Common Types of Air Conditioners

HVAC technicians have the expertise to service most air conditioner varieties, but knowing more about what you have can be beneficial. Below, we'll explain each of the common AC systems.

  • 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 individual room temperature control, flexible installation options, and higher energy efficiency.
  • Central AC: These are the most common residential AC systems, 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.
  • 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.
  • Split ACs: Split AC systems have two main elements: one inside and one outside. They offer peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for Riverhead apartments, townhomes, and condos. 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 deploy their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Riverhead AC Repair Service

You likely want a swift resolution for your air conditioner's problem. However, before recruiting 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

The New York state government doesn't require HVAC companies to get a state license. However, it's common for local governments to require licenses. You should ask your city offices about what's required where you live.

You should also check a company has sufficient liability coverage, even if your state doesn't require it. Choosing an insured company will protect you if mishaps arise during work.

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 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 company if most reviewers had subpar experiences.

Compare Estimates

We recommend getting contacting at least three different companies to find the best pricing and offerings. Get a written copy of each quote, and learn more about manufacturer warranties, permitting fees, emergency repair availability and installer guarantees.

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

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

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 lifespan and efficiency by keeping the outdoor unit clear of brush and debris.

Why is my AC running but not cooling?

If your air conditioner is running but not cooling, a contractor will usually check the condenser coil first. Normally, the outdoor unit fans draw air into the coil so the system can extract heat energy from your home. Clearing the clog might be all that's necessary to get your AC working again.

How many years until I should replace my AC unit?

With proper care, your air conditioner's lifespan could be 10-15 years. Remember that parts often become obsolete as time goes on. If your installer can't find a critical replacement part, you might need to consider getting a new air conditioner.
