Our services
Every request fits one of three lanes. The lane decides the first visit we offer.
Repair
Call us when your furnace, air conditioner, heat pump, mini-split or thermostat has stopped working, works poorly or sounds wrong. We diagnose it, explain what we found and give you a written estimate. The repair starts once you approve it.
- No heat or no cooling
- Weak airflow from the vents
- Turns on and off often
- New rattling, buzzing or squealing
- Water around the indoor unit
- Ice on the refrigerant lines
Smell gas? Leave the home first
If you notice a gas smell, a carbon monoxide alarm, smoke, or a strong burning or electrical smell, leave the home and call your gas utility or emergency services from outside. Don't use this website or the request form for it. Northdial does not offer emergency response.
Installation and replacement
For a new or replacement gas furnace, central air conditioner, air-source heat pump, ductless mini-split or thermostat. It starts with an in-home assessment, then written options with an estimate. We size the new system for your home instead of copying the old unit.
- Replacing an older or failed system
- Adding central air
- Switching to a heat pump
- Ductless for a room or addition
- Floors and paths protected, old unit removed
- Startup check and walkthrough at the end
Maintenance
For systems that work now. Many homeowners book a fall heating check and a spring cooling check. Each visit follows a set list of inspect, clean and test steps and ends with written visit notes. If we find a problem, you get a separate written repair estimate to approve.
- Fall heating check
- Spring cooling check
- Inspect, clean and test steps
- Written visit notes
Thermostats
Thermostats sit across two lanes. If yours is blank, won't respond or the house never reaches the setting, that's a repair. If you want a new thermostat, or you're replacing it along with a new system, that's an installation.
- Blank screen: Repair
- Not reaching the setting: Repair
- Upgrade to a new thermostat: Installation
- New system and thermostat: Installation
