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 installation of a new furnace. If you’re facing plumbing, HVAC, or carpentry 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.


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 carpentry work can get the job done for you.


We call it preventive maintenance for a reason: a well-maintained air conditioner system is less likely to have issues. During every maintenance visit, we’ll carefully inspect your existing systems and identify any emerging issues. By fixing small problems before they can become any worse, we’ll save you plenty of money on expensive replacement or repairs in the future.
