An air conditioner is one of the most expensive things in a house, and one of the hardest to judge by just flipping it on. An HVAC inspection in Rio Grande City gives you measured facts about the system before you buy a home, sign a contract or approve a costly replacement. 956 Multi Service performs these evaluations for homes and small commercial buildings across Starr County and nearby Hidalgo County.
You get a written report with photos, so the findings are clear to you, your agent and anyone else involved. Every evaluation includes:
- Age, size and refrigerant type from each data plate.
- Electrical and amp readings against the nameplate.
- Pressures and the temperature drop across the indoor coil.
- Coils, drain, blower, filter and visible attic ducts.
- A heating test, plus a photo report ranked by urgency.
When an inspection makes sense
Most people call us at one of these moments:
- Buying a home. You want to know what condition the AC is in before your option period ends.
- Selling a home. A pre-listing check lets you fix problems on your terms instead of during negotiations.
- A general home inspector flagged the AC. Their report says "further evaluation recommended," and you need someone to evaluate it.
- A replacement quote seems high. You want an independent opinion before committing.
- After a flood or storm. Hurricane Hanna flooded parts of Starr and Hidalgo counties in July 2020, and any unit that has sat in floodwater deserves a check before it runs again.
- Leasing or buying a commercial space. Rooftop units and split systems are often the biggest unknown in a building.
What inspections around Starr County often turn up
Certain findings come up again and again here. Older ranch-style homes may still run R-22, which no longer gets produced. Owner-built additions sometimes share one undersized unit with the original house, or carry a mini-split installed without a proper drain. Manufactured homes can have crushed or torn belly ducts that nobody sees. Condensers beside dirt roads hide caliche-packed coils behind a clean-looking grille, and on low ground near the river, a rust line on the cabinet can show that floodwater once reached it.
Why add an HVAC check to a general home inspection?
A general home inspector covers the whole house in a few hours. For the air conditioner, that usually means confirming it turns on, noting its approximate age and looking for obvious damage. That is useful, but it is not a performance test.
An HVAC evaluation goes further. We put gauges and meters on the system to see how it is actually working, open the panels to inspect parts, and trace problems to their cause. A unit can blow cool air on inspection day and still have a weak compressor or a slow leak.
What we test, system by system
| Area | What we check | Why it matters |
|---|---|---|
| Outdoor unit | Age from the data plate, coil condition, pad level, disconnect and wiring | Age and condition drive remaining life |
| Refrigerant | Type, pressures, line temperatures | R-22 systems rely on reclaimed supply only |
| Electrical | Capacitors, contactor, compressor and fan amp draws | Strain shows up here before failure |
| Indoor unit | Evaporator coil, blower, drain pan, condensate line, filter | Leaks, mold and airflow problems start here |
| Ductwork | Visible attic runs, joints, insulation, sweating | Leaky ducts waste cooling and cause ceiling stains |
| Performance | Temperature drop across the coil, airflow at registers | Shows whether the system really cools the house |
| Heating | Heat strips or heat pump heating mode | Valley cold snaps still happen |
Refrigerant type is worth singling out. US production of R-22 ended in 2020, so an older R-22 system is costly to recharge if it leaks. Newer systems sold since 2025 use lower-impact refrigerants such as R-454B or R-32. Knowing which one a house has helps you plan.
How the inspection visit runs
- Book with your deadline. Give us the option period end date and the number of systems.
- Record the equipment. Data plates are photographed.
- Run and measure. With the system cooling, we read pressures, amps and the temperature drop at the coil and registers.
- Open and look. Panels come off for the electrical parts, coil, drain and blower; accessible attic ducts are traced.
- Test heating. Heat strips or heat pump mode are switched on and checked.
- Write it up. Findings and photos go into the report, ranked by urgency.
Your written report and turnaround
After the visit you receive a report with photos of each component and a plain-language note on what was found. Items are sorted so you can see at a glance what is a safety concern, what needs repair soon and what is simply normal wear.
Turnaround is discussed when you book. If you are working against an option period deadline, tell us the date and we will plan around it as best the schedule allows.
Getting a second opinion on a replacement quote
Replacement quotes vary widely, and the total alone does not tell you much. When we review one, we look at:
- Sizing. Is the tonnage matched to the house, or simply copied from the old unit?
- Efficiency. Texas falls in the federal Southeast region, where new split-system central ACs under 45,000 Btu/h must be at least 14.3 SEER2.
- Refrigerant. Is the new system using a current refrigerant?
- Scope. Are ductwork, the pad, the drain and the thermostat included, or extra?
- Repair option. Could a repair reasonably keep the existing system going?
One more point: equipment installed in 2026 no longer qualifies for the federal 25C energy tax credit, which ended with the 2025 tax year. Ask about utility or manufacturer rebates instead, and talk to a tax professional about your situation. If replacement is the right answer, our AC replacement service can quote it, with no pressure to choose us.
When problems turn up, and who pays
Finding problems is the point of an inspection. If we find something, we explain what it is and, if you ask, give an estimate for the AC repair or replacement. Buyers often use that estimate to negotiate a repair or a price credit with the seller.
The person who books the inspection pays for it. In a home sale that is usually the buyer, though some contracts say otherwise, so check yours. The cost depends on:
- How many systems and mini-split heads are on the property.
- The size of the home or building.
- Attic, roof or crawlspace access.
- Whether ductwork needs a closer look.
- Residential or commercial equipment.
- A return trip if the power or water is off at a vacant house on the first visit.
Repairs found are never part of the inspection fee; they are quoted separately if you ask.
TREC inspectors, TDLR licences and refrigerant rules
Texas splits this work between two agencies. General home inspectors are licensed by the Texas Real Estate Commission, and TREC's standards of practice set what they must test on a cooling system. A/C contractors hold licences from TDLR, the state licensing department, and any of them can be looked up on its website. Gauge readings and any refrigerant recovery fall under EPA Section 608. The length of your option period is set by your contract, not by law, so confirm the date with your agent.

What do buyers and homeowners ask about HVAC inspections?
What do you check during an HVAC inspection?
We record the age and refrigerant type of each system, test electrical parts and motor amp draws, measure pressures and the temperature drop across the indoor coil, and look at the condenser coil, drain pan, condensate line, blower, filter and visible ductwork. Heating is tested too, whether heat strips or a heat pump. Mini-split heads, line sets and error history are included when the home has them.
Can you inspect the AC before I buy a house in Starr County?
Yes, and the best time is during your option period, while you can still negotiate or walk away. Call as soon as your offer is accepted so the visit fits inside your deadline. We need access to the outdoor units, the attic or closet where the air handler sits, and power to the home so the system can actually run.
Do you provide a written report I can give the seller?
Yes. You receive a written report with photos of each component and a plain description of what was found, ranked from safety items to minor wear. It is your report, so you can share it with the seller, your agent or your lender. Turnaround is discussed when you book, so it lines up with your contract dates.
Can you give a second opinion on a replacement quote?
Yes. We look at your existing system and the house, then review the quote for sizing, efficiency rating, refrigerant type, ductwork scope and what is actually included. Sometimes replacement is the right call. Sometimes a repair still makes sense. Either way you get an honest read, and there is no obligation to hire us for the work.
Doesn't my home inspector already check the AC?
Partly. Texas home inspectors licensed by TREC must run the cooling and report the temperature difference between supply and return air, flagging a unit that falls outside roughly 15 to 22 degrees. They do not usually open panels, read refrigerant pressures or test capacitors, which is where an HVAC evaluation picks up.
