Common Types of Air Conditioners

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

  • Ductless mini-split: Ductless mini-split AC systems have an exterior unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, flexible installation options, and individual room temperature control.
  • Central AC: These are the most common home air conditioners, offering consistent, precise 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.
  • Split ACs: Split AC systems have two main elements: one inside and one outside. They offer peaceful operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window ACs: Window air conditioners are a popular choice for Hamilton 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 AC users install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • 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 popular for apartments, condos, or individual rooms.

How to Choose Your Hamilton AC Repair Service

You likely want a quick solution for your air conditioner's problem. However, before hiring 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

Ohio's Construction Industry Licensing Board licenses and regulates HVAC and refrigeration companies throughout the state. We recommend verifying a company's licensing information by visiting the Board's website.

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 businesses that resolve complaints effectively 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

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

Frequently Asked Questions About AC Repair in Hamilton

How much can I expect to pay for AC repair in Hamilton?

Your AC system repair costs will hinge on your system's make and model and the malfunctioning part. A basic repair job like sorting out a thermostat might cost $150–$250, whereas a more intricate fix like replacing the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$61–$162
Electrical circuits$200–$250

Refrigerant leak$400–$1500
Frozen condenser coils$1,212–$3,635
Fan or air blower issues$150–$200
Compressor replacement$600–$1,535

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

Here are several 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.

When is the best time to replace an AC unit?

To determine the best time for your installation, consider both Hamilton's temperatures and company demand. Generally, contractors are more in demand as the climate 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 do I do if my AC is running but not cooling?

If your AC is running but not cooling, a blocked condenser coil could be the culprit. Normally, the AC’s condenser fan pulls air into the outdoor unit through the condenser coil to extract heat energy from your home. A technician can help by clearing the clog or replacing a damaged coil.

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 can overwhelm even a seasoned do-it-yourselfer. They also use chemical coolants that could pose dangers if they spill or leak. With their training and equipment, the right technician will set you up for success.
