Common Types of Air Conditioners

By understanding which type of air conditioner you have, you'll feel more empowered in your contractor search. Reston HVAC technicians have experience with different AC makes and models, and they can tailor their skills to your needs.

  • Window-mounted ACs: Window air conditioners are a popular choice for Reston condos, apartments, and townhomes. These budget-friendly, convenient units are designed for cooling small spaces and single rooms, 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.
  • Central AC: These are the most common residential AC systems, offering consistent, precise temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to various rooms in your home.
  • Portable air conditioners: As the name suggests, 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 a common choice for apartments, condos, or individual rooms.
  • Ductless mini-split: Ductless mini-splits have an outdoor unit and one or more indoor units, with no ductwork required. They offer individual room temperature control, flexible installation options, and higher energy efficiency.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They offer quiet operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.

How to Choose Your Reston AC Repair Service

With the oppressive Reston heat, AC issues are urgent to fix. However, to get the best possible outcome, it's critical to thoroughly research different HVAC companies first. We recommend adhering to these steps as you prepare.

Confirm the Company Is Properly Licensed and Insured

The Virginia Department of Professional and Occupational Regulation issues HVAC licenses at the apprentice, journeyman, master, and contractor levels.

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

Read Customer Reviews

Check 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 provider if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Reston

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

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$64–$170
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$85–$213
Refrigerant leak$400–$1500
Frozen condenser coils$1,279–$3,836
Fan or air blower issues$150–$200
Compressor replacement$600–$1,620

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

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

What month is best for getting an air conditioner replaced?

The best time to replace HVAC systems is during the off-season, when there's less demand for HVAC technicians and costs are cheaper. With Reston's weather patterns, this is usually between late September and the middle of November or early March to mid-May.

Why is my AC running but not cooling?

If your air conditioner is running but not cooling, a technician 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 blockage might be all that's necessary to get your AC back on track.

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 wiring and piping that could stump even a seasoned 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.
