Proactive Care, Lower Bills—RGV Wide
Services for Heating Maintenance & Inspection
We perform a thorough tune-up and inspection that improves comfort, protects equipment, and documents system health. After a quick baseline, we clean critical parts, measure performance (not guess), and provide simple, prioritized options—what to fix now versus what to plan later.
Our tune-up & inspection includes:
- Airflow: filter check, return/duct review, blower speed & static pressure measurement
- Gas furnaces + AC/coil (single/two-stage & variable-speed)
- Electric air handlers with heat strips
- Ductless mini-splits (heating & cooling)
- Package units/rooftops (light commercial)
- Smart thermostats (wiring/adapters as needed)
Code items & best practices (as applicable):
- Verify breaker/disconnect/whip sizing and grounding
- Confirm venting/clearances & combustion air; correct PVC condensate routing (90%+)
- Proper drain termination (trap/air gap) and secondary pan where required
- Label access panels; note corrections for inspection readiness
Upgrades & options:
- Deep-clean blower/indoor coil (if impacted)
- High-MERV media cabinet or filter-size correction
- Smart thermostat wiring/C-wire add
- Duct sealing/balancing, added returns
- Surge protection (heat pumps), float switch/secondary pan adds
Airflow, Combustion & Condensate — The Big Three
Reliable heat depends on three fundamentals. Airflow: correct blower speed and low static pressure keep temperature rise in range and prevent limit trips. Combustion/defrost: furnaces need stable gas pressure, proper ignition, and clear venting; heat pumps need clean coils, good charge, and a working defrost cycle to avoid icing. Condensate management: 90+ furnaces and air handlers must drain cleanly—blocked traps and pumps cause shutdowns and water damage. Our heating tune-up measures and fixes these first principles so comfort and efficiency follow.
Know the Warning Signs in the Rio Grande Valley
When to Schedule Heating Maintenance (or Sooner)
Lukewarm air or short-cycling, frequent breaker trips, rooms that never reach setpoint, burning/gas odors, noisy starts or blower squeal, frost that doesn’t clear on a heat pump, water near a 90+ furnace, or rising winter bills are all red flags. If there’s no heat, book repair diagnostics first; if the system runs but underperforms—or it’s been 12 months—schedule a heating maintenance & inspection.

Will call again if I have other electrical problems.Posted on Jennifer CastilloTrustindex verifies that the original source of the review is Google. Great Service: We had a leak and couldn’t figure out where it was coming from. Eduardo took his time to find the source, kept me updated throughout the process, and finally discovered it was an AC leak. Just last week, we had paid another company to fix the same issue, but they didn’t do the job correctly. Eduardo explained everything clearly, offered to correct the problem, and even charged less than what we had previously paid the other company. Once he identified the leak, he made sure it was completely taken care of. I called today, and they arrived in less than an hour—excellent service! Eduardo was the best, and I highly recommend him company.Posted on JoAnn BreauxTrustindex verifies that the original source of the review is Google. Great service, super fast and convenient.

Heating Maintenance & Inspection Questions, Answered
Straightforward answers before you book—symptoms, costs, fixes.
How often should I service my heating system?
At least once per year before cooler weather. Combo systems in dusty or high-use homes may benefit from semi-annual checks.
What’s the difference between maintenance and repair?
Maintenance is preventive cleaning/testing to keep performance and safety in line. Repair targets a fault stopping heat now. If there’s no heat, start with repair diagnostics.
Do you check for carbon-monoxide risks?
We verify combustion air, venting, flame quality, and temperature rise on furnaces and can perform ambient CO checks on request. We also recommend CO detectors near sleeping areas.
Will you adjust refrigerant on a heat pump during maintenance?
Only if performance readings indicate a problem and after addressing leaks or restrictions. We confirm with superheat/subcooling—no blind “top-offs.”
How long does a heating tune-up take?
Typically 60–90 minutes per system, longer if coils are dirty or condensate systems need extra work.
