It's the same crew and the same written rules for a capacitor on a Tuesday as for a full system changeout.

HVAC Repair
Not sure which part of the system quit? Start here. One visit tests the cooling side, the heating side, the controls and the airflow, then you get a named fault and a price.
- • Short cycling or tripping breakers
- • Strange noises from either unit
- • Water around the indoor equipment
AC Repair
The fan runs, the air coming out isn't cold, and the house keeps climbing past the setting. These are the summer calls, dead capacitors, iced coils, clogged drains and condensers that hum but won't start.
- • Warm air from the vents
- • Ice on the copper lines
- • Condenser humming but not spinning
AC Installation
Adding central air for the first time, cooling a finished attic or replacing window units with something permanent. We work out the size from the rooms themselves.
- • First central air in an older house
- • Ductless heads for a hard to reach room
- • Cooling for a new addition
Heating Repair
Start here if the house is cold and you don't know if you have a furnace, a heat pump or both. We work out what heats the house and what stopped it.
- • Gas, oil or electric heat
- • Pilot or ignitor problems
- • Rooms that never warm up
Furnace Repair
A gas furnace that clicks, lights for a moment and goes quiet. Most of these are flame sensing, ignition or draft faults, and we check the safety side on the same visit.
- • Ignitor glows but no flame
- • Burner lights then cuts out
- • Error code blinking on the board
Furnace Installation
A new furnace for a gut renovation, a house switching fuels or a unit too far gone to repair. We plan the venting and the gas line before anything is ordered.
- • Standard or high-efficiency options
- • New venting where the old flue will not do
- • Furnace for a finished basement
Heat Pump Repair
Electric bill doubled in January, or the outdoor unit is a block of ice. Heat pumps fail in their own ways, and most of them trace back to defrost, charge or a thermostat letting backup heat run.
- • Aux heat light on all the time
- • Outdoor fan stopped in winter
- • Blowing lukewarm air
Heat Pump Installation
Swapping electric baseboard or an aging AC and furnace pair for one heat pump that does both jobs, with the backup set to stay a backup.
- • Ducted heat pump systems
- • Ductless mini split heat pumps
- • Dual fuel with an existing furnace
HVAC Replacement
When the repair quote is most of the price of a new system, it's time to see both numbers on one page. We size the equipment from the house and check the ducts before ordering.
- • Matched furnace and AC sets
- • Heat pump changeouts
- • Old unit hauled away
HVAC Maintenance
A spring cooling check and a fall heating check, with readings written down each time so a slow problem shows up before it becomes a breakdown.
- • Spring AC tune-up
- • Fall furnace safety check
- • Maintenance plans for two visits a year
Thermostats
Smart thermostats that lose power, programs that never stuck, and heat pump controls set so the backup strips run all winter. Wired, configured and shown to you.
- • C wire runs
- • Heat pump and dual fuel setup
- • Programs that never held
Ductwork
The equipment is fine and the back bedroom still isn't. Leaky joints, crushed flex runs and missing returns waste the air before it reaches you.
- • Disconnected attic runs
- • Missing or tiny return grilles
- • Sealing ducts in a crawl space
Indoor Air Quality
A house that smells musty, feels sticky at 72, or coats the furniture in dust. We measure humidity and airflow, then match the fix to what the numbers show.
- • Whole-house dehumidifiers
- • Filter cabinets matched to the blower
- • Finding the source of a musty smell
Commercial HVAC
Rooftop units, split systems and apartment buildings kept running without shutting the business. Short notice, after-hours and weekend visits are booked ahead and quoted per job.
- • Rooftop unit repair
- • Planned maintenance for landlords
- • Tenant comfort complaints
