Common Types of Air Conditioners

There are a few different types of air conditioning units on the Duluth market. While HVAC professionals can work with most types, knowing which one you have will streamline your company search.

  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They provide silent operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for Duluth townhomes, condos, and apartments. 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-mounted air conditioner users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Portable air conditioners: As the name implies, portable air conditioner units 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 a common choice for condos, apartments, or individual rooms.
  • Central AC: These are the most common residential AC systems, 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.
  • Ductless mini-split: Ductless mini-split air conditioner units have an outdoor unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.

How to Choose Your Duluth AC Repair Service

You likely want a swift resolution for your air conditioner's problem. However, before engaging with a repair company, it's important to do careful research to ensure it's the best for your home. Here are a few essential steps to follow.

Confirm the Company Is Properly Licensed and Insured

In Minnesota, HVAC companies are legally "mechanical contractors." The Department of Labor and Industry nonetheless requires them to register and carry at least a $25,000 bond. Further, while they don't need state licenses, they must comply with local licensing requirements in their service area. We encourage you to contact your city and county governments for more information.

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

Read Customer Reviews

Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits contractors that resolve complaints effectively and honor their warranties.

It's normal for even the best AC repair companies 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 price. A good estimate should list additional fees such as permitting costs. You should also ask about installer guarantees, the emergency repair process, and manufacturer warranties.
