AC Tune-Ups in Matthews, NC and the Charlotte Metro Area
MTB Mechanical serves homes in Matthews, Charlotte, and the surrounding metro in both Carolinas with AC tune-ups built around recorded readings. Our expert technicians clean the system, replace the filter with one we supply, and record how your air conditioner is performing. Charlotte has trusted our expertise in comfort and care for over 20 years. You can schedule your MTB Mechanical AC tune-up online, over the phone, or in the 24/7 website chat.
The science of comfort starts with data, and a cooling system produces plenty of it. Superheat, subcooling, and entering and leaving temperatures tell a technician what a system is doing. The science of comfort is measurable, and the tune-up is how we get it right.

What the MTB Mechanical AC Tune-Up Includes
The checklist pairs cleaning and testing with recorded measurements:
- Filters are supplied and swapped at every visit; one-inch filters are standard, with media and specialty options at additional cost.
- Water and coil cleaner go on the outdoor condenser coil as a rinse.
- Superheat is measured, and superheat and subcooling are recorded, which verifies the refrigerant charge precisely.
- Entering and leaving air temperatures are recorded, the before-and-after numbers that define cooling output.
- Our technician flushes the condensate drain to protect against overflow and inspects the evaporator coil when it is accessible.
- Capacitors, both start and run, get inspected, and the contactors get cleaned.
- Motors are metered for voltage and amperage and tested for worn bearings.
- Lubrication reaches the moving parts, the blower motor and belt get a check, electrical connections are tightened, and every control is safety tested.
- The visible ductwork is inspected, and the temperature drop from return to supply is tested with blower speed adjusted if needed.
Why Precise Readings Matter
A system can pass a visual inspection while its readings drift out of specification. Recorded superheat and subcooling show a charge moving away from correct, recorded entering and leaving temperatures show output declining, and comparing readings from year to year turns both into a trend.
The ductwork inspection follows the same logic, because MTB looks at the home as a system: equipment, airflow, and distribution together. A well-maintained unit feeding leaky ducts still delivers less than it should, and the inspection shows whether the ducts are part of the picture. Regular maintenance also keeps your system in compliance with manufacturer maintenance requirements.
Why Charlotte Chooses MTB Mechanical
Our expert technicians both fix existing systems and design new ones, so a reading that is off gets explained at the systems level, not just the parts level. Pricing is by the job and upfront, not hourly.
A tune-up finding moves directly to our air conditioning repair team, and when a system has reached the end of its life, the same design expertise sizes its replacement through a load calculation rather than a guess. Scheduling is available online, through 24/7 website chat, or by phone.

FAQs
What does by-the-job pricing mean for a maintenance visit?
It means the price is set by the job, stated upfront, and not by the hour. The same pricing applies to any repair the tune-up recommends.
What do entering and leaving temperatures tell you?
Together they measure the work the system performed on your air in a single pass. A healthy split falls in a known range; a narrow split points toward charge or coil problems, and a wide one toward airflow restriction. Recording both at every visit turns a one-day reading into a trend we can act on early.
My house was cooled fine by this system five years ago but struggles now. Why?
Something changed, and the readings show where to look: declining output shows in the temperature split, charge drift shows in superheat and subcooling, and airflow loss shows in the ductwork inspection. If the equipment checks out, our design expertise can look at whether the home has changed.
