Your air conditioner ran all last summer without a complaint, so nobody looked at it. Then the first 90-degree day hits and the house won't get below 78. That's usually not a dead unit — that's a dirty coil, a low charge, or a blower moving half the air it should. Ultimate HVAC does central AC tune-ups and maintenance across Skokie, and when you call, you get Chano Garcia and his family. No call center, no subcontractor showing up in a rented van. A real appointment time and a straight answer.
What a central AC tune-up involves
A tune-up isn't a guy spraying the condenser with a hose and handing you an invoice. It's a full check of the boring fundamentals that decide whether your system makes it through a Cook County summer.
We start outside at the condenser: wash the coil properly, straighten bent fins, clear the base of leaves and cottonwood, check the contactor and capacitor for pitting and weak microfarad readings, and verify the disconnect and wiring are tight. Then we move to the indoor side — evaporator coil condition, blower wheel cleanliness, filter size and fit, and the condensate drain and pan, which is the number one cause of the water stain on a Skokie basement ceiling.
From there it's the numbers. We take supply and return temperatures for a proper temperature split, read suction and liquid pressures, calculate superheat or subcooling depending on the metering device, and check amp draw on the compressor and blower motor against the nameplate. We look at static pressure too, because most "weak AC" calls in older Skokie homes are really an airflow and ductwork problem, not a refrigerant problem. You get told what we found, what's fine, and what's going to fail — in that order.
Why Ultimate HVAC for AC tune-ups and maintenance
- Family owned and family run. Chano Garcia and his family do the work. No subcontractors, no rotating crew you've never met, no "press 1 for service."
- $140 seasonal tune-up. That's the current price for a full seasonal maintenance visit — flat, stated up front, no surprise add-ons at the door.
- Same-day service and 24/7 availability. Open Monday through Sunday, emergency calls around the clock. If your AC quits Saturday night, that's still us answering.
- Free second opinions. If another company in the Skokie area told you the whole system has to go, let us look before you write that check.
- We check airflow, not just refrigerant. Sizing, static pressure, and ductwork are where the real problems hide. We measure them instead of guessing.
- Transparent pricing and financing. You see the findings, the options, and the cost before anyone touches a wrench.
Our central AC maintenance process
- You call or book online. You get a firm appointment window, not a vague "sometime Tuesday."
- We ask what the system is actually doing. Short cycling? One hot bedroom? Higher bills? That tells us where to look first.
- Outdoor unit service. Coil cleaning, fin work, electrical inspection, capacitor and contactor testing, amp draw readings.
- Indoor unit service. Blower and evaporator inspection, filter check, condensate drain clearing, pan and float switch verification.
- Performance testing. Temperature split, refrigerant pressures, superheat/subcooling, static pressure, thermostat calibration and cycle test.
- Plain-English report. What's healthy, what's marginal, what needs to be repaired now — with pricing before we proceed.
- Plan for next season. If the system is near end of life, we'll say so honestly and talk through AC and furnace installation options when you're ready — not before.
What a central AC tune-up typically costs
Our seasonal tune-up is $140. That's the maintenance visit itself: the inspection, cleaning, testing, and readings described above, plus a written rundown of what we found. It does not include parts or repairs discovered along the way — a failing capacitor, a seized contactor, a clogged drain line that needs more than a clearing, or refrigerant if the system is genuinely low.
What drives the number up beyond the tune-up: badly neglected coils that need chemical cleaning, hard-to-access attic or crawlspace air handlers, older systems where a part is already on its way out, and airflow problems that trace back to undersized or leaking ductwork. What keeps it down: yearly maintenance, a clean filter changed on schedule, and catching a weak component before it takes the compressor with it.
If a repair is needed, we quote it before we do it. Financing is available on larger work, and second opinions are free. Call for a free quote and we'll give you a real number, not a range designed to get us in the door.

FAQ
How often should I have my central AC tuned up?
Once a year, in spring before you need it. Skokie summers are humid and hard on equipment, and a coil that's been collecting cottonwood since April makes the compressor work for nothing.
My AC is running but the house isn't cooling. Is a tune-up enough?
Sometimes. A dirty coil or clogged filter will do exactly that. But if the temperature split and static pressure readings are off, the problem is airflow or ductwork and we'll tell you straight instead of just topping off refrigerant.
How long does the visit take?
Plan on about an hour to an hour and a half for a standard single system, longer if the coils are heavily fouled or the air handler is in a tight attic space.
Do you service commercial systems?
Yes. We work with small commercial customers in Skokie and around Cook County, including rooftop units and boiler systems on the heating side.
Another company said I need a new system. Will you look at it?
Free second opinion, no pressure. Sometimes the diagnosis is right. Sometimes it's a $60 part.
Can I book without calling?
Yes — schedule online and you'll get a confirmed time. If you'd rather talk to a person, you're talking to the family, not a call center.
