I called three places and left messages. Matt called me back pretty quickly for a Sunday evening and said he could stop by today before 12 and that he would give me a call 30 minutes prior. I got his call at 11:15 and he was there at 11:45. I have an old 3.5 ton compressor which is not new. Fearing the worst, I was concerned about leaving my wife home to deal with it. Usually, I get 3 phone calls after the typical man-splaining to my wife about why we need to spend thousands. My wife called me at 12:30 and I was bracing for it. To my surprise, she said that Matt was done and it was only a small part which needed replacement. Thanks for your honesty and responsiveness even though we're not a service customer. We will definitely call you for the big job when the time comes.

We wanted ivory instead of white, so Alexis was wonderful & helped us order what we liked best. The guys were prompt, courteous and efficient. They are EXTREMELY neat too!

I highly recommend this company all around- the employees are great.

6/2026 UPDATE: After writing my original review a couple of…read moreyears as the time service was excellent and timely, it has drastically gone way down. I called their office 5 times from December 2024 until early the following year to get a proposal for a mini split, never received a return call to either schedule an appointment or provide a proposal as they know my house well. Miscommunication with a contract which took several months to correct when billing an additional amount. However, during the spring service call the billing had not yet been fixed and the technician Angel was instructed to remove my water ordered for my whole house filtration system without telling me. I only discovered it when Angel as to access the boiler room. (This same technician left my hallway walls dirty after I had just had them painted. Fortunately, I was able to clean them.) I knew no servicing was to be done until Winter so I asked why which he responded he was taking the filters that belonged to GMG. I advised that I ordered them and they belonged to me with an adjusted invoice only for the filters and not install. When I had the winter service performed in November 2025, I addressed the duplicity with Joe and the lack of a quote for a mini split. He stated that Andrew was bad at communicating and would share my concerns. I waited to hear from Andrew, nothing so I reached out. An appointment was scheduled and the understanding that the contract would be amended one time only to include the service for water filtration unit which had not been done under the previous contract. No revised contract received and appointment not kept. Since November, I reached repeatedly via text, voicemail and email to receive the corrected contract and then to schedule the spring service, NO RESPONSE! I'm attaching screenshots of the text messages and emails. I then asked to provide me the type of filters so I can get another company to do the work, STILL NO ANSWER with no attempt to address the matter. IT'S A TOTAL LACK OF PROFESSIONALISM; JUST CHILDISH BEHAVIOR! On top of all this, I receive on a regular basis emails to provide a review on a link to them only, not on Google. Well you got your review to your company directly and not on Google. I NO LONGER RECOMMEND THIS COMPANY!!!!

Contacted DLC and spoke with Darnell…read more Darnell was responsive and communicated to me clearly that he would stop by (property is tenant occupied) to diagnosis and recommend a corrective action. He did just that and was able to arrange the repair date with the tenant (without my additional input) - this saved me time and effort! Darnell's rate is highly competitive for the area and returns a great value for his quality of work. Darnell sent me an electronic invoice as well as a hard copy - and was able to take CC over the phone. This made things a breeze! DLC Heating and Cooling is now my go-to outfit for heating and cooling needs for my rental property in Mastic Beach! I highly recommend Darnell and DLC to anyone needing prompt and honest service!!!
