Common Types of Air Conditioners

There are a few different types of air conditioners on the Round Rock market. While HVAC professionals can work with most types, knowing which one you have will ease your company search.

  • Split ACs: Split ACs have two main elements: one inside and one outside. They offer quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window ACs: Window air conditioners are a popular choice for Round Rock condos, apartments, and townhomes. These compact, affordable units are designed for cooling small spaces and single rooms, 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.
  • Ductless mini-split: Ductless mini-splits have an exterior unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
  • Central AC: These are the most common home air conditioners, offering precise, consistent temperature control. They feature a central unit that cools air from outside, purifies it, and sends it through ducts to various rooms in your home.
  • Portable air conditioners: As the name hints, portable ACs 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 preferred for apartments, condos, or individual rooms.

How to Choose Your Round Rock AC Repair Service

While you might want to resolve your AC issue quickly, you should do some essential research before signing a contract with a repair service. Take the following steps to ensure you find the most suitable company for your home.

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.

You should also check a company has sufficient liability coverage, even if your state doesn't require it. Choosing an insured company will protect you if mishaps arise during work.

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 providers to have both positive and negative reviews. Read each one carefully, and avoid a business if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Round Rock

What's the cost of an AC repair job in Round Rock?

What are some signs that I should call an HVAC repair company?

Here are some of the most frequent AC issues you might face: It's best to contact a professional HVAC technician if you encounter any of these problems.

How often should Round Rock homeowners have their AC systems serviced?

It's a good idea to service your air conditioner at least one time per 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?

Yes, it's better to get a new air conditioner professionally installed. Most units have complex piping and wiring that could stump even a seasoned do-it-yourselfer. They also use chemical coolants that could pose health hazards if they spill or leak. With their training and equipment, the right technician will set you up for success.

How many years until I should replace my AC unit?

You won’t need to buy a new 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.
