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

  • Split ACs: Split AC systems have two main elements: one inside and one outside. They offer quiet operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Ductless mini-split: Ductless mini-split ACs 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.
  • 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.
  • Portable air conditioners: As the name suggests, 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 popular for apartments, condos, or individual rooms.
  • Window-mounted ACs: Window air conditioners are a popular choice for Union City townhomes, apartments, and condos. 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 AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Union City AC Repair Service

With the sweltering Union City 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

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.

You should also confirm 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

Read 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 common for even the best AC repair providers to have both positive and negative reviews. Read each one carefully, and avoid a business 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, manufacturer warranties and emergency repair availability.

Frequently Asked Questions About AC Repair in Union City

How much can I expect to pay for AC repair in Union City?

Your air conditioner 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 changing the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$69–$183
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$92–$229
Refrigerant leak$400–$1500
Frozen condenser coils$1,375–$4,124
Fan or air blower issues$150–$200
Compressor replacement$600–$1,741

What month is best for getting an air conditioner replaced?

To find the best time for your installation, consider both the local weather and company demand. Generally, contractors are busier as the weather warms up and less busy during the cooler months. Therefore, it might be best to get the job done between late September and mid-November or 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. Removing the blockage might be all that's necessary to get your AC cooling again.

Why should I hire an HVAC professional? Couldn't I repair my air conditioner myself?

You can most likely set up a window AC unit on your own. However, installing other air conditioners should almost always be done by an HVAC contractor who knows the complex tubing, wiring and piping. We also advise seeking professional installation due to the danger of refrigerant spills.

How quickly can an HVAC company in Union City 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 company directly and explaining the situation.
