This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

Common Types of Air Conditioners

By knowing which type of air conditioner you have, you'll feel more confident in your contractor search. Lockport HVAC professionals have experience with different AC makes and models, and they can adapt their skills to your needs.

  • Ductless mini-split: Ductless mini-split air conditioner units have an exterior unit and one or more indoor units, with no ductwork required. They offer flexible installation options, individual room temperature control, and higher energy efficiency.
  • Window-mounted ACs: Window air conditioners are a popular choice for Lockport apartments, condos, and townhomes. 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 air conditioner users install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • 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 different rooms in your home.
  • 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 preferred for condos, apartments, or individual rooms.
  • Split ACs: Split air conditioner units have two main elements: one indoors and one outdoors. They offer silent operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.

How to Choose Your Lockport AC Repair Service

While you might want to resolve your AC issue quickly, you should do some essential research before committing to 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

There's no state HVAC license in the Land of Lincoln. Instead, cities and counties are free to set their own requirements and regulations. Check with your local building department 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 accredits contractors that respond to complaints professionally 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 price. A good estimate should include additional fees such as permitting costs. You should also ask about manufacturer warranties, installer guarantees, and the emergency repair process.

What are some signs that I should call an HVAC repair company?

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

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 use complex piping and wiring that can confuse even an experienced do-it-yourselfer. They also use chemical coolants that could pose serious safety risks 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 Lockport AC repair companies?

Private accreditations might not be required, but businesses 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 Lockport 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 provider directly and explaining the situation.
