I really appreciate his honesty and attention to detail. I highly recommend Costless Heating & Cooling and will definitely call them again for any future HVAC needs.”

We called Cost Less with a concern about our A/C and furnace units right before a heatwave. On super short notice Sal was able to send out his team and upgrade both units at a very reasonable and competitive price. Sal and his team were very knowledgeable, respectful and worked in a timely fashion. Would highly recommend!

Sal and his team are very professional and honest team. They delivered on what the promised. Also, didn’t have to go through stipid negotiation on price.

I had a great experience with Costless Heating & Cooling Inc. They came out to repair my air conditioner and did an amazing job. The technician was on time, professional, and explained everything clearly. The repair was done quickly, and my AC is now working perfectly.

What stood out to me was how honest and straightforward the service was—no pressure, no upselling, just quality work at a fair price. It’s not easy to find companies that truly care about their customers, but Costless definitely does.

I highly recommend them to anyone in the San Jose/Bay Area who needs HVAC service. I’ll definitely call them again in the future!

I’m so grateful for Costless Heating and Cooling! My AC stopped working and they came out today (on a Saturday!) to fix it. Sal, the owner, was professional, friendly, and worked quickly to get everything running again. You can tell he really cares about his customers and goes the extra mile. Highly recommend Sal and his team for anyone needing fast, reliable service!

What I am going to address here is why you should consider to contact this company and use their services. Sal, the owner, replied to my messages in no time, promptly called me and explained everything I like to know. No pushing. I have requested bids from four companies to replace our old, broken AC condenser and fire furnace. After I carefully examined and compared all proposals, Sal's came out with the best configuration and cost, meet my budget.
About his crew. Members are with great skills and attitude, very pleasant to work with. Good communications when performing the installation. We have few "problems" uncovered during the work, Sal and his crew explained to me in details with solutions, to my surprise, Sal expressed there is no additional cost to me. This totally eased my mind. They finished the job in one day as promised.
You have every right to find vendors to do the job for your HVAC needs, but never leave Cost Less Heating & Cooling out.

Sal's experience and knowledge of the AC systems are the best in the business. I appreciate his honesty and his caring for his customer. Highly recommend anyone who needs their AC system serviced or inspected. Expensive, but I think it's worth it.

I had a great experience with SAL. He was professional, knowledgeable, and very efficient. He quickly diagnosed the issue with our AC and had it fixed in immediately. He also explained everything clearly and gave helpful tips for maintenance. I really appreciate his work and would highly recommend him to anyone needing AC service!

I called today at 5:57 pm to Sal and he texted me back in seconds and asked how he could help. I told him I’m fighting cancer and my AC has been out and the heat is bothering me . He came right over and fixed it for a fair price. He was so very kind and professional. He cared enough to help someone. All of the other numbers we called were booked out for weeks. I would definitely recommend Sal and his company to everyone. He was an answer to my prayers. Just a really nice guy!! Thank you Sal!

We recently had our air conditioning repaired, and the service was outstanding! Sal was professional, friendly, and clearly very knowledgeable.

Perfect service! Sal is the best in town!! Highly recommend him! He came to repair the AC in my house. We've used them in the prior house as well.

Super impressed! The owner Sal replied right away on late Friday night when our AC stopped working and came out early on a Saturday morning. He figured out the problem in minutes and had my AC cooling again in about 20 minutes by swapping out the capacitor, recharged the 20-year old R-22 tan with reasonable price and suggested adding a hard start kit to save electricity and help the compressor last longer. Quick, friendly, and really knows his stuff. Highly recommend!

Highly recommend! Sal was quickly able to troubleshoot and fix the issue. He knew very well about the HVAC and electrical system related with it.

Sal was excellent! His initial response was quick, and he was able to come the same day. He was communicative, punctual, and very easy to talk with.

Upon arrival, he quickly diagnosed the problem and resolved it at a fair price. For perspective, another HVAC company had come just a day earlier and quoted me nearly 20 times what Sal charged.

I highly recommend his work—professional, honest, and efficient.

Thanks again, Sal!
