How a Service Call Works
A heating service call shouldn't be a black box. Here's what actually happens from the time you call to the time the system is back up.
You Call or Request
Tell us what's happening — no heat, weak heat, error code, or weird noise. A few questions and we'll plan the visit.
Schedule the Visit
Visit window set based on urgency and your availability. Cold-weather no-heat calls get prioritized.
Real Diagnostics
Burners, ignition, gas pressure, airflow, electrical, safeties — actual cause identified before quoting parts.
Review Options
You hear what we found and what your options are — repair, replace, or hold off — with clear pricing before any work begins.
Complete & Verify
Approved work performed, then the system is run and tested to confirm it's actually heating before we leave.
Repair, Tune-Up, or Replace?
There's no universal answer. The right call depends on the system's age, repair history, and how it's been performing. Here's a quick framing — final decisions get made after a real diagnostic.
For most furnace and heat pump issues, a targeted repair is the right answer.
Repair Indicators- System under 10–12 years old
- Issue is isolated (igniter, capacitor, sensor)
- Repair cost is reasonable vs replacement
- System has otherwise been performing
A pre-winter check-up catches small issues before they become no-heat calls during a cold snap.
Tune-Up Indicators- System hasn't been serviced in over a year
- You want peace of mind before winter
- Filter, blower, and gas/electric checks
- Heat exchanger and venting safety check
Replacement may be the better long-term call when the system is past its useful life.
Replacement Indicators- System is 15+ years old with declining output
- Repair costs are stacking up
- Cracked heat exchanger or other safety issue
- Energy bills climbing despite maintenance

All Leander HVAC ServicesHeating and Furnace Services Leander TX FAQs
Common questions homeowners ask about heating service in Leander and surrounding Central Texas. If yours isn't here, just call.
Question not answered here?
Call, email, or send a service request — we'll get back to you.
What kinds of heating systems do you work on?
Gas furnaces, electric heat strips inside air handlers, and heat pumps — all three are common in Central Texas homes. We service, repair, and replace all of them.
How often should a furnace get a tune-up?
Once a year, ideally before the first cold snap. A pre-winter check catches small issues — weak igniters, clogged filters, drifting gas pressure, drain problems — before they turn into a no-heat call at 6am.
My furnace turns on, then off again right away. What's wrong?
That's called short cycling, and it has several possible causes — flame sensor, limit switch, airflow restriction, oversized system, or thermostat issue. A diagnostic call will identify which one is actually happening on your system.
Should I repair my old furnace or replace it?
Depends on the age and what's wrong. Under 12 years old with a single fixable issue, repair usually wins. Past 15 years with stacking repair costs or a cracked heat exchanger, replacement starts to make more sense. We'll lay out the options after the diagnostic — see HVAC Replacement for the full system path.
Are heat pumps a good fit for Central Texas?
Yes — Central Texas winters are mild enough that heat pumps run efficiently most of the time, with backup electric or gas heat covering the few really cold days. Read more on our Heat Pump Services page.
Is DMO Mechanical licensed and insured?
Yes. DMO Mechanical LLC is a licensed Texas HVAC contractor — license number TACLB127781E — covering both residential and commercial work statewide.
