No heat in January is an emergency. We treat it like one.
Fast triage when comfort fails, and straight repair-vs-replace math when equipment ages out. Nobody should buy a furnace under panic pricing.
Symptoms we chase down weekly
No heat / weak heat
Igniters, flame sensors, gas valves, boards — furnace triage that starts on the phone.
AC not cooling
Capacitors, contactors, refrigerant issues, or airflow — diagnosed in order of likelihood.
Short-cycling
On-off-on-off kills equipment. Usually sizing, airflow, or controls — all fixable.
Bills creeping up
Efficiency losses show up on the bill before the breakdown. Worth a look before peak season.
Strange noise or smell
Screeches, rattles, and burning smells each mean something specific. Describe it — we’ll narrow it fast.
Rooms that never match
Hot upstairs, cold basement — balancing, returns, or a mini-split where ducts can’t reach.
Replacements without the panic pricing
When equipment truly ages out, you’ll get a load-calculated recommendation with good-better-best options and the actual efficiency math — not a one-size quote with a countdown timer on it.
- Manual-J style sizing — no tonnage guesswork
- Furnaces, ACs, heat pumps, mini-splits, and RTUs
- Electrical scope (circuits, disconnects, surge) included by default
- Permits, inspection, and haul-away handled
- Old-equipment honesty: if a repair buys you years, we say so
HVAC questions, answered straight
Repair or replace — how do you decide?
Age, repair cost vs remaining life, efficiency delta, and parts availability. We show the math and you decide. A 6-year-old furnace with a failed igniter is a repair, not a sales opportunity.
Do you service all brands?
Yes — the physics is the same. Carrier, Trane, Lennox, Goodman, Mitsubishi, Daikin and the rest.
Are mini-splits actually good in Colorado?
Modern cold-climate units heat well below zero and cool efficiently in July — ideal for additions, garages, and homes without ducts. Sizing and placement decide the experience.
Can you handle the electrical for a new unit?
That’s the point of Straightline — circuit, disconnect, controls, and equipment are one scope, one crew, one inspection story.
Comfort emergencies don’t keep office hours.
