“Tim and his crew installed central heat and a/c in my house and we are thrilled with their work. They had to start from scratch and did a beautiful job. The whole crew was professional, polite, did a great job cleaning up each day. They were all so knowledgeable and perfectionists. Look no further, Tim and his crew are the best!”

“Highly Recommend! Tim was great. He handled an A/C call Downtown at my rental property. He was pleasant, honest and made the whole process painless. He e-mailed my invoice, dealt directly with the tenant and called me with updates! I love working with honest small business owners! We need more like you Tim!”

“I don’t understand the negative reviews here because I had a great experience with this firm. My air conditioning was out and i called Tim because he was recommended by our condo manager. He told me he could send someone out the next morning. The two men he sent couldn’t have been better. They were courteous, knew what they were doing, seemed to enjoy their job and, most important, kept me informed of what they were doing. They traced the problem to the transformer within the furnace/air conditioner that was burned out. They quickly went out to purchase another. But not only did they install the new transformer BUT they also installed a fuse that will turn off the transformer in case of overload instead of allowing the transformer to burn out again and possibly start a fire. I will not hesitate to call Tim and his team the next time I need an electrician.”

“Simply cannot say enough good things about Tim and his crew. He is excellent in every department– very respectful, always on time, great communication (he would email or call me back within minutes) very knowledgeable about air conditioning and very thorough in his explanation of all of our various options. He finished the job much sooner than promised and we couldn’t be happier with our new system. Just a really good, trustworthy guy with a solid crew.”

“Tim replaced my furnace a couple of years ago and did a tremendous job. I got his name and number from a friend of mine who had tim replace his entire heating and cooling system and my friend was thrilled with the job Tim did.

I cannot say enough positive things about Tim and would highly recommend him and his services!!!!”

"I have been using Tim Stivers for almost a decade in various homes. We met him when he serviced an entire building's worth of HVAC units in a Mills-Act historic core building in downtown, and since we moved out of the lofts we have used him in every single-residence home we've been in as well.

Tim is responsive, prompt, knowledgable, honest and well-priced. He is incredibly thorough and really knows his stuff when it comes to making recommendations for maintenance and fixing the often-faulty past work of others (which you find all too often when people are trying to flip/sell/rent homes and condos in Los Angeles these days!). Tim really cares about quality and making sure you have the best product possible in your home, including being sensitive to ventilation and clean air.

These days, it's really hard to find someone of his caliber, and i trust him implicitly. His crew is always polite and kind (he has trained them well!) and even after all these years you can see/hear him teaching his crew new things about AC units as they are doing inspections/fixes so that they can learn from his knowledge. He keeps a VERY tidy work area and always cleans up impeccably after any job.

Whether it's for a one-off inspection/check up on your AC units or for regular, ongoing maintenance in your home or in multiple-unit buildings, or even replacing an entire HVAC system (we've done all 3 types of jobs with him), Tim Stivers is the cream of the crop. I would highly recommend him to anyone who is looking to repair, service or just maintain your AC/HVAC units."

"We have used Tim 2-3 times now for our downtown loft heating/cooling system and have been very pleased each time. He and his team are very knowledgeable professional who thoroughly discuss repair requirements/options. I would recommend their services to anyone in need of a repair or check up :).

Thanks again for the great work.
Pleased Bartlett loft owners!"

"As a real estate agent I'm always looking for good people who get the job done correctly and on time. Tim and his team were referred to me by an HOA and they went above and beyond, even bringing in extra people to help us meet a deadline. They coordinated all the aspects of the repairs and sent incredibly thorough updates every step of the way. I will definitely use Tim again and can't recommend him and his guys highly enough."
