Choosing the right Heating and Air Conditioning Contractor is very important. Chances are you are going to make a substantial investment in your new HVAC system with which ever contractor you choose. There is nothing worse than investing a large amount of your hard earned money in a new system and winding up with a system that is noisy, inefficient, and does not perform properly. Or even worse, one that fails prematurely. Surprisingly enough most HVAC Contractors have no formal training. Untrained HVAC Contractors frequently do not size systems properly which could result in improper cooling, very high utility bills, and even systems that fail prematurely. Before you even consider a contractor make sure they are NATE Certified and Air Balance Certified. North American Technician Excellence is the Prestigious Certification of HVAC Competence. Using a NATE certified contractor is like using a surgeon that graduated Harvard Medical School with honors.

"Just had a furnace tune up done at my residence. The young technician, Jesus Morales, showed up on time and he did a great job in performing the thorough inspection to ensure that the system was working properly. I want thank Southland Heating for their seasonal reminders and deals."

"Replaced my gas furnace and air conditioner with a heat pump. The only company I contacted who did a thorough analysis of my home and electrical system to determine exactly what I needed. Side note: I requested this service because my furnace quit working. The technician who came out to evaluate my home repaired the furnace for free while doing his analysis. I still bought the heat pump, but this company definitely did not simply try to just sell me one."

Please see our Special Offers and Promotions, for a limited time only! We service the San Gabriel valley. Owner Jeff Seale has been in the construction field since 1989. When he was starting out, he witnessed other contractors who were not focused on customer service. They either didn’t complete the work correctly or they charged customers for work that was unnecessary. Jeff believed that customers deserved service that was both dependable and professional. Accurate, born out of the need for committed excellence and communication. We pride ourselves on an outstanding record of quality service. Our experience is testament to the level of service and quality you'll get when you choose Accurate for your heating and air conditioning needs. We have a staff of highly talented and motivated individuals that are eager to help you with all of your needs. We are excited you have expressed an interest in our services!

We're not your average HVAC company. Our team brings vintage vibes with modern technology to keep LA comfortable, one home at a time. Started with just one van, a toolbox, and a mission to bring honest service back to the HVAC industry. Mike was tired of seeing customers get overcharged and underwhelmed by big companies. What began as a one-man operation has grown into a team of certified technicians serving the entire LA area. But we've never lost our core values ? straightforward pricing and quality workmanship. Our retro style isn't just for show. It represents our old-school approach to service combined with cutting-edge technology. We do things right the first time and keep LA cool when it heats up.

" ⭐️⭐️⭐️⭐️⭐️ I recently had HVAC Dudes install a brand-new central HVAC system in my home, and I couldn’t be happier with the entire experience. From the first meeting with the project manager, everything was clear, professional, and on point. He took the time to walk me through the process, answer every question, and give me a fair and honest quote. The installation team showed up on time, worked clean and fast, and the results speak for themselves — cool air flowing perfectly throughout the house. They treated my home with respect and left everything spotless. The entire process was smooth, efficient, and stress-free. If you’re looking for quality work, fair pricing, and a company that actually cares — HVAC Dudes is the way to go "
