Customer Testimonials

We have grown over the course of our 65-year history because of our dedicated employees and loyal customers. We are always grateful for the kind words of those who place their trust in us.


Prompt and professional . We had a particularly difficult plumbing problem. The job foreman came up with a different solution that 3 other plumbers had missed. This amounted to savings of 60% compared to fixing it the more common way. And on top of that they came in UNDER their estimate.


The proposal for a new HVAC system was by far the best price offered by other reputable companies. The installation was exceptional. All employees were knowledgeable, courteous, informative and friendly. Our new system is performing great as promised!


Great experience with Schlosser and Associates when our heater stopped working last winter. They came out in a timely manner and fixed it that same day. The technician was very knowledgeable and polite.
I would highly recommend this company for HVAC work or plumbing.


The servicing was great. You guys are real pros and I’m so glad I remembered you from years ago. You have a new client! I will not only be using you for A/C services going forward but likely for plumbing services too. My heater is under warranty for a few more years so I will still be using them for that until it expires but will likely then convert that for servicing to you as well. Anyway, it’s been a great servicing experience for me and I really appreciate the help from you and your talented staff.


I had a hot water heater installed, three valves replaced and an A/C tune-up. The staff at the office, as well as the technicians who came to our house for the work to be performed were friendly, knowledgeable and professional.


Thank you for all the great advice and service in getting my new A/C unit installed. Already recommended you to some friends down here in Middletown.


“Team Schlosser. Thank you for all the great advice and service in getting my new A/C unit installed. Already recommended you to some friends down here in Middletown.”


I had a HW Heater Installed, 3 Valves replaced and an A/C tuneup as well on March 20th. The staff at the office, John the service manager and Diamond as well as the technicians, Joe, Jason and John, who came to our house for the work to be performed were friendly, knowledgeable and professional.

Not only was the work completed in a timely manner, they also spent additional time at our house answering all the questions we had for them concerning the new equipment that we just had installed.

I will certainly recommend Schlosser & Associates to anyone that is looking for HVAC, Plumbing or home repair work services!

Excellent company for sure!

Recent major work on our hotel, in conjunction with our owners utility team, was excellent. The Schlosser team, led by Andy, were amazing and they replaced a key part of our utility supply with ZERO impact on our guests! Now that is SERVICE and SKILL, thanks from the Courtyard Newark at the University of Delaware!


The two gentlemen that came were friendly and knowledgeable. They were also very professional and made me feel like they knew their stuff. It didn’t take them that long but my sink is working and so is my dishwasher so I’m beyond ecstatic. I can see why they have been in business as long as they have.


They were friendly and professional. I was told they would be here between 10-12. They were prompt, they unclogged my kitchen drain and cleaned up after. They were great.


First class service at a budget price. We had to install a gas line for an outdoor electrical generator. Estimate was accurate, complete with information on the type of piping and how it would be installed. Service was prompt, people were friendly, and the finished product blended very nicely with our home. One of the rare few companies we’ll be contacting again for our next project.


Thank you for setting up the HVAC service for us. It was super speedy. Your crew brought the contract out last week when they performed the service. They did a wonderful job. Thanks again, and as always, for your quick and quality service. You do a great job.
