HVAC System Installation
Equipment, plenum, flue and controls as one job
The equipment is only as good as what it inherits
A new condenser bolted onto an old, undersized plenum will run harder and cool less than the rating on its own nameplate promises, because the ductwork it inherits was never sized for it. Our own attic photos from finished jobs show what a complete install actually looks like: several air handlers with new sheet-metal plenums built to match the equipment, flue connectors run correctly on the gas side, and condensate lines routed with a secondary drain pan underneath rather than tucked in wherever there was room. One customer's review describes wanting the old system out entirely and everything updated including the ducts, and that is the job we plan for from the first walk-through rather than discovering halfway through the install.
What gets checked before the new equipment goes in
Static pressure and duct condition get looked at before a single piece of equipment is ordered, because a high-efficiency unit paired with a restrictive duct system will underperform and run louder than it should. Thermostat wiring is verified rather than reused blind, especially on anything with multi-stage or variable-speed controls. A secondary drain pan and float switch go in wherever the attic run allows for it, so a clogged condensate line trips a safety switch instead of a ceiling.
Financing and a guaranteed price match are both available for a full system installation, the same two things painted on our trucks.
ONE JOB, NOT THREE TRADES
Why matching the equipment to the duct system is the actual install
A full installation is really three trades happening in the same attic on the same day: sheet metal, gas and drain, and low-voltage controls. Skip the sheet metal side and a brand new condenser spends its whole life fighting a plenum built for the unit it replaced, which shows up later as short cycling and rooms that never quite reach the set temperature. Skip the drain and flue work and the failure shows up somewhere worse, a nuisance shutdown at best or water damage at worst. We treat all three as one scope of work, priced and scheduled together, because splitting them apart is exactly how a install ends up needing a callback within the first year.
A full install often changes the shape of the rest of the house's comfort too. If the new equipment is going in with zone dampers and more than one thermostat, see multi-zone systems and thermostats for how that gets planned alongside the equipment itself. If the ductwork is the part that needs the most work and the equipment is staying, our ductwork replacement and modification page covers that on its own. Either way, call day or night, or send the details through our contact page and we will walk the attic before quoting anything.
