Common Types of Air Conditioners

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

  • Portable air conditioners: As the name hints, 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.
  • Central AC: These are the most common residential AC systems, offering precise, consistent 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-splits have an exterior unit and multiple interior units, with no ductwork required. They offer individual room temperature control, higher energy efficiency, and flexible installation options.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They offer peaceful operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for Union 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 set up their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Union 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 take the time to research if they're ideal for your dwelling. 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

Check customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes businesses that handle 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 companies for the best value. A good estimate should list additional fees such as permitting costs. You should also ask about the emergency repair process, manufacturer warranties, and installer guarantees.

Frequently Asked Questions About AC Repair in Union

What's the cost of an AC repair job in Union?

Your AC 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 swapping out the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$61–$163
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,225–$3,675
Fan or air blower issues$150–$200
Compressor replacement$600–$1,551

Does my air conditioner need routine maintenance? If so, how often?

It's a good idea to service your AC at least annually. You can further maximize its efficiency and lifespan by keeping the outdoor unit clear of brush and debris.

Is hiring an HVAC company better than doing the repair on my own?

Yes, it's better to get a new air conditioner professionally installed. Most units use complicated piping and wiring that can confuse even a seasoned do-it-yourselfer. They also use chemical coolants that could pose health hazards if they spill or leak. With their training and equipment, the right technician will set you up for success.

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

Private accreditations might not be required, but contractors 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 Union respond to emergency repair requests?

The response time can vary by company, but HVAC companies strive to handle emergency repair requests as quickly as possible. Some companies offer same-day or next-day service for these issues. While a specific timeframe might be listed in your contract, contacting the provider directly is best so you can get the most accurate information.
