Derby homes are older than Adams County homes
Census figures count 2,611 homes in Derby, including 2,523 occupied homes. The median home was built in 1958 and has 5.4 rooms. Adams County has 191,765 homes, a 1990 median build year, and 5.8 median rooms. Derby calls for a room-by-room look at the house instead of an assumption based on newer county housing.
Homes built before 1960 account for 56.1% of Derby housing. That is far above Adams County at 13.5% and Colorado at 16.3%. Another 15.8% of Derby homes were built from 1960 to 1979. Older homes are more likely to lack ducts or have small ducts, so duct condition must shape the system choice.
Derby has a much smaller share of recent homes. Only 0.9% were built in 2010 or later, compared with 14.9% in Adams County and 14% statewide. A newer home and an older home can have the same floor area but need different equipment sizes. We measure the home before selecting capacity.
Homeownership is 66.8% in Derby, close to Colorado at 66.3% and below Adams County at 68.9%. The town has 79.6% detached houses, compared with 62.6% in the county. Detached homes offer many possible ducted and dual-fuel projects, but the existing duct system still determines if a central heat pump is the right path.
Derby compared with nearby towns
Derby has a 1958 median build year. That is older than Welby at 1974, Sherrelwood at 1966, and Twin Lakes at 1976. North Washington also has a 1958 median. Derby and North Washington need more attention to original ductwork and electrical equipment than their newer nearby towns.
The before 1960 share also sets Derby apart. Derby is at 56.1%, while Welby is at 19%, Sherrelwood is at 30.9%, and Twin Lakes is at 35.3%. North Washington is at 59.8%. Derby's older housing stock makes an in-home measurement important before choosing a ducted unit, a dual-fuel system, or ductless equipment.
Gas heat is the leading fuel in Derby at 75%. Welby is close at 76.4%, while Sherrelwood is at 68.4% and Twin Lakes is at 72.7%. North Washington has 54.1% gas heat and 45.9% electric heat. Derby's larger gas share means many homes begin with a furnace replacement decision rather than an electric-heat replacement.
Derby has 4.7% multi-unit buildings. That is below Welby at 21.5%, Sherrelwood at 24.2%, and Twin Lakes at 15.5%. North Washington is close to Derby at 4.9%. The lower multi-unit share in Derby puts more focus on individual detached-home systems, while ductless equipment remains a strong fit for condos and small multi-unit homes.
How Derby homes heat today
Utility gas heats 75% of Derby homes. Electricity heats 21.2%, and propane heats 3.2%. Adams County has 68.8% gas heat, 27.1% electric heat, and 2% propane heat. Fuel type affects rebate eligibility and whether a homeowner wants to keep an existing furnace for the coldest hours.
A heat pump moves heat instead of burning fuel, and it also cools the home. In a gas-heated Derby house, a ducted heat pump can replace a central system when the ducts are suitable. Dual fuel keeps the gas furnace for the coldest hours. That option aligns with the 75% share of homes that now use utility gas.
Electric heat serves 21.2% of Derby homes, compared with 25.2% across Colorado. For a home without ducts, ductless equipment provides heating and cooling without adding a central duct system. It also fits additions and condos. The best layout depends on the home, not just the fuel listed in housing data.
Mobile homes account for 14.9% of Derby housing. That is higher than Adams County at 5.8% and Colorado at 3.6%. We measure the home and check the electrical panel before installation. A home type does not determine capacity, panel requirements, or the number of indoor ductless units by itself.
Choosing among ducted, dual-fuel, and ductless systems
A ducted heat pump is a good match for a Derby house with ducts that can serve the new equipment. Derby has 79.6% detached houses, compared with 61.8% statewide. Many detached homes have central heating layouts, but Derby's 1958 median build year means duct size and condition need a direct check before we recommend this option.
Dual fuel is built for a home that already has a gas furnace. The heat pump provides heating and cooling, while the furnace remains available for the coldest hours. With 75% of Derby homes using utility gas, dual fuel is a practical system path for a large part of the local housing stock. It avoids treating every gas furnace replacement as the same project.
