HVAC & Utilities Cost Guides

$25,000

$12,000 to $45,000 · 1-3 days

Install residential solar panels to generate electricity, reducing utility bills and increasing home value.

$3,500

$1,500 to $8,000 · 1-2 days

Install attic, wall, crawlspace, rim-joist, or basement insulation with target R-value, air-sealing checks, moisture control, ventilation protection, and rebate documentation.

$2,200

$800 to $5,000 · 1 day

Replace an aging water heater with an efficient model to reduce energy costs and ensure reliable hot water.

$7,500

$3,000 to $18,000 · 1-3 days

Mini-split (ductless) heat pumps deliver targeted heating and cooling without ductwork. Each indoor head connects via small line set through a 3-inch wall hole to the outdoor condenser. Cold-climate models (Mitsubishi hyper-heat, Daikin Aurora) maintain rated capacity to -5°F or lower. Federal IRA Section 25C credit covers 30% of cost up to $2,000/year for ENERGY STAR rated heat pumps. Highly efficient: 18-24+ SEER2 vs 13-16 for window units.

$10,000

$5,000 to $20,000 · 1-2 weeks

Install a new central HVAC, heat pump, furnace, or ductless system with load sizing, ductwork or line-set planning, electrical/gas scope, permits, startup testing, and warranty registration.

$8,000

$3,000 to $20,000 · 1-3 days

Spray foam insulation provides both insulation and air sealing in one application, making it the most effective solution for energy efficiency. Closed-cell foam achieves R-6 to R-7 per inch of thickness.

$8,000

$4,000 to $15,000 · 1-2 weeks

Whole House Repipe is a home improvement project in the Systems category.

$6,000

$2,000 to $18,000 · 1-3 days

Upgrading insulation is one of the most cost-effective energy improvements. Attic insulation alone can cut heating and cooling costs by 15-25%. Many utilities offer rebates that improve ROI further.

$15,000

$5,000 to $35,000 · 1-3 days

Standby generators automatically provide backup power during outages. In areas prone to severe weather, they add significant peace of mind and resale value. Natural gas units require no fuel storage.

$12,000

$5,000 to $28,000 · 1-3 days

HVAC replacement improves comfort, air quality, and energy efficiency. Modern heat pumps offer both heating and cooling at higher efficiency than separate systems, with significant operating cost savings.

$4,000

$1,500 to $9,000 · 1-2 days

An electrical panel upgrade is essential for older homes with 60-100A service that cannot support modern appliances and EV chargers. This project requires a licensed electrician and utility coordination.

$16,000

$9,000 to $35,000 · 1-3 days

Home battery installation provides backup power during outages and stores excess solar production for use at night. The federal 30% Residential Clean Energy Credit applies through 2032 for batteries 3kWh+. Most installs pair with solar; standalone batteries qualify as long as they exceed 3kWh capacity. Tesla Powerwall, Enphase IQ, and LG Chem dominate the residential market.

$700

$300 to $2,000 · 2-4 hours

Solar attic fans exhaust hot air from attics during summer, reducing the load on air conditioning systems. Solar-powered models operate at zero cost during peak cooling hours and require no wiring.

$10,000

$4,000 to $25,000 · 3-7 days

Homes with galvanized steel or polybutylene pipes require repiping to prevent failures, leaks, and water quality issues. PEX tubing is now the standard replacement, offering flexibility and freeze resistance.

$6,000

$2,000 to $15,000 · 1-3 days

Leaky or undersized ductwork wastes 20-30% of HVAC energy. Replacing deteriorated ducts with properly sealed and insulated metal runs significantly improves comfort and efficiency throughout the home.

$1,800

$800 to $4,500 · 2-4 hours

Water heater replacement is often required every 10-15 years. Heat pump water heaters use 60-70% less energy than standard electric tanks and qualify for federal tax credits.

$2,000

$700 to $5,000 · 4-8 hours

Whole house fans rapidly exhaust hot air through attic vents during cool evenings, dramatically reducing air conditioning runtime. In mild climates, they can reduce AC costs by 50-90%.

$1,500

$800 to $3,000 · 4-8 hours

Radon mitigation systems reduce indoor radon levels through sub-slab depressurization. The EPA recommends mitigation when radon levels exceed 4 pCi/L. Many buyers now require a radon test during home inspection.

$5,000

$1,000 to $20,000 · 1-3 days

Smart home systems increase convenience, security, and energy efficiency. Starting with a smart thermostat and security cameras provides the best value, with lighting and lock automation close behind.

$3,000

$1,200 to $7,000 · 1-2 days

Central vacuum systems offer more powerful suction than portable units while venting exhausted air completely outside the living space. They add a quiet, convenient cleaning solution to any home.
