About this service
Residential HVAC in Denver: What We Do in Homes
Residential HVAC is the heating and cooling of a home, furnaces, boilers, heat pumps, air conditioners, ductwork, and thermostats, repaired, maintained, and installed by Lion Tech Home Services, working on the house as a whole system rather than as separate boxes.
Denver homes are not all the same. A 1920s bungalow with radiators, a mid-century ranch with ducts, and a newer build with a tight envelope each need different thinking. The common thread is the climate: cold winters, hot dry summers, thin air at altitude, and dust and smoke in the mix. The work follows the system the house has, with an honest word on when a repair makes sense and when replacement does.

What's included
What Our Residential HVAC Work Includes
Lion Tech Home Services looks after the whole home system, heating, cooling, ducts, and controls together.
✓
Heating repair and install
Furnaces, boilers, and heat pumps are repaired when they fail, replaced when they are at the end of their life, and sized from a load calculation.
✓
Cooling repair and install
Central AC and heat pumps provide cooling, with ductwork and airflow checked so the cool air reaches every room.
✓
Ductwork
Duct repair, sealing, and installation make sure the air the system heats or cools actually arrives where it should.
✓
Maintenance visits
Seasonal checks cover furnaces, AC, heat pumps, and boilers, coils, filters, controls, and safety checks before each season.
✓
Indoor air quality
Whole-home filtration, humidifiers, and UV for the coil are matched to Denver's dry winters and smoke season.
✓
Thermostats and controls
Thermostat replacement and setup are covered, including zoning controls for homes with rooms that never agree.
How it works
How Residential HVAC Work Goes
01
Call and describe it
Say what is happening: no heat, no cool, a noise, a smell, or a room that never gets comfortable.
02
Visit and test
The system is tested in order, power, controls, airflow, and the equipment itself, to find the fault or the cause.
03
Explain the options
Repair or replacement options are laid out in plain terms, including what each one will and will not fix.
04
Do the work
Equipment is repaired, maintained, or installed, and tested room by room before the visit ends.
05
Leave a note
A note is left of what was done and what to watch for, so the next visit starts from what is already known.
Tools & methods
Tools and Methods We Use
Testing instruments that find the fault in the whole system, not just the part that is loudest.
Manifold gauge set
Reads refrigerant pressures on AC and heat pump work to find leaks and charge problems.
Multimeter
Tests power, controls, and safety circuits across furnaces, boilers, and heat pumps.
Airflow meter
Measures air at the registers so duct and balance problems are found, not guessed at.
Combustion check
Tests burner operation and venting on gas furnaces and boilers.
Inspection camera
Sees inside ducts and tight spaces to find faults without opening walls.
Thermometer and humidity checks
Confirms the system is heating, cooling, and humidifying as it should.
Typical jobs
Before and After
A home with two aging systems
Before
A house ran a worn furnace and an aging AC, each needing attention in its own season, and the upstairs never cooled properly in July.
After
A heat pump now heats and cools the whole house, the ducts were sealed where they leaked, and the upstairs holds temperature.
Radiators and no cooling
Before
A bungalow with radiators had good winter heat and nothing for summer. Window units were loud and only covered two rooms.
After
Ductless zones now cool the bedrooms quietly, and the radiators stay for winter. The window units came out.
A home that never felt even
Before
A two-storey home had rooms that ran hot and cold whatever the thermostat said, and the family had given up on the back bedrooms.
After
Duct repairs, sealing, and balancing evened the rooms out, and the back bedrooms are comfortable again.
Problems we solve
Problems Residential HVAC Work Solves
Home comfort problems usually have a cause in the system. These are the calls that come in most from Denver homes.
Ask a pro →↗
No cool in summer
An AC or heat pump that stops cooling in a heat wave leaves the house unlivable. Call and describe what the system is doing.
Rooms that never agree
Hot and cold rooms usually mean duct or balance problems. Airflow is tested room by room and the runs that are starving are fixed.
Dry air and dust
Denver's dry winters and dusty summers show up indoors. Whole-home filtration and humidification take both on through the system.

“Martin was great! Timely, knowledgeable, and his experience showed. He was able to fix our HVAC that had been having trouble on and off for awhile. Pricing was good and reasonable! Would certainly recommend!”

✓ VerifiedFurnaces, boilers, heat pumps, central AC, ductless mini-splits, ductwork, and thermostats, repaired, maintained, and installed in Denver homes.
Yes. Many Denver homes are older, with radiators, baseboard heat, or ductwork added over decades. The work follows the system the house has, with an honest word on what it needs.
It depends on the age of the system, the cost of the repair, and how often it has needed work. The fault and the options are explained, so repair can be weighed against replacement with the facts in front of the homeowner.
Yes. Heating, cooling, and ducts are one system in a home, and all of it is worked on, so a duct problem is not passed off as an equipment problem, or the other way round.
