Typical Price to Buy and Install a Guardian Air REME Unit

Standalone REME units sold for retrofit or DIY range from $450-$1,500 depending on the model and whether it’s OEM or a retail aftermarket version.

Most homeowners pay $600-$1,500 for a REME model plus installation, landing the average installed price near $1,200.

Assumptions: single‑family, 2-3 ton HVAC, accessible plenum, standard electrical circuit.

Parts of the Quote: Materials, Labor, Equipment, Permits, Delivery

Typical contractor estimates break down into parts: the REME unit, mounting hardware, electrician or HVAC labor, any new controls or transformers, disposal, and occasional permit fees.

Expect materials and labor to account for roughly 70–90% of the installed price; the unit cost is the single largest line item.

How Unit Size, Duct Type, and HVAC Capacity Change the Final Quote

Three strong variables change pricing: HVAC tonnage/airflow, duct accessibility, and model selection (basic vs commercial REME PRO).

• HVAC size: 1.5–2.5 ton systems usually fall at the low end; 3–5 ton systems can increase labor by 10–30%.
• Duct condition: tight access or rusted plenums can add $200-$800 for sheet‑metal work or custom brackets.
• Model: residential REME $450-$1,200 vs commercial/whole‑building modules $1,200-$2,500.

If the HVAC requires a new transformer or control wiring, add $125-$350 to the quote; complex plenums add $200-$800.

Practical Ways To Reduce Guardian Air REME Price Without Sacrificing Performance

Cost reductions typically come from scope control: buy the correct model, perform minimal prep work yourself, and schedule installation during off‑season slow periods.

• Buy the unit retail ($450-$850) and hire an HVAC tech only for electrical hookup ($150-$350).
• Bundle with planned HVAC service or filter replacement to reduce contractor mobilization fees.
• Avoid unnecessary upgrades like new thermostats or zoning during the REME install unless required.

Doing basic prep (clearing attic access, turning off breakers, having filters available) can cut labor time by 30–50%, reducing labor costs by tens to hundreds of dollars.

Regional Price Differences and How Location Affects Total Cost

Prices vary by market: urban and high‑cost states run 10–30% above national averages; rural markets and parts of the Midwest tend to be 5–15% lower.

Always request local quotes because labor and permit fees are the single biggest source of regional variation.

Add‑Ons, Replacement Parts, and Ongoing Maintenance Fees

Ongoing costs include replacement lamps or cartridges, periodic cleaning, and potential replacement fans or controllers over time.

Budget $40-$120 per year for maintenance and expect a lamp or emitter replacement every 1–3 years depending on hours of operation.
