Common Types of Air Conditioners

There are a few different varieties of air conditioning units on the Simi Valley market. While HVAC technicians can work with most types, knowing which one you have will simplify your company research.

  • Ductless mini-split: Ductless mini-split AC systems have an exterior unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, flexible installation options, and individual room temperature control.
  • Window-mounted ACs: Window air conditioners are a popular choice for Simi Valley condos, townhomes, and apartments. 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 AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Central AC: These are the most common home air conditioners, offering consistent, precise temperature control. They feature a central unit that cools air from outside, purifies it, and sends it through ducts to different rooms in your home.
  • Portable air conditioners: As the name suggests, portable air conditioner systems 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 ACs have two main elements: one indoors and one outdoors. They provide peaceful operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.

How to Choose Your Simi Valley AC Repair Service

You likely want a quick solution for your air conditioner's problem. However, before signing up with 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

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 accidents happen 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 contractors that respond to complaints professionally 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 suggest getting at least three different quotes to find the best pricing and offerings. Get a written copy of each quote, and learn more about manufacturer warranties, installer guarantees, emergency repair availability and permitting fees.

Frequently Asked Questions About AC Repair in Simi Valley

How much can I expect to pay for AC repair in Simi Valley?

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 changing the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$63–$169
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,268–$3,805
Fan or air blower issues$150–$200
Compressor replacement$600–$1,607

How often should Simi Valley homeowners have their AC systems serviced?

Homeowners should have their AC systems serviced a minimum of once a year to ensure optimal performance. This usually involves cleaning the outdoor unit of brush and debris. Regular servicing can help to maintain the system's efficiency and prolong its lifespan.

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

How many years until I should replace my AC unit?

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

How quickly can an HVAC company in Simi Valley respond to emergency repair requests?

The response time can vary by company, but HVAC companies strive to handle emergency repair requests as quickly as possible. A number of companies offer same-day or next-day service for these issues. While a specific timeframe might be listed in your contract, contacting the company directly is best so you can get the most accurate information.
