we had to replace our main unit. Their response to the need, pricing and installation was all exceptional. We would recommend Sean and his team to anyone.

Excellent Job

Shawn and his team did an excellent job with our hvac system. We came home late one night to find our house at 80+ degrees. We called Trident Mechanical and Shawn came out right away. He had us up and running in not time.

If you're looking for a great company that is going to treat you like family..... give Shawn a call.
