What you actually pay for on an HRV/ERV install
Outer-ring Lakeville homes — older core near Holyoke and downtown, boom plats south and west — need clarity on labor scope before core type. This page explains what is inside a Furnace Direct flat install quote. We do not link equipment product pages; we do not sell DIY boxes.
Climate math that steers HRV vs ERV here
South-metro winters still punish houses that push continuous outdoor air without recovery. Heating degree days remain high enough that an HRV pays its keep on sealed 90s stock with fogged glass. On post-code plats that already sit under ~25% indoor RH in January, an ERV avoids turning ventilation into a humidifier problem you then fight with pans and complaints.
Rule of thumb we use on Lakeville quotes: moisture complaint → HRV, arid tight build → ERV, measured RH breaks ties.
Scope table — labor & materials categories
| Included in typical flat install | What it covers | Notes for Lakeville jobs |
|---|---|---|
| Core unit set & secure mount | Hang/platform the HRV or ERV cabinet in mechanical room, basement, or conditioned garage | Newer plats often have cleaner bays; older core homes may need platform carpentry |
| Outdoor air & exhaust hoods | Wall or roof terminations, insect screens, freeze-aware placement | Wind across open southern plats matters for hood side choice |
| Duct transitions & insulated runs | Connect to outdoor air path; short insulated runs as designed | Long attic runs on ranches add labor — called out before you sign |
| Condensate management | Drain routing, trap, pump if gravity fails | Finished lower levels need tidy concealed routes |
| Controls & continuous rate setup | Wiring, homeowner setpoint briefing | We set a winter starting rate matched to core type |
| Commissioning balance | Measure supply vs exhaust; adjust dampers | Non-negotiable — unbalanced units ice or under-ventilate |
| Haul-away of failed exchanger | When replacing | Photo the old data plate before we remove it |
What is usually NOT in the base number
- Major electrical panel upgrades (rare)
- Opening finished ceilings for surprise duct paths without prior approval
- Whole-home duct redesign unrelated to the ventilator
- Permits beyond standard mechanical where a city requires extra reviews — we flag these
Outer-ring growth vs older Lakeville core
Boom plats south and west often arrive with tighter envelopes and mechanical rooms ready for a cabinet — pricing leans clean if outdoor hoods are straightforward. Older core near Holyoke may need longer insulated runs or creative condensate routing after finished basements. Neither pattern changes the climate math: sealed + muggy → HRV; sealed + arid → ERV.
How core choice changes scope slightly
HRV and ERV cabinets install with the same labor categories above. The difference is which core we hang and how we brief you on winter RH targets — not a mystery surcharge line. Replacement jobs that reuse outdoor hoods can price leaner than first-time penetrations on a finished ranch.
