Harvard Gulch Park
The green anchor, with golf, trails, a recreation center and an outdoor pool. The DeBoer district pocket sits across from it.
HVAC in Rosedale starts with an address check. This south Denver neighborhood west of the University of Denver — Evans Avenue north to Yale Avenue south, Broadway west to Downing Street east — is mostly 1920s–1940s bungalows, brick cottages, Tudors and ranches, with a median year built of 1941. But the oldest homes across from Harvard Gulch Park sit in the small S.R. DeBoer Historic District, a pocket rather than the whole neighborhood. Lion Tech Home Services checks the district first, then plans the work.

Just practical help.Rosedale is a 1920s-40s bungalow neighborhood with a median build year of 1941, and a historic-district pocket inside a non-district neighborhood: the S.R. DeBoer Historic District covers only the oldest blocks by Harvard Gulch. Furnace and AC work leads the list for the bungalow stock, ductless covers the infill duplexes and additions, and boiler work covers the oldest homes.
A historic-district pocket inside a non-district neighborhood changes the order of work. Here is how we handle the three situations that come up most in Rosedale.
The S.R. DeBoer Historic District is a pocket across from Harvard Gulch Park. Two houses on the same street can sit on different sides of the line, and exterior work inside the district needs landmark review.
How we help: We check the district boundary for the address before recommending exterior work, so a condenser or penetration is planned around the review rather than discovered by it.
Harvard Gulch is a drainage corridor, and gulch-adjacent blocks warrant a drainage and moisture check before finishing a basement or siting mechanicals low.
How we help: We check grading, drainage and sump needs on gulch-adjacent lots first, then place basement equipment above the moisture line the lot suggests.
The oldest Rosedale homes carry boiler legacy, and the 1920s–40s stock had central AC added later rather than built in. Each era left its own duct quirks.
How we help: We test the boiler and the radiation it serves, or the retrofitted duct system as it stands, before recommending a repair or a replacement.

Call (720) 806-7634 →Furnace repair and maintenance, AC installation, ductless mini-splits for infill duplexes and additions, and boiler repair for the oldest homes. Reach Lion Tech Home Services at (720) 806-7634 with the house type and the symptom in hand.
Yes, day or night. A furnace that quits in a Rosedale bungalow in a January cold snap or an AC that gives out on a July afternoon. The number to call in Rosedale is (720) 806-7634. Lion Tech Home Services is open all hours, every day.
In a Rosedale bungalow, watch for a furnace short cycling, rooms that never match each other, a boiler leaking near its base in the oldest homes, or a basement that stays damp near Harvard Gulch. Gulch-adjacent blocks warrant a drainage and moisture check before a basement is finished or mechanicals are sited low.
Yes. Most of the calls here come from classic Denver bungalows, brick cottages and Tudor-style homes from the 1920s to the 1940s, with a median build year of 1941, plus modern duplexes, townhomes and contemporary infill. The bungalow stock is the core of the calls.
Only the oldest blocks by Harvard Gulch sit in the S.R. DeBoer Historic District. It is a pocket, not the whole neighborhood, so the address is checked first: inside the district, exterior work needs landmark review; outside it, standard permits apply. That address check is the first step before any exterior equipment is planned.
