S&L Prime A/C and Heating fixed my air conditioner the same day that I called. The technician, Phil, was thorough and fixed the issue quickly. He was also amazing with my two dogs! I would highly recommend this company!

We were looking to upgrade our HVAC system and got three quotes. S&L came recommended, so we had them come out and give us a quote. They provided three quote options, and were great at articulating the differences. They were also the only company that seemed versed on all the available rebates and tax incentives.

Installers came on time, were very polite and professional. They explained everything, and did a great job cleaning up.

I would 100% recommend this company!

We had a very positive experience with S&L Prime. I was 9 months pregnant and our AC system broke down in the middle of summer. S&L’s Mike and team prioritized us given the circumstances and moved extremely quickly to get us a new efficient heat pump system installed, including getting a crane scheduled that same week. The team was transparent and communicative, helped us obtain BGE credits for the heat pump, and were all around pleasant to work with. We were very happy with the service and would definitely recommend them.

Called at 8 am with a condenser not running. Fixed by 12:40 - not just a capacitor issue either. Very fair pricing!

Excellent service. Central AC stopped producing cold air. Mike explained what was wrong and fixed it within 5 to 10 min. Good price and great service. Will definitely use again and recommend.

Very satisfied customer. Mike was punctual, friendly and very knowledgeable about my a/c unit. I would call on S&L again.

I thought the cost for the service call was a little high, but I guess it's the sign of the times.

S&L came out quickly and was able to help with a fix with an older system that other companies had said wasn't possible. Cannot recommend them enough!

I've been using S&L Prime for years and have never had a bad experience. They just installed a new outdoor AC unit, furnace and coil. My AC died during a recent heat wave and they were at my house first thing after I called, immediately diagnosed the issue, provided recommended solutions, and scheduled my service.

The responsiveness at every stage was excellent. The pricing was competitive and fair, and the explanation of the job and my options was clear. Mike and Miguel arrived exactly on time, were extremely professional, and their work was immaculate.

Highly recommend S&L Prime for any service or support you need.

Dave was great and very informative to assist with our issue.
Did a good thorough check of our system to diagnose the issue as well as some educational advise. Keeping S&L in my contacts for all our system checkups and service.

We are appreciative that S & L had Michael C come out the next morning on Sunday to assess the issue with our air conditioning system not working. Thank you for the loan of two window units for us to get by while the replacement fan motor was on order. That was important for our three aging animals.

Mike did a great job diagnosing and solving our issue in under an hour. I can't recommend their service enough. Not only with the onsite visit, but over email they suggested solutions that I could do myself to avoid having the pay for a visit.

After solving our issue Mike also walked me through some basic maintenance I could do to ensure our system lasts for as long as possible.

Definitely give S&L a call for any HVAC issues.

S&L did a professional job on a mini split replacement. Mike and the guys were extremely friendly and knowledgeable from the get-go. They all had a fantastic sense of teamwork, and had a good time working together, which makes a BIG difference. Plus, they were so kind and fun with our 3 kids and pup...my sons had questions and they were happy to answer! Thank you so much guys--our family room is back to normal and feels great!

David E was fantastic. He was professional, affable, and knowledgable. Arrived on time, knew immediately from two questions where to start, diagnosed and fixed my 2nd /3rd floor ext. unit within an hour. He also made sure to check the vents and confirm the differential was what it should be at and the system was preforming to its capasity. Even wished me a happy weekend. I cannot recommend S&L Prime enough!

Everyone was so pleasant. Even my dog enjoyed the company. Since my purchase was a higher seer, I am noticing a more even cooling throughout the house. Thank you.

The technician was extremely helpful and knowledgeable, identified the problem quickly, unfortunately the problem is a faulty part that will need to be replaced. Great service, thank you.

I chose S&L Prime due to the great reviews here and I am glad we did. We had an A/C compressor issue a that a previous servicer (think color Blue.)quoted us $2,400 to repair! That company left us in sweltering heat for a day but Dave from S&L had our unit running in minutes for the price of a service call. We will definitely be using them in the future!
Update: We did use their service again and are very satisfied. Mike skillfully replaced the compressor motor.

