Common Types of Air Conditioners

By understanding which type of air conditionermodel you have, you'll feel more confident in your company search. Napa HVAC technicians have experience with different AC makes and models, and they can customize their skills to your needs.

  • Window-mounted ACs: Window air conditioners are a popular choice for Napa apartments, townhomes, and condos. These compact, affordable 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 air conditioner users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Portable air conditioners: As the name implies, portable AC units 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 condos, apartments, or individual rooms.
  • Split ACs: Split air conditioner units have two main elements: one inside and one outside. They offer quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Central AC: These are the most common home air conditioners, 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.
  • Ductless mini-split: Ductless mini-split air conditioner systems have an outdoor unit and one or more indoor units, with no ductwork required. They offer flexible installation options, individual room temperature control, and higher energy efficiency.

How to Choose Your Napa AC Repair Service

With Napa's extreme heat, AC problems are urgent to fix for your comfort and safety. However, don't race to sign a contract until you're convinced a company is the best fit for you. We recommend following these steps in your research.

Confirm the Company Is Properly Licensed and Insured

California HVAC contractors need a C-20 (Warm-Air Heating, Ventilation, and Air-Conditioning) license from the Department of Consumer Affairs. The application process involves comprehensive exams on business law and practical skills.

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

Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits businesses that respond to complaints effectively and honor their warranties.

It's common for even the best AC repair providers 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 permitting fees, installer guarantees, manufacturer warranties and emergency repair availability.

Frequently Asked Questions About AC Repair in Napa

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

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 switching out the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$70–$187
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,399–$4,196
Fan or air blower issues$150–$200
Compressor replacement$600–$1,772

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

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

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 Napa's hot average highs, the off season will usually be in the winter months when temperatures start to drop.

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. Removing the obstruction might be all that's necessary to get your AC working again.

How long is my air conditioner's lifespan? When should I consider a replacement?

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