Good Morning, Well our entire family have been using HSC Associates for over 20 years and they have always done a stellar job servicing and installing numerous HVAC systems in our various properties. Recently our Mitsubishi split went down in our main tv room during this lastest round of scorching heat. HSC responded immediately and between Marvin, Brandon, Kevin and Zack were able to find the problem and get it back into operation. Ahhhh! Cold air again!!! Great job fellas. 10 Stars for this fix. Thanks again. Loyal Customer, D. Barr Family
Employees very aggressive and rude make violent threats woukf not recommend their services.
Where to start, if I could I give 10 STARS!!! From first contact to end product in the team at HSC Associates Heating & AC impressed me. So let me give a very long story here for you to understand. A building was bought, had a old radiant floor system that was not properly installed I will add a photo of that mess. But since we had other plans for the money and the system kind of heated the building, so we were gonna make it work, and then it happened. The boiler went down, brought in a service company and they right off the bat said can't/ wont touch it.. huh, what! .. So it seems parts are far and few between for the band. So after a few calls found out Nobody would touch it. I was referred to HSC for an entirely new system folks let me tell you don't bother with other quotes nobody could come close to these guys! And when I say that I had many others come in and give me quotes, one place never even got back to me with a quote after they saw what was involved. So lets focus on HCS now and what they did. Salesman Marvin comes, great guy really knows his stuff. (mind you I have 30 years of building maint. behind me) We talked about what I like to see happen and what was needed for the Space we are creating. Next the Quote came and I was like no that cant be.. It was way lower then the others and very reasonable. Also they use only Lennox equipment and that alone is a great selling point!! The efficiency ratings are great too! So we get things set up to go. The hand off to George happens and again another great guy!! We explained our time table and needs and we were lucky enough for us, he was able to make it work. When the Crew shows up, Matt and his crew wasted no time, from bring the parts all in LOTS of Parts since we were going to move from boiler radiant heat to a HVAC system. The system if you are not sure what that involves is a Forced Air heating system, a Air conditioning system (coil on the heat system, and condenser out side and all the ducts, electrical, zones, dampers, control panel. Then they also tore out and removed the entire old system!! They worked so efficient that this big job took only 3.5 days and when I say days, these guys were on site before me and stayed later then me. So if you read this far and still here you should know by now I highly recommend HSC Associates Heating and AC for what ever your needs are!!! Huge thank you to the entire Staff!!
I've had a similar experience to some recent reviews. Over the years they put in two furnaces and central air. But my recent interaction with them by phone showed this is a different company now. I'm going with another company.
12/2025- Follow up: I did need a new furnace recently and I bought a Lennox 97% efficiency 2 stage gas furnace from another distributor/service company. If HSC was more customer focused and courteous, they would have received that purchase I made. I have been dealing with HSC for 15 years. I bought an A/C system from them and had them run new gas lines when needed and have been calling them for annual service for furnace and A/C. Today I called to ask about their billing for parts and labor for annual service that they did a couple of weeks ago. The person on the phone could not tell me how they bill. When I asked to speak to someone who could tell me, he hung up on me. When I called back he hung up on me again. When I called back again, the manager answered and gave me an argument for being disrespectful and cut me off as a customer. I never was treated so poorly for asking how a company bills for service. This isn't the same company that I worked with in the past. Their attitude is totally lacking in customer service. I have an old furnace that they have serviced well but when I replace it it won't be from HSC.