Phil arrived on time and did a thorough inspection and cleaning of my Mitsubishi Mini Split. I asked him several questions regarding the remote and he did an excellent job of explaining how certain features worked. He was very patient with me as I was writing down the steps involved in getting the right settings. His knowledge of my unit was very impressive. Highly recommend!

Service within a few hours. Dave was great, professional, and quick. Our unit is on our roof. Two big companies refused to even evaluate the HVAC system, but Dave went right to the roof and fixed it. Highly recommend!

Incredible service!! Mike went above and beyond. He was helpful, fast, and so nice. He took the time to explain everything so I could understand it and answer all my questions. He even gave me tips on upkeep and cleaning. I am a customer for life.

From the moment I contacted them, their professionalism and responsiveness stood out. I called for an emergency service, and they were able to send a technician out that same morning. They were transparent about their pricing, and they were able to diagnosis the problem within 30 mins and had the part on hand. Great service all around. I will definitely be contacting S&L for any future Heating and Air issues and maintenance.

A technician was here within 2 hours of my call for service. Mike Miller was polite, professional and thorough. He explained everything he did and gave me a few pointers on AC maintenance. I was extremely pleased. S&L Prime has always provided me with excellent service.

Fast, efficient work/diagnosed the issue immediately, and the service didn't cost an arm & a leg. Great communication from the initial email/service request, as well as punctual. Highly recommend. Thanks for saving us from the heat wave!

Phil was on time, efficient, knowledgeable and we will sign up for annual checks to the system because of his findings. Diana was pleasant, efficient on the phone and even called us on Sunday to verify Monday morning appointment. Excellent service, thank you.

After loosing my air conditioning during three 100° days I placed a call for service. Initially I thought I would be waiting for service for a couple of days but the company kindly fit me in a day early and fixed my unit. Prompt friendly service and kept me informed on the time the service technician would be arriving. Love this company.

Tommy,Mike , Ken and Sean did a great job putting in a new air conditioning unit in my attic which registered 135! They were efficient, cleaned up spotless and were polite and friendly. I would highly recommend this company.

Mike came out after hours and confirmed the excessive heat may have locked out the compressor fan motor. Added a Hot Shot auxiliary capacitor.
He'll follow up tomorrow morning.

Outstanding service from beginning to end. Melissa in the office was terrific and Steve was great to work with on purchasing the unit. The install team of Tom, Mike and Brendan were simply outstanding. Very pleasant, polite, respectful and professional. The whole team did a great job. Don’t hesitate to use this company for your needs I think they’re the best!

The customer service rep who answered the phone was very cordial and nice. However, I would not use this company again. I haven't had my A/C unit services since 2018-2019 based on my previous experiences with companies trying to upsell units when I can't afford them. My previous A/C Tech passed away. So, I don't have someone I trust anymore. Last time he was here he filled my unit up with 4 lbs of R-22 Freon (this is a 30+ yr old unit). He told me to keep this sucker until he dies because, "They don't make systems to last anymore. They are designed for efficiency and not longevity".

Here is where I am a bit put off the most. The person on the phone said they could fill it at $200 a lb. When the tech came out he was told that he could only top it off it is was 1-2 lbs low. My system was 4 lbs low. He kept getting phone calls from the company which feels like there is some nonsense going on in the background to try and upsell me a new AC Unit maybe because I am a female. Don't know and I don't care, but I do work around ICS. I do understand how this stuff works in theory. I can also do basic math.

The tech (who was very nice...so I don't blame him) said, "Well, if this unit is leaking 5lbs a year, then I cannot legally fill the unit with R-22". I asked, "How much does this Unit hold". He informed me, "6 lbs". I said, "Well, as I've not had this serviced let's say since 2019 and it is now 2025, that would tell me it is not leaking out 5 lbs a year". I also said, "As I said to the rep on the phone and I will say to you now, I cannot afford to spend $7,000 - $12,000 on an A/C Unit right now." I literally cannot afford that right now and I just had to drop $4000 on a new Water Heater a month ago (which they didn't know and it is not their business).

