Professional Mini Split A/C Installation in Queretaro and Puebla
Certified HVAC technicians, proper vacuum process and 220v electrical prep — so your Inverter unit cools perfectly, runs silently and keeps its manufacturer's warranty valid.
Quick Answer
What a Professional Mini Split Installation Includes
A professional mini split A/C installation includes securely mounting the indoor and outdoor units, routing insulated copper piping, pulling a deep vacuum on the refrigerant lines, and ensuring safe electrical connections. A standard install in Queretaro or Puebla takes 2 to 3 hours. Hiring certified technicians prevents water leaks, ensures maximum cooling efficiency, and is required to protect the manufacturer's warranty on modern Inverter units.
With rising temperatures in Central Mexico, a reliable A/C is no longer a luxury. But buying a high-end Inverter mini split is only half the battle — a rushed installation by an uncertified handyman will ruin the compressor and void the warranty. At Reliable Services México our HVAC crews follow strict manufacturer guidelines so your unit cools perfectly, runs silently and doesn't blow up your CFE bill.
The Hidden Dangers of Cheap A/C Installations
Clients call us in the middle of a heatwave because the "cheap" installer left their brand-new A/C dripping water inside the bedroom — or the unit stopped cooling after just two months. Here's why you should never cut corners:
Skipping the vacuum process
Air and moisture left inside the copper lines acidify the refrigerant and destroy the compressor in under a year.
Improper drainage
If the drain hose isn't sloped correctly, condensation backs up and ruins your interior paint and drywall.
Electrical fire hazards
Plugging a powerful A/C into a regular bedroom outlet overheats the wires and melts the plug.
Voided warranty
Most Inverter manufacturers require certified installers with vacuum gauges — a bad install voids the compressor warranty.

Our Certified Mini Split Installation Process
Our technicians don't guess or improvise. We use specialized tools to ensure your investment lasts for years.
- 1
Site evaluation & electrical check

- 2
Secure mounting
Heavy-duty wall anchors for the indoor evaporator and outdoor brackets (ménsulas) — perfectly level and vibration-free.

Clean drilling
We drill the wall pass-through for the copper lines with minimal dust, then seal it against pests and hot air.

Deep vacuum (crucial)
We connect a professional vacuum pump and digital micron gauge to remove 100% of air and moisture before releasing the R-410A or R-32 refrigerant.

Performance testing
We start the unit, check gas pressure, measure the temperature drop and verify that water drains properly outside.

Frequently Asked Questions
Is it better to buy a 110v or 220v mini split?+
220v units are generally more electrically efficient and put less strain on your wiring, but they require a 220v contract with CFE. If you cannot upgrade your electrical panel, a 110v Inverter unit is your best option.
Does a new mini split come with the outdoor mounting brackets?+
No. New mini splits do not include the metal L-brackets (ménsulas) to hang the motor on an exterior wall. We provide and securely install these brackets to ensure a safe mount.
How often should I have my mini split serviced?+
We highly recommend a professional deep cleaning every 6 months if you use it daily, or at least once a year right before the spring heatwave begins, to ensure clean air and prevent the unit from freezing up.
