Repairs, Service, or Installations for Your Home. Call Us!


Owning a home or business means there will be up-keep and repairs. Some will be small like a drywall repair or sink clog, but some may be large like a wiring upgrade, or installation of a new furnace. If you’re facing electrical, plumbing, HVAC, carpentry, or home performance service, repair, installation or concerns in any of these areas, we’ve got you covered. Custom Mechanical is your one-stop company for large and small repairs, service and installations.

24 hours


If your furnace, heat pump or air conditioning isn’t keeping your home comfortable, our technicians will respond promptly to your call and are available 24/7 for emergency service. We’ll arrive with a fully stocked vehicle so most repairs are completed on the first visit.


Sink stoppage, toilet clog, water heater replacement, leaky faucets, remodels and everything else plumbing related, is part of our comprehensive package of home services. We have the expertise to take care of all your home plumbing needs.


Your electrical system is a matter of safety and we take that very seriously. Troubleshooting issues, installing upgrades, new systems, lights or ceiling fans, cable or telephone wiring; we’ll provide an up-front estimate and flat-rate pricing.


Home improvements often involve carpentry work. Perhaps you’d like to rebuild your deck, add an attic drop-down stair, replace a few windows, widen a doorway, repair some drywall or fix a few cabinets. Our decades of experience can get the job done for you.

I've used Custom Mechanical twice for AC system issues troubleshooting -- once in June 2017 and again in May 2018. In both instances I was impressed by the technicians' professionalism, efficiency, and technical knowledge. Each technician was able to clearly articulate the issues and their findings to me in understandable terms. I will continue to call upon Custom Mechanical for my HVAC system service provider needs and unequivocally highly recommend this firm.

This company is very thorough. When the tech came to inspect our crawl space encapsulation he detected a gas leak under the house that we were not aware of, tagged it and advised me immediately to call our gas company. I really appreciated that.

My hot water heater was spraying water and I called Custom Mechanical. I was told the earliest someone could get here would be 5:00 pm. A tech called at 3:30 to say he’d be on his way. He was efficient, very friendly and very professional.

He explains everything he will be doing then makes sure there are no problems with the finished job. His customer service skills are outstanding.
