Jeff Orellana and his team , David Mares and Daniel Avila spent a full day at our home, doing maintenance for all of our heating and air conditioning. They noticed an area of increased carbon monoxide and did a full investigation and recommendation for repair/replacement of our bedroom furnace unit. At all times the men were professional, and courteous. They explained all of the issues and recommendations sufficiently for us to make an informed decision as to how to proceed. We recommend them highly.

Ivan was great. He was very nice, pleasant and made sure everything was working before he left.

1700684337

I scheduled a service call for a client’s forced air heating unit with Brody Pennel Heating & A/C. My day started on a good note when service techs, Benny and Kevin, arrived on time for the scheduled 8 am appointment. In addition to being prompt, they were knowledgeable and skilled professionals who assessed, explained, and corrected the problems my client was experiencing. As a Realtor, its important for me to have knowledge of reliable trade contractors I can rely on and refer to my clients to meet their needs. Based on my experience today with Benny and Kevin, I will definitely consider Brody Pennel Heating & A/C in the future.

We’ve worked with Brody Pennell for years and they always do a thorough job. David Mares came out and and was super conscientious with his inspection of our furnace, showing us pictures and videos so we clearly understood the condition and the issues we should be aware of. Then Ken Shannon discussed options and alternatives. He was informative and never pushy. We use their maintenance inspection plan for heating and air conditioning to give us peace of mind and it’s been worth it. Highly recommend.

Thank you Daniel and Brody Penney for your continued service.Nov 18 2023 Armando came by to do a touch up on the thermostat and went above and beyond with explaining exactly how a heating system actually works and why it needs to be replaced every 10-15 years.