Ductless heat pumps suit homes without ducts, additions, and condos. Derby has 4.7% multi-unit buildings and 14.9% mobile homes. Those homes can need a different layout than a detached house with a working central duct system. Ductless indoor units are planned around rooms and the measured heat load.
For the ductless example, a 1,500-square-foot one-story home with electric heat and no ducts uses 3 indoor units in our estimate tool. The pricing approach uses 500 sq ft of floor area per ductless indoor unit. The estimate prices up to 5 indoor units before a custom quote is needed.
Sizing heat pumps for Derby cold and altitude
Our estimate tool sizes equipment to 1°F outdoors and 70°F indoors at 5,300 ft. Air-source heat pumps lose 18% of heat output at that elevation. At the design temperature, the equipment produces 2 units of heat for each unit of electricity. These conditions set the required capacity for a Derby home.
The example is a 2,000-square-foot, 2-story home with a gas furnace, built before 1960. Its design heat load is 3.4 tons, and the estimate uses a 40 A breaker. This example reflects Derby's largest construction group, because 56.1% of local homes were built before 1960.
A 2,000-square-foot, 2-story gas home built from 1960 to 1979 has a 3.2 tons design load in the estimate. The same home built from 1980 to 1999 has a 2.8 tons load. Homes built from 2000 to 2009 use 2.4 tons, while homes built in 2010 or later use 2.0 tons.
These examples show why floor area cannot select a heat pump on its own. Derby has 56.1% of homes built before 1960, 17.1% built from 1980 to 1999, and 10.1% built from 2000 to 2009. We measure the home, inspect ducts, and check the electrical panel before installation.
Example prices for older Derby homes
Our estimate tool prices the 2,000-square-foot, 2-story gas-heated example at $17,400 to $37,800 before rebates for a ducted heat pump. The after-rebate range is $9,900 to $30,300. The home has a 3.4 tons design load and represents the before 1960 group, which accounts for 56.1% of Derby homes.
For the same example home, dual fuel costs $14,000 to $30,600 before rebates and $6,500 to $23,100 after rebates. This system retains the gas furnace for the coldest hours. It is a direct option for a town where utility gas heats 75% of homes and older houses need an equipment plan matched to their ducts and furnace.
For the 1,500-square-foot, one-story electric-heated home with no ducts, the ductless example uses 3 indoor units. It costs $11,800 to $19,200 before rebates and $7,500 to $14,900 after rebates. This example addresses the 21.2% of Derby homes that use electricity for heat and the homes that do not have suitable ducts.
Most installations take one day. Projects with several ductless units can take 2 or 3 days. Brands we install include Mitsubishi, Bosch, Daikin, Carrier, and Trane. The online estimate takes about 2 minutes, and a winter gas bill makes it more accurate.
Derby rebates and the 80022 ZIP code
Our estimate tool shows several rebates that stack for qualifying Derby projects. The Xcel Energy rebate is $1,500 per ton of heating for Xcel Energy customers whose homes now heat with a gas furnace, gas boiler, or propane. It applies to each of the 3 system types. The State of Colorado Heat Pump Discount is $1,000 for every Colorado home.
Power Ahead Colorado adds $1,500 for homes in Adams County. For a 3-ton ducted heat pump in a gas-heated home, the total is $7,000. That total includes the Xcel Energy rebate ($4,500), the State of Colorado Heat Pump Discount ($1,000) and the Power Ahead Colorado rebate ($1,500). The Colorado state discount comes off the invoice, and we file every rebate for the homeowner.
A home now using electric heat has a different Xcel Energy rebate amount of $750 per ton of heating. For a 3-ton ducted heat pump, total rebates are $4,700. The total includes the Xcel Energy rebate ($2,200), the State of Colorado Heat Pump Discount ($1,000) and the Power Ahead Colorado rebate ($1,500). The gas-heated example has $7,000, so the fuel being replaced changes the available total.
