37 cost guides
An equipment price is only one part of an energy upgrade. The installation may also involve distribution, electrical supply, controls, drainage, or changes to the building. Start with a repair or replacement guide, then follow the related guides for the supporting work.
Separate homeowner filter care from professional coil, blower-wheel, drain, and cabinet cleaning. Compare mini-split cleaning quotes by the heads included and the condition the service can verify.
Compare garage electrical costs, a dated installed-price benchmark, trenching, interior wiring, and a worksheet for checking complete electrician quotes.
Compare electrical panel replacement with a service-capacity upgrade. Check equipment, utility coordination, permits, and the work included in each quote.
An EV charger quote should identify the charging equipment, planned charging rate, and route from the electrical panel to the parking location.
Budget San Diego’s published single-dwelling EV charging-system inspection fee and identify electrical work that can add separate charges.
Use the service quote to separate diagnosis, the correctly rated capacitor, and safe installation. This guide shows what a defensible quote should identify and how a parts price differs from installed work.
A condenser-fan motor quote should prove the motor match and include capacitor, electrical testing, fan setup, and system verification. Use this proposal checklist to compare OEM and universal options.
Compare an evaporator-coil proposal by model match, refrigerant circuit work, access, drain changes, and warranty labor. A parts-only warranty rarely equals a no-cost replacement.
A low refrigerant diagnosis should become a leak-test and repair proposal, not an unexplained top-off. Use this scope checklist to compare testing, recovery, repair, evacuation, recharge, and verification.
Compare attic insulation costs with air sealing, old-material removal, coverage, and preparation included. Check what each contractor leaves completed.
Compare attic ventilation proposals by soffit and ridge paths, air sealing, baffles, moisture sources, and fan pressure effects. A powered fan is not automatically an upgrade.
Use a written boiler service checklist to compare combustion, venting, controls, hydronic or steam checks, and the report you receive. An inspection fee should buy evidence, not a generic tune-up label.
Compare boiler replacement bids by heat load, AFUE, venting, combustion air, hydronic distribution, controls, and startup documentation. Equipment price alone hides the largest scope changes.
Compare ERV and HRV proposals by climate, moisture transfer, airflow, duct arrangement, controls, filters, and commissioning. The best quote explains the ventilation design instead of selling a box.
Review the Eastern Massachusetts Eversource heat-pump delivery classification published for April–July 2026 and its limits.
Estimate 90 kWh using historical Eastern Massachusetts R1 supply and delivery charges, with space-heating tariff eligibility kept separate.
Compare furnace blower motor proposals by PSC or ECM type, programmed controls, airflow setup, and warranty coverage. A part-only listing cannot be compared with a tested installed repair.
A furnace igniter quote should separate the ignition diagnosis from the exact replacement part and the combustion safety checks. Use this guide to compare a covered part with the labor that remains.
Compare cold-climate heat-pump bids by design load, low-temperature capacity, backup strategy, and duct or electrical scope. A tonnage guess is not a sizing method.
Compare heat pump water heater equipment and installation costs. Check the model, available space, connection work, and dated incentive assumptions.
Separate a blocked condensate drain from a failed pump, pan, or float switch before approving work. This comparison shows what should be tested and which follow-on water-protection items belong in the quote.
A duct-replacement quote should show the new layout, insulation, access assumptions, and balancing plan. Use this scope worksheet to compare complete duct bids rather than linear feet alone.
Compare duct-sealing proposals by measured leakage, accessible joints, aerosol process limits, insulation, and retesting. The useful number is verified improvement, not a generic promise of savings.
Compare HVAC maintenance plans by included inspections, visit timing, repair discounts, exclusions, and cancellation terms. Count the services you need instead of buying a vague promise of priority.
Compare HVAC replacement costs as a complete system: equipment selection, installation, supporting work, and operating assumptions behind the proposal.
A zoning retrofit is a controls and airflow project. Compare bids by thermostats, dampers, bypass or pressure control, equipment staging, wiring, and commissioning.
Compare equal heat output using dated Eastern Massachusetts R1HP electricity and Massachusetts propane inputs with explicit efficiency assumptions.
A mini-split quote should show the rooms served, the equipment selected, and the physical route of the installation.
Compare 45 kWh of hypothetical dehumidifier use at PG&E E-ELEC summer bundled rates, with timing and fixed-charge limits.
Steam and hot-water radiator replacements have different valves, vents, piping, and balancing requirements. Compare bids by system type and measured fit rather than radiator size alone.
Compare rooftop solar cost evidence, system size, installation scope, and purchase terms. Check the price period and incentive assumptions before budgeting.
Compare whole-house dehumidifier bids by capacity, duct arrangement, drain or pump, controls, electrical load, and commissioning. Drainage and airflow are part of the installed scope.
Compare whole-house humidifier bids by bypass or fan-powered design, water and drain connections, controls, duct access, and replacement-pad service. Product cost is only one line.
Calculate a hypothetical 600-kWh baseboard load using the historical Eastern Massachusetts R3 heating tariff, rather than a heat-pump rate.
Compare tankless water heater replacement with a storage-heater conversion. Check equipment, connection changes, and the installation work behind the total.
A water-heater replacement price should describe the model and the work needed to install it at the existing location.
Estimate a window air-conditioner session from Con Edison’s published residential TOU delivery rate and measured kWh.
Ask for the proposed equipment and design, the work included to make it operate, and a separate explanation of any savings estimate. Use your own tariff and usage when comparing running costs.
