What Your Neighbors Are Saying About Us

We just had the pleasure of having a new HVAC system installed by Arturo and Mark with Thompson’s. I could not be happier with the entire process from quote to finish. The results looked better than I expected which is always great! The team was very considerate, respectful and made sure to keep it a very clean job. I can’t wait to finally be comfortable this summer. Our home never had an A/C unit. I got multiple quotes and Thompson’s design made the most sense and the pricing was fair. I highly recommend this company and crew.

Ignacio is super friendly and knowledgeable. He troubleshooted and fixed my kitchen faucet and whole house water filter issues pretty quickly. Thank you! Second review, we went back with Thompson Plumbing again because the first time was great. Ignacio came back out and quickly detected a plumbing leak which was actually creating a lot of water damage in our garage ceiling. He fixed it quickly so we could get the restoration guys in the next day. Quick, efficient and professional work with a friendly face. I definitely recommend.

Ignacio and his team were friendly and took care of the problem with expediency. I had minimal time to have an auxiliary water heater removed to facilitate a roof replacement. The removal and rerouting of pipes was performed quickly and set us up to upgrade the main water heater when there is time to do so Thank you. i will definitely use him and the Thompson team again to address future plumbing needs.

Ty did a great job on the repair of my furnace. He explained what caused the issue and what was required to fix it. I signed up for the annual maintenance program because I had such a great experience with Ty and Thompson Plumbing & Heating. Ty came back again and was extremely patient with me in his explanation of why the thermostats were operating as they were. I would definitely recommend Ty and Thompson Plumbing and Heating to anyone needing repairs on their furnace.

We had our A/C installed, our vents/ducting updated and our furnace replaced by this company, and the experience was excellent from start to finish. They were punctual, professional, and very easy to work with. One thing we really appreciated was receiving a text beforehand with the technician’s photo and profile—it made us feel comfortable and prepared. The entire team was friendly and knowledgeable. We also purchased their maintenance plan, which helped us identify other areas that needed attention. Thank you, Thompson Team!

Signs You Need Immediate Emergency AC Repair

Some AC issues can be scheduled for a routine visit, but others call for urgent attention. The longer specific problems go unaddressed, the more damage they can cause to your system and your home. Call us right away if you notice any of the following:

Your AC is running but not producing cold air, leaving your home warm and uncomfortable, no matter how low you set the thermostat.
The system keeps cycling on and off in short bursts, never reaching the desired temperature.
You hear strange noises from the unit, such as clanking, grinding, or shrieking that were not there before.
There is a burning smell or signs of electrical trouble near the indoor or outdoor unit.
Your home feels far more humid than usual, even given Oceanside’s naturally coastal air.
The system has stopped turning on altogether despite the thermostat being set correctly and the breaker appearing normal.

When something feels off, trust your instincts and give us a call. Catching problems early saves time, money, and comfort.

Common Causes of Sudden AC Breakdowns

An AC breakdown that feels sudden is usually the result of something that has been developing over time. In Oceanside, the coastal environment adds an extra layer of stress on home cooling systems. Salt air and persistent humidity can corrode outdoor unit components, degrade electrical connections, and reduce system efficiency more quickly than in drier inland climates. Refrigerant leaks are one of the most common causes of sudden cooling loss, as even a small leak can leave a system unable to do its job. Compressor or capacitor failure can shut a system down without much warning. Dirty evaporator or condenser coils, or clogged air filters, force the unit to work harder than it was designed to, often leading to overheating and an automatic shutdown. Faulty wiring, worn contactors, and tripped breakers round out the list of usual suspects. Routine maintenance is the best defense against these issues, but when a breakdown happens anyway, our team is ready to find the problem and fix it fast.

Our Rapid Emergency AC Repair Process

Getting your home cool again starts the moment you pick up the phone. When you call Thompson Plumbing Heating and Air Conditioning, a knowledgeable team member will answer, ask about your system and the symptoms you are experiencing, and dispatch a technician to your home as quickly as possible.

Your technician will arrive on time and conduct a thorough diagnostic to identify the root cause of the failure, rather than just addressing surface-level symptoms. We explain what we find in straightforward terms and present your repair options clearly before starting any work. Because our trucks are fully stocked with a wide range of parts and tools, the majority of emergency repairs are completed in a single visit. We do not consider the job finished until your system is running correctly and you are satisfied with the results.

After-Hours and Weekend AC Repair Services

AC systems have a habit of breaking down at the least convenient times, and we plan for that. Thompson Plumbing Heating and Air Conditioning is available for after-hours, weekend, and holiday repair calls because home comfort emergencies do not stick to a regular business schedule. Oceanside evenings can stay warm well into the night during summer, and a sleepless night without air conditioning is something no family should have to deal with. Whether your system fails on a Saturday night or a holiday afternoon, you have a dependable local team ready to respond.

Emergency AC Repair FAQs

How soon can a technician reach my home for an emergency AC repair?

We work to dispatch a technician the same day you call, and many emergency appointments are fulfilled within a few hours of the initial call, depending on your location and time of day.

Do you charge extra for emergency or after-hours AC repair calls?

After-hours and emergency service may include an additional fee, but we always provide transparent pricing upfront before any work begins so you know exactly what to expect.

Is it safe to run my AC if it is making strange noises or blowing warm air?

It is best to turn the system off until a technician can inspect it. Running a failing system can cause additional damage and may turn a straightforward repair into a more costly one.

How does Oceanside's salt air affect my air conditioning system?

Salt air accelerates corrosion on metal components, particularly on outdoor units. Over time, this can affect performance and reliability, which is why regular maintenance is especially valuable for homeowners near the coast.

What brands and types of AC systems do you service?

Our technicians are trained to work on all major brands and system configurations, including central air conditioning systems, ductless mini-splits, and heat pumps.
