 Trustindex verifies that the original source of the review is Google. A Plus was early with the appointment and I’m glad I called them. Michael had found issues with the A/C that others had not found.  This past Friday afternoon Michael had finished with the repair and determined that the A/C was now up to specs.  This weekend the A/C purred all weekend without a glitch and almost 100 degrees outside. The A/C can now maintain the programmed temperature without crashing and turning off. Thank you A Plus for fixing the unit right the first time.  I look forward to fall and setting up the winter tune up in September-October time frame

A Plus gets 5 stars and they did it right the first time

Very happy A Plus customer

 Trustindex verifies that the original source of the review is Google. I was so pleased with A Plus Heating & AC and the service provided by Zach yesterday!
Zach was very personable, professional and efficient in checking my furnace system. He gave me the confidence that the system was working properly for the season and identified and addressed all my concerns.
Thank you Zach and A Plus!
I will be using your company again in the spring for the AC checkup and will recommend you to friends and family!
A great local business!!

 Trustindex verifies that the original source of the review is Google. Zach was extremely thorough and showed great attention to detail. He took the time to explain everything I needed to know about properly caring for my furnace, including what I should and shouldn’t do to keep it running efficiently. I really appreciated his patience, knowledge, and willingness to educate me rather than just complete the job. His professionalism and quality of work were outstanding! I highly recommend Mitch and his team. A job very well done!
