"Very pleased with our new air conditioner installation. The salesman was very nice and explained everything to my satisfaction. The installers were efficient and knowledgeable as well. They showed up exactly on time and were finished earlier than I expected. Work areas were cleaned up, inside and out. Not even any metal shavings in the grass where the new ducting was cut. One of the nice gentlemen even explained the new thermostat they installed. I highly recommend Southport Home Services."

"Harker Heating And Cooling is the best HVAC contractor we have ever worked with in 40 years. Their web site proudly says they are an “honest company with Midwestern values.” That is absolutely true. Their representative provided in-depth advice, answered our questions. and returned our messages. Their techs were knowledgeable, professional, careful, and friendly. They were on time, on call, and on budget. The service they provided for us over the years could not be better. So when the time finally came to replace our old furnace and A/C we selected them. Unfortunately, they encountered many unexpected problems installing our new equipment. Many more than they had anticipated for the job. But their representative pledged to address every one of them no matter how hard it was for them or how much of their time it took. And that is exactly what they did. No quibbling and no questions. They got the job done right. If you want an honest family contractor who stands behind what they do, and lives by those Midwestern values, then this is the company to hire. You will be glad you did. Doug and Margie King Mount Horeb, Wisconsin"

"Called them as A/C was not working. They came out and refreshed freon. that was $215 fee. Our A/C was old and we were advised that it may or may not last. We decided to get a new A/C as ours was 20 years old. They advised me of the different models that they work with and gave me a written estimate and let me choose. The.y also subtracted the cost of the freon from the installation cost of a new A/C. One thing that was very impressive was that they were very punctual and gave us estimated time to have work completed. We ran into many other vendors who could not seem to provide accurate information. My wife and I felt an immediate concern for our worries from Oscar. We felt our needs were met and was very happy with service provided. I appreciated the way we were treated. This is a small business that seems to go the extra mile for you."

"I have been very pleased with all the services that Master's has done for me. They installed a new sump pump, water heater, furnace- air conditioner, kitchen faucet-drain, water softener, and installed new shower plumping(faucet and drains). I join their Membership Club and have been very pleased with the inspections and maintainace of all my equipment. They also did a great job cleaning my ducts. They show up on time, are professional and thorough, they always clean up very well when done. So I plan on having a long relationship with them."

"We found everything and everyone to be very efficient and pleasant. There was one glitch, however, when the electrician didn't turn on the fuprnace before he left Everyone was very apologetic and things were rectified very quickly. Also, there was a loud banging noise when the furnace turned off. This also was rectified very quickly. The serviceman was very apologetic"

"Awesome! We have never felt more comfortable and satisfied hiring a contractor! Brian came out within a day or two to look over the project, and then within another few days had a written quote! This was a huge project, and they handled it like no one else could. We interviewed 3 other companies and hands down, chose Arctic Air. Within a weeks time, they had removed 2- 250 gallon oil tanks, filled with oil mind you, took out the old oil furnace, replaced with a new gas furnace, and installed air conditioning! Not an easy task on a 125 year old home! Will definitely recommend to everyone!"

"Jim is local. It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job. He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer, Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.
