Called the afternoon of Dec 23. Brenda on the phone was super-friendly and scheduled a service call for the next day. Sure enough, the technician got here at 1:00pm on Christmas Eve. Got everything working again for $80.00. Could easily have told me it was a $500 repair and I'd have believed him. Go with Mannix, you'll be glad you did!

DON'T LOOK ANYWHERE ELSE! This is your company to use! Our 30 year system failed, we got multiple quotes and settled on Mannix, as Eric best understood our environment and what we needed to correct. He worked closely with us, matching our needs and budget with the technology. Boy are we glad for Eric. Matt & Marcellino are TOP NOTCH TECHS! We could hardly tell they were here, until the AC started ...

The Technicians arrived on time and completed the work in less than one hour. They were courteous, professional and very efficient. They removed any mess and left the area clean. They also demonstrated how the new humidifier will work in the colder weather. We are looking forward to more air comfort this coming Winter.

I called Mannix after my 25 years old ac system gave up. Then ERIC HOLZWORTH showed up, explained to me everything, the options including the price comes with it. However, he wasn’t trying to push me to get the top tiers. He laid out on the table whether it is worth to get the top tiers, the second or the standard one based on my situation. And I like that. After getting some quotes from others, I...

OUTSTANDING CUSTOMER SERVICE I submitted a request for an estimate online and the owner Jerry Mannix, responded almost immediately with a recommendation that will save me over $6,000, compared to other estimates. In addition, we talked the next day on the phone, and NOT ONCE did he attempt to up-sell me on products or services that I didn't need. Highly recommended. I definitely will use them in t...

They responded quickly in the negotiation phase. On the installation day in late June 2019, I found the new furnace (Carrier 58TNOA110C21–20) was different from what I ordered (58CVA110-20). I was told the one that I ordered was discontinued. The new one is basically the same as the one that I ordered. In early July, I noticed, while I was in the basement, there was loud noise from the furnace/blo...

I have been using Mannix for a couple of years to provide routine maintenance for my HVAC system. Last year they replaced my hot water heater and last week they replaced my furnace and air conditioning units. Throughout my association with them their technicians are punctual, knowledgeable, honest, considerate and pleasant. The office staff are also very accommodating and nice to deal with. 'Based...

When I started looking for quotes to replace my water heater, outdoor A/C unit, and interior air handler, Mannix was able to send a representative the day I called. Jerry Mannix, the owner, came himself to measure my space and provide a quote. New models of interior air handlers of the type I needed were smaller than my existing unit, meaning that drywall repair would be necessary afterward. Jerry...
