Common Types of Air Conditioners

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

  • Split ACs: Split air conditioners have two main elements: one indoors and one outdoors. They offer quiet operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • 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 preferred for apartments, condos, or individual rooms.
  • Window ACs: Window air conditioners are a popular choice for Waterloo townhomes, apartments, and condos. These compact, affordable units are designed for cooling single rooms and small spaces, and they fit snugly in a window frame or dedicated wall slot. Many window AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Central AC: These are the most common residential AC systems, offering consistent, precise temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to various rooms in your home.
  • Ductless mini-split: Ductless mini-split AC systems have an outdoor unit and multiple interior units, with no ductwork required. They offer individual room temperature control, flexible installation options, and higher energy efficiency.

How to Choose Your Waterloo AC Repair Service

While you might want to resolve your AC issue quickly, you should carefully investigate what's out there before hiring a repair service. Take the following steps to ensure you find the top-rated company for your home.

Confirm the Company Is Properly Licensed and Insured

Iowa's Plumbing & Mechanical Systems Board licenses hydronic, refrigeration, HVAC, and sheet metal contractors. Apprentices, journeymen, and master technicians need individual licenses, but "helpers" under a journeyman or master do not.

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 contractors that handle complaints professionally and honor their warranties.

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

Compare Estimates

Obtain at least three detailed, written estimates from different providers for the best value. A good estimate should include additional fees such as permitting costs. You should also ask about the emergency repair process, manufacturer warranties, and installer guarantees.
