"Jimmy Gusky HVAC is truly as good as it gets. One of our AC units went down and through the warranty company found our way to Jimmy Gusky himself. Although out of their territory, Jimmy was willing to make the extra trip to diagnose the problem. He was very responsive to get our initial service call scheduled and determined the unit needed to be replaced, and we all know these units usually decide to break down only when pushed to the limit in the hottest summer months and we need AC the most. He did the legwork to get the warranty company to honor the recommendation and as you can see from the attached photo put in a much more substantial unit that is doing a fabulous job cooling the home. Add to that he actually had the unit and scheduled the install even before the warranty company approved the swap out. I that isn't one of the greatest examples of outstanding customer service and going above and beyond to exceed expectations, I don't know what is. Big thanks to Jimmy and team for their commitment to excellence!"

"We have depended on Fred and Son for expert plumbing help for years now. Today it was Joe who did the installation, and we couldn't be happier with his work. Equally important, we appreciate how friendly, considerate, and professional he was throughout his visit. We will continue to have Fred and Joe on speed dial!"

"Since I can do electrical and carpentry, I handled some of the work myself. GAC suggested what needed to be done, and reduced their price accordingly for the work I did. The rest was done professionally and effectively, and I have a good heating and cooling system now."

"Within 24 hours of my posting the need to replace my water heater the work was done - very efficient and easy!"

"Joseph Plumbing and Drain replaced our aging (21 year old) Rheem water heater with an AO Smith Proline 50 gal model. Kap, the owner of the firm, came out to give us an on-site estimate and a detailed explanation of the work to be performed. He showed up at 9:00 am two days later to do exactly what he had promised. Of the six different proposals that we reviewed, Joseph Plumbing and Drain came out on top. They were neither the lowest nor the highest bid, but in our view, the best bid. We found Kap’s price reasonable, his knowledge comprehensive and his work thoroughly professional. We felt we got a quality water heater and expert installation at a fair price."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"Mr. Brian Langford made all the arrangements with the installation of our gas hot water heater from Lowe's via McCarthy plumbing. He was extremely helpful,patient, professional and available to answer all questions. Due to his approach to his work, we will be working with both companies in the future. Only concern I have is the warranty between Lowe's and AO Smith Hot water heaters. Once the heater is installed, Lowe's severs ties. If there is a problem with the hot water heater, you cannot return it to Lowe's although it was purchased through them, this is clearly stated on the Hot water heater in bold writing."

"Brandon identified and isolated the water leak immediately. His expertise and speed were unmatched."

"Very Good! Arrived same day to assess project needs. Returned next day to install new water heater. Very satisfied with work ethics and clean-up. Would definitely hire again!"

"Services were prompt, clean and efficient. Tech was knowledgeable and personable. Water heater was affordable. Estimate (free) was done on site - not guessing over the phone."
