“S & L Air Conditioning and Heating has great all around service. Had a problem with my heating unit and called in early this morning and got greeted with great customer service by Jay. He processed my service call today and was able to come out and fix my unit a few hours later. Jay and his crew were very nice and made recommendations about my unit and services I need done in the future. I really appreciated their top of the line service and will be calling them the next time I need service.”

"S & L Air Conditioned and Heating installed my new Nest in my home. My HVAC is very old. According to Nest their thermostat couldn’t be installed on my unit. I called S & L just to double check because Washington Gas was offering such a good deal. Sure enough they worked their magic and installed my Nest. I recommend S & L very highly for all your HVAC needs. They are extremely professional and friendly. Give them a call and you will be pleased with their service and reasonable pricing.
