OneSource recently replaced my home’s HVAC system. The company’s Field Supervisor, Harry Wheeler provided the estimate - he did an excellent job explaining my options for a replacement HVAC system and was very patient in allowing me adequate time to ponder the options and explain technical terms that I didn’t understand. The guys who installed the system were clearly very hard workers, were respectful of both myself and my home. The new system is working well and I pleased with the estimate and installation process.
I had a wonderful experience with this company. They were very professional and dedicated to getting the job done! They installed a brand new A/C unit. The air felt so good that I had to wrap up in my blanket haha. Great job guys! 🎉
Had my first plumbing inspection, Dale was very nice, explained everything and made some excellent suggestions. Going to schedule my electrical next and then my Air Conditioner check. I definitely recommend this company and their yearly contract to get your twice a year heating and air checked, a plumbing and electrical inspection.
AJ, the technician, was wonderful! Sorry, I cant remember the lovely lady that answered the phone's name but she was wonderful too! Both were very imformative and so helpful. I didnt think anyone could come out the same day but they came out super quick and fixed the issue today! What a great and reliable company! I'd recommend them to anyone!
The guys at One Source did a great job installing my whole home generator. Harry and Roy were great with the quote and setting up the install day. There was one hiccup at the end of the installation, but they are working to get things resolved. I highly recommend them.
