City Park
The 330-acre park, established in 1880, is the neighborhood's defining amenity and its cooling influence, with evening breezes off the lakes and deep shade.

HVAC Services We Run Through City Park
City Park's late-1890s and early-1900s Denver Squares and bungalows are being popped up and renovated faster than anywhere in the city. A house that doubled in volume needs a new system design, and heat pumps are the retrofit path turning up most often on these blocks.
Heat Pump InstallationA bungalow or Denver Square that has been renovated or popped up takes a heat pump sized for the house as it stands now, not as it was built. One system heats and cools, and the sizing accounts for Denver's altitude and winter temperatures as well as the added floor.View details →Furnace RepairA pre-war bungalow furnace is often heating a house that has grown around it. The visit works from the burner outward — ignition, heat exchanger, venting — and then looks at the ductwork, since the original runs were never meant to serve a second story.View details →Ductless Mini-Split InstallationA wall head suits both: the bungalow that never had ductwork and the pop-top that added a second story. The new floor gets its own control without opening the original walls, and the ground floor keeps the system it already has.View details →Air Conditioning InstallationAdding cooling to a City Park bungalow means working with ductwork added decades after the house was built. The airflow gets measured before anything is sized, so the new floor and the old floor both get air.View details →Duct RepairHomes that grew a second story carry crushed flex runs, disconnected joints and undersized runs from two different eras of work. The runs get reconnected and supported properly, so the added floor stops stealing air from the rooms below.View details →

How We Run HVAC Work in City Park
The pop-top bungalow next to the zoo is the pattern here. These are the three decisions we make most.
Sizing for a house that doubled in volume
A 1910 brick bungalow with a pop-top is twice the house it was, and the original furnace and ducts cannot serve the new floor. Guessing from the old equipment guarantees a mismatch.
How we help: We run a fresh room-by-room load calculation for the renovated house, and we check whether the original system can still serve the ground floor properly.
The heat-pump retrofit path
Heat-pump retrofits are happening across this housing type, with a 2026 listing showing a new heat pump, furnace and AC in a 1904 Denver Square next door in City Park West.
How we help: We talk through heat pumps as a replacement path when a furnace and AC are both aging out, and we size for Denver's altitude and winter temperatures.
Basements, radon and the pre-war stock
Pre-war bungalows and Denver Squares typically have full basements, often finished, and radon mitigation is increasingly part of the conversation in this stock.
How we help: We remind homeowners to pair HVAC work with radon testing where a basement bedroom or finished basement is involved, and we check ductwork that runs through the basement.

Navigating City Park: Landmarks We Use
City Park is the neighborhood around the 330-acre park, and the park is the landmark. We use the zoo, the museum and the lakes as orientation points, and the bungalow blocks as the work.
Denver Zoo
The Denver Zoo anchors the park's north side and is our reference point for calls on the neighborhood's northern blocks.
Denver Museum of Nature and Science
The museum, opened in 1908, sits in the park and is the landmark we use to orient on the eastern blocks.
East High School
East High School at 1600 City Park Esplanade is a 1924 building and an individual Denver Historic Landmark, marking the neighborhood's southern edge.

City Park HVAC FAQ
HVAC in City Park: Common Questions
Lion Tech Home Services can help if your question is not answered here.
Call (720) 806-7634 →The original furnace and ducts were designed for a one-story bungalow, and the new floor has no ductwork of its own. It overheats while the ground floor stays comfortable, and a wall head on the new floor is usually the fix.
Heat-pump retrofits are happening across this housing type, including a 2026 example next door in City Park West, where a 1904 Denver Square got a new heat pump and furnace. Sizing is done for the house as it stands now, and for Denver's altitude and winter temperatures.
It is worth considering. Pre-war basements here are often finished, and radon mitigation is increasingly part of the conversation in this stock. Ask about it during a visit — the test and the HVAC work can be planned together.
The visit opens with the symptoms, then checks the ignition, blower, exchanger and venting in turn, with the findings explained before any work begins. In a pre-war bungalow, the flue's age and the basement's condition get a look as well.
