Signs You Need a New Air Conditioner in San Diego, CA
Your AC doesn’t need to fail completely to show it’s time for an upgrade. Subtle signs can reveal that your system is losing efficiency. Watch for these symptoms—it may be time to replace your unit with a modern, high-efficiency model.

Heat Busters Customer Stories
See What Our Clients Are Saying
We 100% recommend this company. We originally used them in the past to have our AC serviced and were impressed when there was no upsell to make any repairs to our AC system. We gave them a call when we wanted to replace our water heater and install a whole house water filter. The quote was extremely reasonable and within a week we had our new system up and running with a hybrid water heater, whole house water filter, and water softener system. Everything was put together very cleanly and tidy, and we are more than happy with the way it all turned out. Victor's recommendation gave us options and service that exceeded our expectations. Thank you Heat Busters, we'll definitely be repeat customers!!
Heat busters installed the Aquafer Water Source in my home. This was an excellent recommendation when I asked about my old water softener that had quit working a few years ago. This unit uses no electricity and filters to your whole home. Eliminates hard water scale, chlorine and a whole lot more things, making your dishes, laundry and bathing water much safer! I was very impressed how quick it was from the time I called them to when they installed it. Extremely reasonable labor costs. And they have also done maintenance service on our HVAC system! I will never go to any other company for HVAC or plumbing!
From the time I made my appointment threw Yelp the contact and response time was amazing! I was very impressed with their phone service. Victor and Aaron are very knowledgeable, pleasant, clean and efficient. I have mini split systems and it was really nice to see they were very familiar with them. I knew I was in good hands. Will continue to call Heat Busters for all my Cooling, heating, and water needs. Thanks guys!
I had a good experience with Heat Busters for relocating the condenser. Victor was very prompt in getting back to me, which I really appreciated. I hired him the same day that he gave the estimate. What stood out was his patience and willingness to offer valuable insights into my HVAC system. He clearly knows his stuff and resolved the issue quickly and effectively. The job was completed perfectly and without delay.
Heat Busters is an awesome company to work with. Victor is solid! Extremely knowledgeable, professional and Veteran friendly. I would not waste me time with any other company. My issue was resolved and I received an enormous amount of information concerning the nuances of my heating system. Great job Team!
Victor's awesome. We still have an AC unit that's original to our house and had a nightmare scenario where it stopped working on the 4th of July. He came out the next morning and got it back up and running. We had to call him back a few days later because the condensation was leaking, and he was able to come by the same day and seal up all the drain pipes and kept our old reliable central air unit going. Super honest and reliable, and we're going with Heat Busters for all HVAC stuff going forward.
Victor was very responsive and professional to work with. I reached out in the evening time on the weekend and he was available next day to troubleshoot our issue. He arrived right when he said he would, and immediately started working. I suspected our capacitor had given out and he confirmed that was true, and had a part available with him to replace it same day. Replacing the part and ensuring our AC worked properly afterwards was very quick. I highly recommend!
Thank you Heat Busters. Victor came out and was very professional. We went to find the condenser unit outside. He tested it, it was still running but very very old and outdated. So he said run it till it won't cool air and he will hook me up with the best deal possible on a more efficient system. Thanks buddy, your the man!!!
Very pleasant to work with from start to finish. We had a gable fan installed in our attic. They were on time and showed up exactly when they were suppose to. Victor istalled the fan in about 2 hours and helped us setup the mobile app. to control the fan's functionality. Throughout the process he was very honest, transparent and delivered exactly what he promised. The price was very fair and the quality of work was excellent. I highly recommend Heat Busters for your attic projects. You will not be disappointed.
Highly recommend Victor for his quality work. I had him out for maintenance/service on the mini-splits on my home, which many companies won't perform unless you're asking them to replace the system. Victor was reliable and explained the work to be done and what I could do on my own for service rather than pay a 3rd party. He even showed me what products to buy that he uses. Lastly, because I had done some of the maintenance work myself, Victor cut his service fee that was already agreed to. Will definitely use Heat Busters again.
Heat Busters installed a mini split in our home, and Aaron did an amazing job. From the initial consultation to the installation, everything was smooth and professional. He took the time to explain how the system works and made sure everything was set up perfectly. The installation was clean, and they left no mess behind. Our home is now so much more comfortable! Would absolutely use them again.
My outdoor heat pump stopped working in January and I'm so glad I gave heat busters a call. Victor was incredibly professional every step of the way. He explained both what was doing and why he was doing it. Fixing HVAC issues aint cheap, so the extra communication and professionalism was much appreciated. I'd highly recommend giving Heat Busters and Victor a call.

He was professional, knowledgeable. Fast service, fair pricing, and great customer care - I highly recommend them!
I am a single women over 60 and after getting 2 quotes from other companies, one that told me I needed an entire new system, Heat Busters was a relief. Victor and Aaron came in assessed the situation and gave honest feedback with options. The only ones that did not try to upsell me on something I did not need. Nice to find a company with integrity that did a fantastic job and at a great price. These guys are kind, honest and professional and I highly recommend them.
I am constantly looking to hire out some of the jobs I need done around my home. Finding a person you trust is difficult.
