Serving Alameda, Contra Costa, Marin Counties and Beyond!

I have been a part of the HVAC industry for 14 years now and I have seen a lot through the years. I have to say that Mike and Tim Hassler have been amazing, encouraging, supportive, appreciative and honest.

During my tenure here they have shown me in their decisions and actions, that they are 110% committed to customer satisfaction. They do and coach the team to do what’s in the best interest of the client.

They have shown genuine compassion for their team-members. Whether they are top management or an entry level position, the employee’s wellbeing is ALWAYS taken into consideration. They show great concern for every team member and their future. They offer ongoing training and they invest in their people.

Hassler Heating and Air Conditioning has a bright future ahead. Mike and Tim make the journey of growth and challenge enjoyable. They are just down right great people to work for- I enjoy being a Manager and part of the team!

I have been with Hassler Heating for over four years now, and loved every minute! Since I started working here, I have watched the company grow exponentially while I grew personally and professionally as well. I started as a CSR and have risen and grown to Assistant Service Manager. There is always opportunity for growth and advancement at Hassler. The HVAC business is a fast-paced, challenging, ever-changing environment which has taught me how to not only think on my feet, but also critically. Working for Mike and Tim Hassler has been a wonderful and rewarding experience. It’s not every day you find a company with owners who truly care about their employees. They have gone above and beyond to insure every employee is taken care of. With wonderful benefits and ongoing training, they insure their employees are happy, healthy, and educated in their position. I’ve also never met owners who were so customer focused and dedicated to customer service and satisfaction. Hassler Heating is hands down the best company I’ve work for.

My name is Rahsaan Whitney. I have been an employee here at Hassler Heating and Air Conditioning for about 3 ½ months. I came over from another home performance company that closed their doors and ended residential service.

I have had nothing but good experiences ever since I came over. The office staff at Hassler Heating and Air Conditioning is top notch. They really care about their employees. I love that all I have to do is ask to get something I need to make my job more efficient. Be it a personal cell phone to a specific tool request, my needs are always taken care of. This is a big change from my former employer. They were always trying to save money at the cost of doing the job right and keeping their employees happy.
The medical, dental, and eye benefits are a big plus. I honestly feel they care about my wellbeing. Keeping your guys healthy and safe is a big part of employee morale.
I feel like I am a part of something here. When it comes to suggesting a company to do excellent quality work for my friends and family, I am very confident about recommending Hassler Heating and Air Conditioning.
I hope to be a big part of this company in the future. This is an awesome place to work!

Best Regards,
Rahsaan Whitney
