HVAC in Montclair for TB Houses & Historic Homes
HVAC in Montclair has no single system — it has a catalog. Founded in the late 19th century as a suburb promoted by Baron Walter von Richthofen, annexed by Denver in 1902, Montclair is, in architect Tom Morris's words quoted in Wikipedia, a catalog of architectural styles from 1885 to the present. Lion Tech Home Services works across that whole catalog: boilers and radiant heat in Victorian and Queen Anne houses and the tuberculosis-era TB houses, forced-air conversions, and ductless where no ducts exist.

HVAC Services Available Across Montclair
Montclair runs from 1885 to the present: Victorian and Queen Anne houses, TB houses built for tuberculosis sufferers, bungalows, cottages, Tudor Revival and modern ranches on large lots. Boiler work leads the list for the oldest stock, ductless covers the houses that never had ducts, and furnace and AC work covers the conversions and the later ranches. The 1975 historic district covers only the central heart, not the whole neighborhood.
Boiler RepairBoiler repair for Montclair's Victorian, Queen Anne and TB houses: a boiler leaking near its base, a failed circulator, a bad relief valve or short cycling. Pressure, expansion tank charge and zone valves are checked first.View details →Boiler InstallationBoiler installation for a Montclair house whose old boiler has reached the end of its life, planned around radiators, sleeping porches and room layouts that were drawn for fresh air, not ductwork.View details →Ductless Mini-Split InstallationA ductless head for a TB house or an 1885-1940 home with no ducts, cooling the rooms that need it without gutting plaster or cutting a chase through a house built for open windows.View details →Furnace RepairFurnace repair for the Montclair homes converted from boiler heat to forced air, and for the later ranch stock: short cycling, no heat, cool air from the vents when heat is called for or ignition that will not hold.View details →Air Conditioning InstallationAC installation for a Montclair home starts by measuring the load on the house that accounts for the grand old trees and large lots, then a check of whether the address sits inside the 1975 historic district core before exterior equipment is placed.View details →

How We Run HVAC Calls in Montclair
No two Montclair houses take the same plan. Here is how we handle the three situations that come up most.
Heating and cooling a TB house
Tuberculosis-era houses were built for fresh air and sleeping porches. Their envelopes and room layouts fight modern ducted systems, and the wide mix of eras means no single Montclair system exists.
How we help: We start from the house's era and envelope: boiler and radiator care where it serves, ductless heads where ducts cannot go, and forced-air conversion only where the structure allows it without gutting the house.
Inside or outside the 1975 district
The Montclair Historic District covers the central heart only. A house two blocks outside it has no landmark review; a contributing property inside it needs design review for exterior changes.
How we help: We check the district boundary per address before recommending exterior work, so a condenser or penetration is planned around the review rather than discovered by it.
Grand old trees and summer load
Montclair has among the best mature canopy in the city, and shade materially cuts summer load on the historic core. It also drops debris on outdoor units.
How we help: We size cooling for the shaded reality of the lot, not a generic Denver number, and we plan condenser cleaning and airflow clearance around the tree cover.

Getting Around Montclair
Montclair is a leafy east Denver grid. We use Richthofen Castle and the Molkery as our historic markers, and the large lots and grand trees as the sign we are in the old core.
The Molkery
Built in 1888 and now the Montclair Civic Building. It anchors the old core where the 1975 historic district sits.
Montclair Historic District
Designated in 1975, the city's fifth landmark district. It covers the central heart only — we check the boundary per address.

FAQs About HVAC in Montclair
Lion Tech Home Services can help if your question is not answered here.
Call (720) 806-7634 →Boiler repair and installation for the Victorian, Queen Anne and TB houses, ductless mini-splits for homes with no ducts, furnace repair for converted homes and later ranches, and AC installation planned around the historic district core. Call (720) 806-7634. The house type and the symptom are the two things to have ready.
Around the clock in Montclair. A boiler that quits in a Montclair TB house in a January cold snap or an AC that fails in a July heat wave. Lion Tech Home Services is reachable any hour of the day or night: (720) 806-7634.
In a Montclair home, watch for radiators that heat unevenly, a boiler leaking near its base, rooms that were built as sleeping porches and now swing hot and cold, short cycling, or a top floor that never cools. The age of the house changes which of these shows up first.
Yes. The work here spans the widest mix in Denver: 19th-century Victorians, TB houses, bungalows, Tudor Revival homes and modern ranches, on large lots under grand old trees. No single system describes Montclair, so the plan is drawn up for the era of the house in front of us.
A TB house is a house built for tuberculosis sufferers, with fresh-air sleeping porches and room layouts drawn around open windows and moving air. That envelope fights a modern ducted system: the rooms are arranged for ventilation, not for duct runs, so the plan usually pairs boiler care with ductless cooling rather than forcing ducts through the house. The 1975 historic district covers the central heart of Montclair only, so the address is checked before exterior work is planned.
