Sanderson Gulch
The gulch runs through the hilly ground on the west side. Split-levels and tri-levels cluster near it, and its lots get a drainage check before basement work.

HVAC in Mar Lee for 1950s Brick Ranches
HVAC in Mar Lee is the story of the 1955 brick ranch that has never had real cooling. Builders filled these southwest Denver blocks mostly in the 1950s with modest brick ranches for the post-war boom — many with no central AC originally, or a swamp-cooler legacy. Lion Tech Home Services adds first-time cooling to these low, single-storey homes and replaces the original-era forced-air furnaces, now typically on a second or third system.

Mar Lee is a 1950s brick-ranch neighborhood, built mostly in the late 1940s through the 1950s, where many homes have never had real central cooling. First-time AC leads the list, furnace work covers systems now on their second or third replacement, and ductless covers the split-levels and tri-levels near Sanderson Gulch and the finished basements that stay cold while the main floor bakes.

How We Run HVAC Calls in Mar Lee
A small ranch with a finished basement needs a different plan than a two-storey house. Here is how we handle the three situations that come up most in Mar Lee.
First-time AC on a 1950s ranch
Many Mar Lee ranches never had central cooling. Adding it means sizing for a small, low footprint — oversizing short-cycles, leaves humidity behind and wears the compressor out early.
How we help: We run a load calculation for the house as it stands, check the ducts for the added airflow, and size the system to the real load rather than to the old furnace's nameplate.
The cold basement, hot main floor
Finished basements are common here, and the same single-zone system that leaves the basement cold in January leaves the main floor baking in July. One thermostat cannot serve two different floors.
How we help: We zone the basement separately or add a ductless head downstairs, so the lower level stops fighting the main floor for the same air.
Split-levels near Sanderson Gulch
The split-levels and tri-levels on the hilly ground near the gulch have upper and lower levels that never balance on one system, and gulch-adjacent lots need a drainage and moisture check before mechanicals sit low.
How we help: We check grading and basement moisture on gulch-adjacent lots first, then plan zoning or ductless for the levels that the original system never served well.

FAQs About HVAC in Mar Lee
Lion Tech Home Services can help if your question is not answered here.
Call (720) 806-7634 →Air conditioning installation for ranches that never had central cooling, furnace repair and installation, ductless mini-splits for split-levels and finished basements, and tune-ups for aging systems. Reach Lion Tech Home Services at (720) 806-7634 with the house type and the symptom in hand.
Any time of day or night. A furnace that quits in a 1950s brick ranch on a freezing January night or an AC that quits in a July heat wave. Lion Tech Home Services is staffed 24 hours a day in Mar Lee to take the call: (720) 806-7634.
In a Mar Lee ranch, watch for a main floor that bakes while the finished basement stays cold, no cooling at all on the hottest afternoons, a furnace short cycling, new noises, or bills climbing without a rate change. Call and describe the symptom and the age of the system.
Yes. The work here is mostly on modest brick ranches from the late 1940s and 1950s, plus split-levels and tri-levels on the hilly ground near Sanderson Gulch, many with finished basements. The plan is built around a small single-storey footprint and a furnace that has usually been replaced once or twice already.
No. A 1950s brick ranch is one of the best candidates for a first central AC: the house is single-storey, the furnace is usually due for replacement anyway, and the cooling can be added when the furnace is replaced. The sizing matters more than the age, because an oversized system on a small footprint short-cycles and never dehumidifies.
