If you are planning to replace an air conditioner, furnace, heat pump, or water heater in Metro Detroit, one of the first questions is usually cost. Randazzo Heating, Cooling & Electrical created this HVAC Pricing Guide to give Southeast Michigan homeowners a practical starting point before scheduling an in-home estimate. The guide compares Good, Better, and Best equipment options, starting installation prices, equipment features, and some of the conditions that can affect the final cost of a replacement.
Every home is different, so the final price of an HVAC or water heater installation can vary. Equipment capacity, efficiency, existing ductwork, gas piping, electrical requirements, venting, refrigerant lines, installation access, permits, and code requirements can all influence the total investment. The prices below are intended to make it easier to understand your options and determine which equipment level may fit your comfort goals and budget.
Air Conditioning and Cooling Installation Pricing in Metro Detroit
Randazzo cooling system installations represented in this guide start at approximately $6,500. Homeowners can choose between Lennox Merit and Elite air conditioners or step up to a Dave Lennox Signature Collection heat pump for variable-capacity heating and cooling.
The right system depends on more than its starting price. Home size, cooling load, existing furnace or air handler, ductwork, efficiency goals, humidity control, and long-term comfort preferences should all be considered.

Water Heater Installation Pricing in Metro Detroit
Water heater installations represented in this guide begin at approximately $2,000 for a traditional Bradford White natural-draft tank water heater. A Bradford White power-vent system starts at $3,000, while the Navien tankless option starts at $8,000.
These options represent three different approaches to producing hot water. A conventional natural-draft system may be appropriate when the existing home is already configured for that type of water heater. Power-vent equipment provides greater flexibility for some venting situations, while a tankless system eliminates the traditional storage tank and requires a different installation configuration.
Water Heater Installation Costs
- Good: Bradford White RG240T6N Natural Draft Water Heater
- Starting at $2,000
- Traditional tank-style gas water heater
- Natural-draft venting configuration
- A straightforward replacement option for homes already designed for conventional atmospheric venting
- Better: Bradford White RG1PV40S6N Power Vent Water Heater
- Starting at $3,000
- Traditional tank-style gas water heater
- Power-vent configuration
- Provides additional venting flexibility compared with a natural-draft water heater
- Best: Navien NPE-240A Tankless Water Heater
- Starting at $8,000
- Condensing tankless hot water system
- Wall-mounted design eliminates the traditional storage tank
- Premium option for homeowners interested in high-capacity tankless hot water
Before recommending a water heater, Randazzo can evaluate your household’s hot water demand, current equipment, available installation space, gas supply, venting, plumbing, electrical requirements, and other conditions. Learn more about water heater services in Metro Detroit.
What Can Affect Water Heater Installation Cost?
A direct replacement can be relatively simple when the new water heater uses the same configuration as the existing equipment. Converting to another type of system can require additional plumbing, gas, venting, or electrical work.
- Water heater type and capacity
- Natural-draft, power-vent, or tankless configuration
- Gas line sizing and gas piping modifications
- Water supply and plumbing changes
- Venting modifications or new vent installation
- Electrical requirements for power-vent or tankless equipment
- Expansion tank and pressure-control requirements
- Drain pans, drain lines, or leak-protection improvements
- Equipment location and accessibility
- Required safety or code upgrades
- Permits and inspections
Why Can the Final Installation Price Be Different?
Publishing starting prices gives homeowners a useful benchmark, but no online pricing guide can account for every mechanical condition in a home. Two homeowners can choose the same equipment and still require different installation work because of ductwork, venting, electrical service, gas piping, equipment access, or code requirements.
An in-home estimate allows Randazzo to inspect the existing system, determine the correct equipment size, identify required modifications, and explain the complete installation before work begins. That makes it easier to compare the total installed solution rather than focusing only on the price of the equipment itself.
Financing a New HVAC System or Water Heater
Heating, cooling, and water heater replacements are not always planned expenses. Randazzo offers HVAC financing options that can help qualified homeowners spread the cost of eligible equipment and installation over time.
Available plans, rates, promotional financing, rebates, approval requirements, and monthly payment amounts can change. Review current financing options with Randazzo to determine which programs are available when you purchase your system.
