The Guys in Action


"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!"

Kerri A

"By far one of the best heating and air-conditioning professional in Los Angeles . Great customer service, very knowledgable and very resourceful when it comes to practical and budget friendly solutions . I have worked with Tim a couple of times over the years and can highly recommend him ."

Ulrik N

"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."

Kelly G

"Tim is the best!!! He loves air conditioning and heating, he is quite passionate about it, and it shows......he did a fantastic job for me, installing central air and an air filtering system. He comes back for twice-annual service, and is always pleasant, trustworthy, honest and knows what he is doing. Can't recommend him enough. He was referred to me by my next door neighbors, who also rave about him."


"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!!!!"

Don G

"Tim Stivers is great. He came to my house and diagnosed the reason (a leak in the compressor line) why the AC refrigerant had been getting refilled every 3 months - something that my regular HVAC guy never seemed to find. If you are looking for the cheapest - go elsewhere. But if you want somebody who knows their stuff and....completes the job thoroughly and Tim."

Mark B

"Tim is always available and so helpful. I feel vey blessed to be able to count on him."

Anne B

"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!"


"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!"

Nathan M

"When my heater broke, I had

Tim out at the recommendation 

of a couple of neighbors. He was available for me the next day, even though he was obviously busy. True to my neighbor's words, Tim was AWESOME! He is super clean, super nice, and super intelligent! He LOVES what he does and if you ask, he'll tell you all about it. You just have to politely say "OK, Tim, I've gotta get back to my work now" if it's too much techy info. 

The cool thing was he actually wanted to let me know what was going on with my heater. I got up on the roof and took a look. He explained everything that was going on and why it needed to be fixed/replaced.

He is NOT "cheap" - you will pay for his services, but no more than what another heating/air person charges.

The best part: when he was on the roof and needed to go in/out - I just left the door unlocked. I trusted him that much.HIGHLY recommended, on the unfortunate event your heater or ac unit goes out."


"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."
