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 describe each of the common AC systems.
- Split ACs: Split AC systems have two main elements: one inside and one outside. They provide peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
- Portable air conditioners: As the name implies, portable air conditioners 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 different rooms in your home.
- Window ACs: Window air conditioners are a popular choice for Greenfield condos, townhomes, and apartments. 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 AC users install their units without professional assistance, though technicians can still help with maintenance and repairs.
- Ductless mini-split: Ductless mini-split ACs 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 Greenfield 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 reliable company for your home.
Confirm the Company Is Properly Licensed and Insured
Wisconsin HVAC contractors are licensed through the Department of Safety and Professional Services. Even with this license, an HVAC company must still subcontract electrical and plumbing work.
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 accredits contractors that respond to complaints professionally and honor their warranties.
It's normal for even the best AC repair providers to have both positive and negative reviews. Read each one carefully, and avoid a provider if most reviewers had subpar experiences.
Compare Estimates
We recommend getting at least three different estimates to find the best cost and services. Get a written copy of each quote, and learn more about installer guarantees, permitting fees, emergency repair availability and manufacturer warranties.
