Common Types of Air Conditioners

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

  • Portable air conditioners: As the name implies, portable AC 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 popular for condos, apartments, or individual rooms.
  • 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, individual room temperature control, and flexible installation options.
  • Split ACs: Split air conditioner units have two main elements: one indoors and one outdoors. They offer silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window ACs: Window air conditioners are a popular choice for Modesto condos, townhomes, and apartments. 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 air conditioner users set up 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 precise, consistent 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.

How to Choose Your Modesto AC Repair Service

With the oppressive Modesto 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.

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 recognizes contractors that handle complaints effectively and honor their warranties.

It's normal for even the best AC repair businesses to have both positive and negative reviews. Read each one carefully, and avoid a company if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Modesto

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

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–$168
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,262–$3,786
Fan or air blower issues$150–$200
Compressor replacement$600–$1,598

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

What do I do if my AC is running but not cooling?

If your AC is running but not cooling, a blocked condenser coil could be the culprit. Normally, the AC’s condenser fan draws air into the outdoor unit through the condenser coil to extract heat energy from your home. A technician can help by clearing the clog or replacing a damaged coil.

What industry certifications should I look for when researching Modesto AC repair companies?

Private accreditations aren't always necessary, but firms that seek them are typically more trustworthy. The two largest HVAC trade bodies that issue certifications are the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and Air Conditioning Contractors of America (ACCA).
