Report
We were referred to Brennan's by family and we're not disappointed. Aaron Sajeski came out to service our neglected system. He was very knowledgeable, recommended course of action but was not pushy and gave additional advice and insights to help maintain our systems. The coils had been neglected prior to us moving in and looked like cardboard inside the unit. Once he was done the system looked brand new and the house is already cooler including our upstairs which never seemed to cool correctly. Would highly recommend Brennan's and if given choice on technician would request Aaron for any of our HVAC needs.

I've been using Brennan's for years and I'm so glad for the team and service. Aaron recently serviced our HVAC system and he was great. On time, professional and helpful. Highly recommend Brennan's and Aaron for service and for system installation! Service: HVAC system maintenance

We have been with Brennan's for well over a decade and would not consider any other HVAC provider. Their technicians, such as Aaron, are thoroughly competent, professional, and courteous. You feel as if they are serving their own family. Brennan's has performed major systems replacement and ongoing routine maintenance for us - all have been excellent.

Brandon from Brennan's was great. He arrived right on time to assess our 16 year old Carrier AC system. After identifying the issue, he laid out a variety of options for how to best address the problem. He didn't pressure us into making any particular decision and patiently answered all of our questions. We contacted him later that day after we made our decision and he quickly got our appointment scheduled. Would recommended.

Report
Our A/C decided to stop working on the first super hot day we needed it to. Called Brennan's and they sent a tech out same day which would already earn a 5 star for responsiveness. The tech quickly diagnosed and found out our outdoor unit quit working because the capacitor just failed. He had the piece in the truck and replaced it right then. Cost of part was $160 and labor (diagnostic fee otherwise) was $96.
Last year we called somebody else and diagnosis was less, but again it could just be last year's prices. We like Brennan's much better though. The rep on the phone was nice. The tech was thorough, kind to inform us of different things, and didn't try to sell a full replacement of our unit while ours is still in a very good condition. Would give a double 5 star if I could.

This morning May 21 I woke to have my house 82 degrees and climbing. My air was not working after reviewing several companies I called Brennan. The person on the phone told me tech could come today but the cast of service call is double time. I agreed, the tech would arrive around noon. Brandon arrived shortly after 12 I gave him the history, he stared checking things and explain to me his diagnosis.
The capacitor. There expensive! Brandon had one one his truck replaced the old one and now I have air. I did buy a maintenance agreement everyone should. This cost me 3 times as much not having a maintenance agreement and they would have caught this before I started my air conditioner. I have asthma and the heat and pollen would have sent me to the hospital. Thank you Brandon! He was professional, and explain things to me and offered future assistant with a maintenance contract I believe Brennan looks out for the best interest of there customers!

They responded quickly and professionally. The tech showed up on time and did the work needed quickly and efficiently. Very polite and kind. The prices were fair and well communicated. Will definitely be my go-to for HVAC repair!
