The best! We had our furnace go out on Sunday, and Monday our new furnace and air conditioner was operational by 3 pm. I will recommend nardco to all my friends.

We have a heat pump and the air handler is in the attic = tough access.This year David and Andy worked most diligently to diagnose, and then replace many parts. It demanded a lot of patience and perseverance, and the Nardco men came though. We also have an annual service agreement with Nardco at a reasonable rate. When we call for help, the lady at the desk, Jocelyn, is very polite and reliably sets up appointments, and they show up at our home, when they say they are coming. We are presently all electric, but will explore moving to natural gas. We plan to call Nardco and request their expertise before we have a gas line put in. Thank you Narco!


Techs arrived within the time frame we gave them. Had the required part on the truck! Restored AC in less than 1 hr and checked the furnace for us. Showed the husband how to clean the AC unit and advised him on correct installation of programmable thermostat. Repair invoice reasonable. No pressure for additional services. Professional craftsmen.

Nardco clearly values investing in long-term relationships with their customers. Jim came out to service my old boiler/baseboard heating system (which most other companies won't service those anymore) - and he was extremely helpful and informative. We missed something the first time he was here, so he came out right away to finish resolving the issue. Very happy with Jim's work and dealing with Nardco. Thank you guys!
