HVAC Services We Run Through Cory-Merrill
Cory-Merrill is Les Tremblay country: solid-masonry brick ranches on 6,000-plus-square-foot lots, built for GI Bill financing in the 1940s and 1950s — and now the epicenter of Denver's scrape-and-build wave. Keep the ranch and replace the system, or scrape it and start over: that decision tree is the job.
Furnace InstallationReplacing a furnace in a Tremblay ranch means matching the new unit to solid-masonry walls and a full basement. Sizing starts room by room, accounting for the brick mass, and the unit gets put through a combustion check once it is set.View details →Air Conditioning InstallationCooling a Cory-Merrill ranch means working with ductwork added after the house was built. Measuring the airflow comes first, then the unit gets sized to the house and the lot, and the condenser goes where a generous lot leaves real choice about placement.View details →Heat Pump InstallationAt replacement time, a Tremblay ranch can take one heat pump covering heating and cooling. Sizing accounts for the masonry walls and the generous lot, and the heat pump gets proven across both modes before sign-off.View details →Duct SealingRuns added over decades in a Tremblay ranch leak at the joints, and sealing them often recovers capacity the house was already paying for. The seal gets confirmed with a pressure test, so the recovered capacity is measured rather than assumed.View details →Furnace RepairUnder a brick ranch, the furnace sits in a full basement, and the check runs burner, heat exchanger and flue in that order. Solid masonry hides a failing furnace well — the house holds heat long after the system starts struggling — so the visit looks at performance, not just whether the unit runs.View details →

How We Run HVAC Work in Cory-Merrill
Scraped or saved: the decision tree is the job here. These are the three conversations we have most.
The Tremblay ranch, scraped or saved
Cory-Merrill is the epicenter of Denver's scrape-and-build wave. Smaller 1930s-and-later homes are being scraped and replaced with large new homes and duplexes, and the HVAC decision follows the building decision.
How we help: We walk through the tree with you: keep the 1952 brick ranch and replace its furnace and AC, or scrape it and design a new system for the new house. The two paths share nothing but the lot.
What solid masonry does to the load
A Tremblay ranch is solid masonry, red or blonde brick with flagstone, and that mass changes how the house heats and cools compared with a frame house of the same size.
How we help: We size with a load calculation that accounts for the masonry, rather than applying a rule of thumb built for frame construction.
Generous lots, bigger houses, new loads
Lots here run 6,000-plus square feet, and the new homes going up on them are far larger than the ranches they replace. A new house on the same lot needs a completely different system.
How we help: We design for the new house, its glazing and its finished basement, with zoning built in from the start.

Cory-Merrill HVAC FAQ
HVAC in Cory-Merrill: Common Questions
Lion Tech Home Services can help if your question is not answered here.
Call (720) 806-7634 →That is a building decision first, and the HVAC follows it. Keep the ranch and the furnace and AC get replaced for the house as it stands. Scrape it and a new system gets designed for the new house. Both paths get walked through before the decision is made.
Brick mass absorbs and releases heat differently than frame construction, so a rule of thumb built for frame houses will mis-size a Tremblay ranch. Sizing starts room by room and accounts for the masonry, so the equipment matches the house instead of the estimate.
It can. A larger new home next door changes shade and wind on the shared lot line. If the system started struggling after nearby construction, the load and the duct balance are worth rechecking.
A repair visit starts by listening to the symptoms, then moves through ignition, blower, exchanger and venting, with findings explained before any work begins. In a Tremblay ranch, the basement's condition and the duct joints get a look too, since both age faster than the furnace.
