Common Types of Air Conditioners

By understanding which type of air conditioner you have, you'll feel more empowered in your provider search. Rochester HVAC technicians have experience with different AC makes and models, and they can adapt their skills to your needs.

  • Ductless mini-split: Ductless mini-splits have an exterior unit and multiple interior units, with no ductwork required. They offer flexible installation options, individual room temperature control, and higher energy efficiency.
  • 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 various rooms in your home.
  • Portable air conditioners: As the name implies, 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.
  • Window ACs: Window air conditioners are a popular choice for Rochester condos, townhomes, and apartments. 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 install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They provide silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.

How to Choose Your Rochester 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

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.

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 respond to complaints professionally and honor their warranties.

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

Compare Estimates

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

How do I know if my air conditioning system needs repair?

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

What month is best for getting an air conditioner replaced?

To find the best time for your installation, consider both local weather patterns and company demand. Generally, contractors get more in demand as the weather warms up and less busy during the cooler months. Therefore, it might be best to get the job done between late September and mid-November or March to mid-May.

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

Private accreditations aren't always necessary, 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).

How quickly can an HVAC company in Rochester respond to emergency repair requests?

Some repair companies offer same-day or next-day service for emergency air conditioner breakdowns. However, the specific timeframe will vary depending on the team's schedule, the terms in your contract, and the severity of the issue. For the most accurate info, we recommend contacting the company directly and explaining the situation.