He apologized and said that this is what he was told from the company and I can appreciate that. I am not mad at the messenger (technician). I told him I would be calling other Heating and A/C companies after he left (which I did). The next company I called made me a priority and came to my house 30 min later. The two tech's check everything and provided me with a list of solutions and costs to help me for now. They said I was 4 lbs low on the refrigerant and that there could be a leak based on it losing refrigerant over the last 6 yrs. However, it is very slight and they could fill it up. Note: Their cost for the R-22 was $150 a lb ($50 less than S&L). They recommended a Coil Cleaning ($200) and replaced a weak run capacitor.

Grant total with different AC company was Parts ($875), Labor ($50), and visit ($150) = $1075, This was $5,925 (if I got a $7000 AC unit) less than S&L. I still paid S&L the $160 visit fee, but worth it to realize I will NEVER use them going forward and I will NEVER recommend them based on their lack of integrity and honesty.

Again, not mad at the tech or person who answered the phone. Whomever was pushing this upsell is the problem. I would have told everyone to use you. I am very disappointed. The 2 stars I am giving you are for the kind Technician and lady who answered the phone only.

I had them change my 14 year old Trane Heat Pump with new Goodman Heat Pump, I regret why did I change the new system that had hell lot of issues since I installed than my 14 year old Trane. S&L prime sucks and their service is awful , multiple technicians came but still no one knows what’s wrong with the new system. I won’t recommend them to anyone.

Reason I didn’t call for past 1.5 years:

I’m hesitant to call your service team because none of your technicians knows how the Goodman communicating system works and they don’t know how to fix the problem.

Heater did not work last winter , I ended up using the portable heater across the whole house and now AC is not working.

Just had my HVAC system replaced. Everyone I’ve worked with has been responsive, punctual, and knowledgeable. I shopped between a handful of companies and landed on S&L because of their pricing and professionalism. Would highly recommend!

Service is great. But will say it would have been nice to see a small discount here or something. The same work was done within a week due to ants eating the part. Very odd. But I have put two systems in two homes using you guys. This seemed like a good spot to show a loyal customer appreciation. Not looking for freebie. But odd circumstances I get but less than 2 hours of work. I’m sure every other company would have done the same. So just sucks for us customers I guess.

it was just an assessment, but the person that came out was very knowledgeable and was able to explain a lot of things to me that have not been explained to me in the past

S&L is a superb HVAC company. Steve the owner came out last year during the Summer to give me an estimate on a new heat pump. At that time, he told me that my 12-yr old AC does not need to be replaced because it was still in an okay condition, but I was so impressed with Steve in terms of his honesty and how thorough he was in his assessment.

Fast forward to May 2025... my wife and I could not resist all the rebates and federal tax credits that were being offered at this time. I reached back out to Steve, and he quickly emailed me a new proposal and set me up with an installation date within just a few days of me reaching out. Steve answered my millions of questions with patience and never got frustrated or annoyed, like some of the other contractors would.

On the installation day, the crew was amazing, and they were very respectful of our property. Mike the manager had to come out a few more times to fix the wiring issues, but he was very professional and patient in dealing with all the issues.

I highly recommend this company for any of your HVAC needs.

Losing AC (blown compressor) during some of the hottest days of the year so far is traumatic. Fortunately... still in warranty. S&L Prime was the bright spot during the ordeal. The company was quick to respond and communicated very effectively throughout the whole process. They also displayed great care and concern providing us with a portable AC unit so we could have at least one livable area to occupy while we waited for a replacement. David, our technician who took the initial service call and installed the new compressor when it arrived was excellent! Kind, courteous and efficient. We are back in a comfortable space now. Thank you S&L and thank you David!

S&L Prime A/C did an excellent job installing my mini-split system and maintains it with great care. I would never use another company. Their technician Phill is so intelligent and thorough. I believe he can diagnose and fix any problem He provides good information, is honest, trustworthy and a super nice person.

I called S&L Prime at noon regarding a problem with my mother's A/C system. Within 40 minutes Mike, an S&L tech was there. He was friendly and professional. He immediately diagnosed the problem and had it fixed in an hour or so. Mike was knowledgable, competent and quick.
I will continue to recommend S&L Prime HVAC.

From the pre-sales estimate meeting to the final install,a very professional process and crew. We had 3 estimates, S&L was the most flexible and reasonable. Crew of 5 installed a multi room system in less than 2 days, No mess, no fuss, just get it done!! Highly recommended.
