"We were thankful for the efficiency at which the team was at determining the issue, providing and estimate, and scheduling our service. We had two workers on the day of the replacement who were punctual, courteous, and professional. Care was taken to keep our home from being damaged and the areas were cleaned prior to departure. Thank you for getting our new furnace installed before the external temperatures went into the single digits."

"DJ did a great job of explaining what needed to be done and how the work would proceed. We've lived in our home for 50 years and NEVER had the ducts cleaned! Got a coupon in a mailing and set up the appointment. The team arrived on time. k Rob & Andre were very professional and we're happy with the work they performed. Will definitely call them back in a couple years for the dryer vent (didn't know it was such a hazard). Have already noticed how much more efficiently our HVAC system works now that the gunk is gone."

"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.

"Our AC stopped working the day before Father's Day. Jeramy came out, not only on a Sunday, but Father's Day! He quickly realized out AC had a freon leak. He quickly fixed the leak and added freon. He was in and out in a very timely manner! He did not charge us for a service call, even though it was a weekend! We would definitely use Jeramy again and recommend him to anyone!"

"My experience with the Spengler Company was great.  Colby arrived at my house on time and then proceeded to perform the cleaning of my air conditioning unit.  He found that our refrigerant was low so he filled that up.  And he also changed our air filter for FREE!  He then gave me six options to replace the water heater in our home.  It was over 20 years old and had been leaking on the floor.  We selected the second option and he called it in and our water heater was changed out the same day!  WOW.  What service!  We couldn't be happier.
