Thorough, Professional, and Honest
⭐️⭐️⭐️⭐️⭐️
Sal from Cost Less Heating & Cooling came out and checked my heater, AC, circulation, and vents. He was thorough, professional, and honest. After going through everything, he told me I didn’t need any repairs at all—and didn’t charge me a single dime.
That kind of integrity is rare these days. No upselling, no pressure, just straight honesty. I highly recommend Sal and Cost Less Heating & Cooling and will definitely call them again.

They are definitely our repair service for any future needs.

We're super happy that we asked CostLess to do the job.
Sal helped us install the Nest thermostat. Super efficient and knowledgeable!—2019
Now it's 2025, time to clean our HVAC system. It's been 6 years and we called CostLess again. Sal Junior was our guy and he did a great job. He set up equipment cleanly and orderly. He is super knowledgeable and explained to us the mechanism, the process, and what the maintenance includes. We were impressed. Sal Junior went above and beyond to check our exhaust fan and identified issues that's not even part of the HVAC. We're super happy that we asked CostLess to do the job. It's a good feeling when you see skillful workmanship and good work ethics runs in a family business. I'd recommend CostLess for their services.

Sal was a complete professional
Sal came out and diagnosed my system and quickly identified what was wrong. Unfortunately, it wasn't something that could be immediately repaired, but he walked me through my options and provided advice on how to best proceed given my current situation. He was happy to sit and talk about my concerns and was a complete professional. I have no doubt his work would be equal to or exceed his customer service skills. When I'm ready for a new HVAC unit, Costless will be who I will be hiring.
