Extremely Impressed With Sal and His Staff
I called today to schedule a diagnostic look at my AC unit after checking Yelp and ChatGPT for recommendations. I was extremely impressed with Sal, the owner, and his staff’s quick response. He came out on the same day and was quickly able to resolve the issue, as his van is well stocked with supplies and parts. He was very friendly, yet professional, and reasonably priced. I highly recommend Cost Less for HVAC issues.
Betty Jean

Sal was excellent!
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!

He was an answer to my prayers.
I called today at 5:57 p.m. 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!
Julie Muonio
Solved the problem with our AC quickly
Quick to respond, available for a free estimate the next day. Both Sals (senior and junior) arrived on time (early actually), solved the problem with our AC quickly and effectively without pushing to replace the whole thing (as others have done), and added a couple of years (fingers crossed) to our aging system. Sal was very clear about our options and cost, and is easy to work with. Pretty sure I did not get the lowest cost to get the job done (never got details on the amount of refrigerant that was actually added/needed), but getting the system fixed quickly on a hot Sunday was totally worth it.
Onno Harms
Super Impressed!
Super impressed! The owner, Sal, replied right away on a 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 tank at a 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!
Yuting
I’m very satisfied and highly recommend CostLess Heating & Cooling.

He’s the real deal!
I can’t say enough great things about Sal! My air conditioner suddenly stopped working during a really hot day, and I was worried it would take hours—or even days—to get it fixed. But Sal came out right away and had it running again in a matter of minutes. He was incredibly professional, friendly, and clearly experienced. He explained the issue clearly, didn’t try to upsell me on anything I didn’t need, and made the entire process stress-free. I truly appreciate his honesty and fast service.

Sal came to the rescue
Today was a very hot day and Sal came to the rescue. I saw their advertisement for a free diagnostic on Google and my neighbor and I decided to give them a call right away. Sal showed up within 3 hours and fixed my AC really quick. Eventually, I am going to replace it because it is over 25 years old. My home now is cool and comfortable. Thanks a million.

They've got a customer for life now!
It had been a while since I turned on my a/c unit, so when I fired it up during this last heatwave, I got a bummer of a surprise. I called Costless based on their great Yelp reviews. Sal was able to quickly diagnose a blown capacitor and leak. He had the parts needed on his truck and got my a/c unit running in about 30 minutes! They've got a customer for life now! Highly recommend! 10/10! #savedtheday!
