Why Won’t My Air Conditioner Turn On? Check These 6 Things

Why Won’t My Air Conditioner Turn On? Check These 6 Things

Summer is here, and the need for efficient air conditioners comes with the hot weather. If your air conditioner isn’t kicking on, it can create an uncomfortable and frustrating situation. Fortunately, figuring out why your air conditioner won’t turn on can be as simple as checking a few things. If you require a professional to inspect your system, contact Air Rite to schedule an air conditioner repair in San Luis Obispo. Our expert AC technician will identify the problem and resolve it promptly.

Here Are 6 Things To Check To Get Your AC Up And Running:

Thermostat Settings

First, check your thermostat settings. Ensure it is set to cool mode, the temperature setting is lower than the current temperature, and the fan is set to auto. Check that the display is accurate and up to date, as an incorrect display can cause the AC unit not to operate correctly. Replace any batteries if necessary, as these often cause lost power or a blank display. If your thermostat has a switch for emergency heating, ensure that it’s in the ‘off’ position.

Power Switch

Check that the power switch near or on your indoor unit has not been accidentally turned off. If this switch is off, all power to the unit will be cut off. Check that the cord connected to your outdoor unit is firmly plugged into its outlet; unplugging and replugging this cord can sometimes resolve issues regarding power.


Dirty filters are one of the most common causes of inefficient cooling systems, as they can restrict airflow, which prevents the system from operating properly. When cleaning or replacing filters, make sure you follow manufacturer instructions carefully. Make sure you wash reusable filters with soapy water before reinstalling them back into your HVAC system – it may also be worth investing in new filters if yours are more than six months old due to their reduced efficiency over time. When you schedule AC replacement in Paso Robles with us, our technicians will find you the best durable filters for your AC system.

Fuses & Circuit Breakers

Your AC may not receive power due to blown fuses or tripped circuit breakers. Check both at your main electrical panel for any signs of damage or tripped switches and replace/reset if necessary. Inspect all wires and other components for wear or damage – replace any worn or damaged parts with components approved by the manufacturer. If you have recently had electrical work done on your home – such as replacing a light fixture – check around these areas for loose wiring, which could potentially be causing an issue with your AC unit’s power supply. Do not fix the circuit breaker on your own. Search for AC repair near me and schedule service with the experts at Air Rite.

Refrigerant Leaks

Low refrigerant levels prevent an AC unit from operating correctly, so check for leaks in hoses and connections before doing anything else. Look for signs of corrosion or oil deposits on pipes which could indicate a leak, as well as unusual noises coming from within your air conditioning unit itself. You’ll want a professional technician from Rite to inspect these items if you suspect a refrigerant leak because handling refrigerants requires special licenses and equipment. Do not let this issue prolong as it will cause severe damage, call us for air conditioner repair in Paso Robles. Search for air conditioner repair near me to find our information online.

Compressor and Fan Motors

If none of the other steps resolve the issue, you may have a problem with the compressor motor or fan motor inside your air conditioner unit. Start by checking each item visually – look for burnt-out capacitors, corroded terminals, or melted insulation concerning these parts should they be visible outside their housing units. This typically requires a trained technician with experience HVAC repair in Paso Robles units who can test these items individually with specialized tools like pressure gauges, thermometers, and amp meters during diagnostics testing.

As the caretaker for a senior gentleman in Atascadero, I was concerned for his health and safety during a recent cold snap. I called Air Rite, explained the situation and they made getting my patient’s needs taken care of a priority. The service technician was knowledgeable and professional, going above and beyond and taking the time to listen to my patient’s own diagnosis. The heating repair was completed within an hour and the price was right. I will recommend Air Rite Heating and Cooling to both my patients and my friends.

“Let me tell you why this company should have “10” stars. First, you need to know we had attempted to get our forced air heating fixed by another company from Templeton (posted a review on their site). After waiting several days for the other company to return after their initial visit (said they needed to order a part). After many cold days without even a call back we called “Air Rite” in Atascadero. We spoke with Rick (the owner of the company) and explained our dilemma and frustration with our attempt to get it fixed. He understood and said a ...

“Great service at a great price. When my parents needed an entirely new heater system Air Rite took care of it. When our heater recently went out Air Rite took care of it. Arnie came out diagnosed the problem and had us back up and running in no time. Great doing business with a small family-owned business. Highly recommend!”

“Air Rite certainly did right by me! Our 20 year old HVAC system, which had been nursed along for the last few years, finally gave up the ghost. Arne came out and assessed the situation and recommended a reasonably priced replacement system. This morning he sent his team of Cameron, Daniel, David, and Keith, and they went to work. Before 3:00 p.m. on this wickedly hot day in the North County (105°+), they got our new furnace and air conditioning units installed, up, and running. Thank you, Air Rite!”

“We needed to have our AC unit serviced and called Air Rite. The woman who works in the office was attentive and kind. They were really busy because it has been so hot but she let us know the soonest they could send someone out. When the technician arrived he was kind and courteous. He went above and beyond to clean out the leaves that were in our unit and made it ready for summer. Thanks, Air Rite!”
