Heating
Furnace repair, boilers and radiant heat
Most of the metro will only touch forced air. Boilers, baseboard and in-floor hydronic heat are work Atlas actually does, which matters in older Littleton and Lone Tree homes where that is what is installed. Gas equipment also has to be set for Colorado altitude, and a system charged off a generic sea-level chart underperforms here even when nothing is broken. Atlas is based in Lone Tree, and heating, cooling and plumbing in Lone Tree covers the neighborhoods there.

Cooling
Air conditioning and evaporative coolers
Front Range summers are hard on equipment in a way that catches people out. Thinner air at this elevation carries less heat per cubic foot, so airflow and charge have to be set for altitude. Evaporative coolers thrive in the dry stretch and then struggle through monsoon season, which is usually when people start asking whether to repair or convert.
AC repair
Capacitors, condenser coils, refrigerant leaks found rather than topped off, frozen coils. AC repair →
AC installation
Central air and heat pump replacement, sized correctly for the home. See AC installation →
Swamp cooler service
Evaporative cooler repair, spring startup, fall winterization and AC conversion. Swamp cooler vs AC →
Mini splits
Ductless systems serviced, repaired and installed.
Air balancing
Rooms that are always too hot or too cold are usually airflow, not the furnace. We measure and adjust rather than guess at dampers. Why AC struggles here →
Whole-home humidifiers
Front Range air is dry enough all winter to dry out floors, furniture and sinuses.
Plumbing & water heaters
Water heaters and residential plumbing
Jared holds an active Colorado journeyman plumbing license, so water heaters and plumbing repairs happen on the same visit as the HVAC work instead of becoming a second appointment with a second company. Colorado water is hard on tanks, which is why lifespan here tends to run shorter than the sticker suggests.
Water heater repair
No hot water, pilot and thermocouple faults, leaks and pressure problems.
Water heater replacement
Tank replacement with new lines, gas and venting done properly. How long they last here →
Tankless installation
Tankless upgrades including the gas and venting the conversion actually needs.
Plumbing repairs
Leaks, fixtures, shut-offs, disposals and general residential plumbing.
Drain and vent work
Drain, waste and vent rough-in on remodels and additions.
Rental properties
Several long-term clients are landlords who call us across their units, not just their own home. Apartments, condos and HOAs →
How a visit works
Diagnose first, price second, work third
You call or text and reach Erica or Jared. Never a call center, never a rotating crew.
We find out what is actually wrong. A lot of people call with a diagnosis they already have, from another contractor or worked out themselves, and it is often close but not exactly right. Confirming it first is what keeps you from paying to replace a part that was never the problem.
You get a flat-rate price before anything starts. You approve the number first. No hourly meter, no commission-driven price book.
The person who diagnosed it does the repair. Jared does the work himself, so nothing gets lost between the person who looked at it and the person who fixes it.
Something not working right?
Call or text early in the day for the best chance at a same-day slot. We answer until 9 PM, seven days a week.
