A dirty filter or coil is choking airflow, so the unit works harder, cools less, and pushes your bill up every month it goes unaddressed.

What Does AC Maintenance Actually Cover in San Antonio?
Most San Antonio homeowners don't think about their AC until it stops working, usually on the hottest Saturday of the year, when every HVAC company in the city is already slammed. Regular maintenance is what prevents that call. Before cooling season and before the first cold snap, an Alamo Comfort Heating & Air Conditioning technician inspects the full system, cleans what's dirty, tests what's wearing, and logs the readings. No commission, no manufactured problems, just an honest report and an air conditioner ready for whatever summer brings.
What a Tune-Up Catches Before Summer Does
8 months a yearis roughly how long San Antonio air conditioners run, far past the national average, which is exactly why they wear out faster here.
Twice a yearis how often we service a system: once before cooling season and once before the cold snap, so nothing gets asked to perform cold.
Most no-cool callsin summer trace back to a dirty filter, a clogged condensate drain, or a weak capacitor, all of them caught early on a tune-up.
$119is our flat residential diagnostic if something's already broken, disclosed before we touch anything and credited toward the repair when you move forward.
On the job
01 / When it needs a tune-up
Hear That Hum? Your AC Is Asking for a Tune-Up
You don't have to wait for a full breakdown to know a system is slipping. In a climate that runs the air conditioner most of the year, small faults compound fast, and a tune-up catches them while they're still cheap. Call us if you notice any of these:
Low refrigerant or a fouled coil means it can't keep up, and the strain shortens the life of the compressor, the most expensive part to replace.
A clogged condensate drain is backing up, and the safety float that protects your home can shut the whole system down in the middle of July.
A neglected air conditioner loses efficiency every season, drawing more power for less comfort until someone cleans and tunes it.
That short-cycling is often a failing capacitor or restricted airflow, and catching it now prevents a far costlier compressor failure later.
Filters clog, refrigerant charge drifts, and electrical connections loosen, left alone, those small things line up into a peak-summer failure.
When in doubt, just call. If your AC is running fine, we'll tell you that, tune it up, and get out of your way. If it's quietly slipping, you'll know exactly what's wrong and what it costs before anything gets decided. For a repair that makes more sense than maintenance, see AC Repair in San Antonio, or if the system is genuinely done, AC Installation & Replacement and Heat Pumps are both worth a look.
02 / Tune-up pricing in San Antonio
Transparent AC Tune-Up Pricing in San Antonio
You can book a one-time air conditioner tune-up, or fold both seasonal visits into a maintenance plan. The Davy Crockett Plan is the standard tier and the best-seller, twice-yearly visits and priority scheduling when something breaks. The William B. Travis Plan is the enhanced tier with additional coverage. Either way, what you're paying for is the same full inspection, cleaning, and electrical check, with every reading logged so we track your system over time. If the visit turns up a repair, you approve the price in writing before we start. Call (210) 202-0255 and we'll walk you through which plan fits your system and budget, pricing included.
What a Tune-Up Includes, Not Just a Filter Swap
The Difference Is What Gets Checked
Plenty of “maintenance specials” are a filter change and a quick look. That's not maintenance, it's a sales call with a clipboard. Here's what a full tune-up covers and where the cheap version stops short:
| A quick “filter swap” check | An Alamo Comfort Heating & Air Conditioning tune-up |
|---|---|
| Filter changed, and that's about it | Refrigerant charge, coils, drain, and electrical all checked |
| Eyeballed from across the room | Capacitor and contactor tested under load |
| No record of what was found | System readings logged so we catch wear early |
| A pitch for a new unit at the door | Repair-first findings, in writing, with no pressure |

Cleaned, tuned, logged.
We leave the system running right, change the filter, and record the readings so the next visit starts from a known baseline.
Why homeowners stay
Why San Antonio Homeowners Keep Us on the Calendar
We don't use the visit to upsell you
Our technicians earn no commission on equipment, repairs, or replacements, so a maintenance call is just a maintenance call. If everything checks out, that's what you'll hear. If something needs attention, you see the evidence and approve the price. Nobody here is paid to manufacture a problem or talk you into a system that has years left.
You get the owner, not a call center
Alamo Comfort Heating & Air Conditioning is family-owned, women-owned, and based right here in San Antonio, not a private-equity chain answering to investors in another state. The same family that owns the company name stands behind every job that goes out. That's a different kind of accountability than a corporate call center can offer.
We keep a record, so problems don't surprise you
Because we log your system's readings every visit, we can see a capacitor weakening or a charge slipping before it strands you in the heat. That history is the whole point of regular hvac maintenance. It's something a one-time tune-up from a company that never sees your system again simply can't give you.

What San Antonio Homeowners Say
Across Google reviews, Alamo Comfort Heating & Air Conditioning holds a -star average, and the words San Antonio homeowners use most are “knowledgeable,” “fair pricing,” and “no upcharging.”
How often should I service my AC in San Antonio?
Twice a year, once before cooling season and once before winter. Our climate runs air conditioners about eight months a year, so they wear faster than the typical national maintenance schedule assumes.
Do I need a maintenance plan, or can I book a one-time tune-up?
Either works. A one-time air conditioner tune-up is fine, but a plan covers both seasonal visits and gives you priority scheduling when something breaks during peak heat.
Will a tune-up actually lower my energy bill?
It can. A clean coil, correct refrigerant charge, and fresh filter let the system cool with less runtime, so a neglected unit that's been working overtime usually draws less power after service.
Do you charge a diagnostic fee during maintenance?
A standard tune-up is its own service. If we find a separate problem that needs diagnosing, that's our flat $119 residential fee, disclosed up front and credited toward the repair if you proceed.
What's the difference between your two maintenance plans?
The Davy Crockett Plan is the standard tier and the best-seller, with twice-yearly visits and priority scheduling when something breaks. The William B. Travis Plan is the enhanced tier with additional coverage. Call (210) 202-0255 and we'll walk you through which fits your system and budget, pricing included.
Is Alamo Comfort Heating & Air Conditioning a licensed HVAC contractor?
Yes. We're a licensed Texas HVAC contractor (TACLB 110532E) and EPA-608 certified, so your maintenance is handled by qualified technicians and meets state code.
