Common Types of Air Conditioners

There are a few different types of air conditioners on the Danville market. While HVAC contractors can work with most types, knowing which one you have will simplify your company hunt.

  • 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.
  • Window-mounted ACs: Window air conditioners are a popular choice for Danville apartments, condos, and townhomes. These compact, affordable 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 AC users install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They provide peaceful operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • 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.
  • Ductless mini-split: Ductless mini-splits have an exterior unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.

How to Choose Your Danville AC Repair Service

You likely want a quick solution for your air conditioner's problem. However, before recruiting a repair company, it's important to carefully investigate how well it fits your home's needs. Here are a few essential steps to follow.

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 something gets damaged during work.

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 handle 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 business if most reviewers had subpar experiences.

Compare Estimates

Obtain at least three detailed, written estimates from different providers for the best value. A good estimate should factor in additional fees such as permitting costs. You should also ask about installer guarantees, manufacturer warranties, and the emergency repair process.

Frequently Asked Questions About AC Repair in Danville

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

Your AC repair costs will hinge on the type of unit you have 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$66–$177

Frozen condenser coils$1,328–$3,985

Compressor replacement$600–$1,683

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.

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

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 complicated piping and wiring that can overwhelm 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.

How many years until I should replace my AC unit?

You won’t need to replace air conditioner for 10–15 years with proper maintenance. As your AC grows older, its mechanical parts might become unavailable. You'll probably need to consider new AC installation if your company can't install a broken part.
