Common Types of Air Conditioners

HVAC technicians have the expertise to service most air conditioner models, but knowing more about what you have can be beneficial. Below, we'll explain each of the common AC systems.

  • Split ACs: Split air conditioners have two main elements: one inside and one outside. They provide quiet operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Central AC: These are the most common home air conditioners, offering consistent, precise temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to different rooms in your home.
  • Portable air conditioners: As the name suggests, portable air conditioner systems don't require permanent installation or ductwork. Instead, they remove hot air through an exhaust hose connected to a window or nearby vent. They're popular for apartments, condos, or individual rooms.
  • Ductless mini-split: Ductless mini-split ACs have an exterior unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
  • Window-mounted ACs: Window air conditioners are a popular choice for San Marcos townhomes, apartments, and condos. These budget-friendly, convenient units are designed for cooling single rooms and small spaces, and they fit snugly in a window frame or dedicated wall slot. Many window-mounted AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your San Marcos AC Repair Service

With the sweltering San Marcos heat, AC issues are urgent to fix. However, to get the best possible outcome, it's critical to thoroughly research different HVAC companies first. We recommend adhering to these steps as you prepare.

Confirm the Company Is Properly Licensed and Insured

Texas' Department of Licensing & Regulation issues Air Conditioning and Refrigeration Contractor licenses to both companies and technicians. Applicants for a contractor license must meet apprenticeship requirements unless they hold a technician license, trade school diploma, mechanical engineering degree, or relevant military service experience.

Many states and cities also require companies to carry liability insurance. Even if your community doesn't require it, we still recommend choosing an insured company. This will protect you if an accident happens or something gets damaged.

Read Customer Reviews

Find customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes businesses that handle complaints professionally and honor their warranties.

It's common for even the best AC repair businesses to have both positive and negative reviews. Read each one carefully, and avoid a company if most reviewers had subpar experiences.

Compare Estimates

We advise getting contacting at least three different companies to find the best pricing and offerings. Get a written copy of each quote, and learn more about permitting fees, emergency repair availability, installer guarantees and manufacturer warranties.

Frequently Asked Questions About AC Repair in San Marcos

What's the cost of an AC repair job in San Marcos?

Your AC unit repair costs will hinge on your system's make and model and the malfunctioning part. A basic repair job like sorting out a thermostat might cost $150–$250, whereas a more intricate fix like swapping out the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$62–$165
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,239–$3,717
Fan or air blower issues$150–$200
Compressor replacement$600–$1,569

How often should San Marcos homeowners have their AC systems serviced?

It's a good idea to service your air conditioner at least once a year. You can further maximize its lifespan and efficiency by keeping the outdoor unit clear of brush and debris.

Why should I hire an HVAC professional? Couldn't I repair my air conditioner myself?

You can most likely position a window AC unit without professional help. However, installing other AC units should almost always be done by an HVAC contractor who knows the intricate tubing, piping and wiring. We also advise seeking professional installation due to the risk of refrigerant spills.

How long is my air conditioner's lifespan? When should I consider a replacement?

You won’t need to change air conditioner for 10–15 years with proper maintenance. As your AC ages, its mechanical parts might become hard to find. You'll probably need to consider new AC installation if your company can't install a broken part.

What industry certifications should I look for when researching San Marcos AC repair companies?

Private accreditations might not be required, but companies that seek them are typically more trustworthy. The two largest HVAC trade bodies that issue certifications are the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and Air Conditioning Contractors of America (ACCA).
