Hempel Air Conditioning

After 2 weeks on waiting on my techs who installed my AC to fix my AC. They gave up and told me I had to buy another AC unit. 5−10k. I decided to get a 2^nd opinion. This was during the 2015 heat wave and everybody was busy. Voicemail greetings greeted me a we book for the next 2 weeks message. So I finally dialed Steve with Hempel. He came out the very next day and was able to fix my AC within the hr! Turns out my knuckle head techs installed the motor the wrong way. Steve charged me $ 500 for a new motor, labor included.
I’ve also recently used Hempel for my office too. Steve sent his son the next day and we received the same consistently great service too.

Same issue as Anon had (review below) Hempel came out 3 times and my central air unit has gone down 4 times.
Last fix was done by son. He showed up took a look and said «I forgot my tools» I’ll have to come back tomorrow.” Son never apologized for the inconvenience and didn’t seem to want to be there or do the job. My instincts wanted not to go with the job but did any ways and my central air is down again. (Freon leaking from unit)
Steve installed a condensate pump in my attic 2013 and it went down this summer of 2015. I found a pinched line that was pinched by a zip tie. It leaked down into my ceiling.
1^st job — freon leaking — not fixed.
2^nd job — replaced condensation pump — broke year and a half down the line.
3 rd job — freon leaking — not fixed

We met Steve about a year ago when our air conditioner seemed to be running out of steam. We found him based on the Unilocal reviews because most of the other air conditioning repair people we had used left us feeling like they didn’t know what they were doing or were intentionally ripping us off. When Steve left, we were so impressed, that we knew that we would hire him to install our new air conditioning unit when we were ready. Fast forward to this year… He came back and gave us a very reasonable price to install our new air conditioning and duct work. Both he and his son were on time, reliable, and charged us exactly what they said they would. We couldn’t be happier and our house is now freezing cold — just the way we like it! I can’t speak highly enough of them.

Had another ac issue on my 25 year old Lennox ac that no one else can repair of course in the middle of a 100 degree heat wave. Steve came by the next day and repaired it and even put me a new filter on my heater at no charge. Grateful I didn’t have to pay another $ 6k for a new ac! Come on ac you can make it another year! :)

I live in Walnut and chose Steve and his son, Jason, to assess our 40yo dead A/​C on the merit of Unilocal reviews.
They showed up on time, worked with us on costs, weren’t greedy at all and recommended getting a new 4-​ton replacement unit. We scheduled installation for the following week. They were on time and took no longer than the estimated half-​day for everything. They do great work, explain everything, and were pleasant and engaging. I highly recommend this company.

Always a good investment with this father & son team. They’re so nice and friendly and on time too. Call backs are quick. Nothing negative at all. Been my go to people for 7 – 8 years now.

Steve is as good as it gets, he came out to fix our AC a few weeks ago due to a bad wire and it was not getting a good enough current to the capacitor to get the compressor started. he changed the wires and cleaned the contacts, rewired everything, and he also changed out our air filter and check the freon levels, made sure everything is working as it should. he also advised me that our AC/​heating unit is a 22 year old model its working fine, but if anything craps out (he observed our compressor is making a weird pitch) it will have to be replaced altogether, and will be costly. but he said he will do his best to see what can be done to keep the unit running until we are ready to change it out.
fast forward to this past weekend, our AC is starting to blow out warm air again i gave hm a call to see when he has time to come check our unit again, he came over at the promised time and earlier, found that it was the same issue, and did the whole repair, changed to a thicker gauge wire and made a new contact to see if it will fix the issue and he did it under warranty and did not charge us a single dime. he did advise that if this happens again he will have to try to route in a transistor or a split wire to try to help prevent the wire from being burnt out again. again, if your around this area,
you have any AC/​Heating issues you got to give this guy a call. his prices are more than fair and he is heck of a cool guy.

Steve and his son (I believe) stopped by a couple months ago and looked at our condo heating system. In about 5 minutes, they told me why we were not getting any heat… Previously, we had another HVAC person come out who told us we had to change the unit. But with Steve, he told us that we just had to make a connection to one of the pipes. It was that simple. After calling the plumber to connect the pipe, we now have heat again.

Great service. Was in a real bind — my mother-​n-​law called late in the evening and had heater trouble — the fan would not turn off even though the thermostat showed that everything should be off. I was out of town and could not help her out. Did get her to turn the unit off through the breaker box. I found Hempel from reviews on Unilocal.She contact Hempel and they scheduled an appointment and showed up on time. They did their diag and found the problem and more importantly showed her the shorted control board. Really appreciated their promptness and honesty. Highly recommend Hempel.

I am surprised by the overall rating for this guy. My AC was not turning on consistently. He came and changed a bunch of parts and it worked while he was there. He charged 3X for the parts and even shamelessly said that he charges that much for parts. After a few months, same problem. he came back and changed a few more parts. Again charged an arm and a leg. Still the same problem. On top of this, he said I don’t need to buy another furnace, though I told him my furnace was 15 years old. Of course he doesn’t want me to buy a new one. This way, he can keep screwing me.

I called Hempel based on the great reviews on Unilocal.This is one of the reasons why Unilocal is the most useful thing on the internet. Without Unilocal reviews, you risk getting flakes and phonies especially when it comes to home and A/​C repairs. I know since we had to put in over $ 20,000 worth of repairs into my home after a disastrous stint with a horrible tenant over the course a year.
I called Hempel and they were very nice over the phone and accommodated my 9 – 5 working schedule. Steve stopped by on a Saturday morning when we were having the 100+ daily temperature heat wave. I do appreciate him coming over on a weekend in the busiest season for AC repairs. He found the issue right away. The tenant has yanked out the water hose and broke the reservoir that collected the excessive water. I had several Chinese handy man doing patch up jobs that supposedly would fix the issue to no avail.
They ordered the part for me and it took a couple of weeks. They once again accommodated me and came install it over a Saturday. Even though the price was a bit steep at $ 600. I got a fully functioning AC now and not have to worry about water all over the garage.

Steve answered the call and was quick and have us a schedule.
He came on time and quoted less than estimate. Charged us fair price and uses local good quality parts. He did the job in a timely manner and explained things clearly and is very knowledgable

Our AC went out on one of the hottest days of the year. After reading the reviews on Unilocal we called Steve and he responded immediately. He installed a new unit in a couple of hours at a very reasonable cost. The work was first class, friendly, and met all of our expectations. Without reservation we recommend Steve (and his son) for any AC job.
Thanks Steve!

Highly recommended! I called Hempel because of all the positive reviews. Sure enough, Steve delivered. He arrived on time, diagnosed the problem and replaced a blown fuse and bad capacitor on the AC unit. He also added additional freon. During the whole time, he was very cordial and took time out to educate me a little about AC.
And to top it off, he charged me a very reasonable price. I would definitely use him again.

I am not going to parrott all the positive comments here but will say take all the positives below and that’s what I experienced. VERY nice guys, very honest, and fair priced. My AC was old and very time consuming to get into yet these guys did and I still have my arms and legs. I HIGHLY Recommend these guys and will call again when needed.

I had called Steve a few months ago in order to try to diagnose and repair my AC unit due to a low temperature split, and his immediate diagnosis was that due to a AC compressor issue it would be best to replace the whole outside unit for ~$ 2600 ($ 1900+700 parts). As I’ve already researched the typical cost, I was not stunned by the figure.
I eventually got my Home Warranty to cover the repair, but only after taking 4 months of constant repairs because they kept misdiagnosing the issue (#1 Added freon — leaked out, #2 Flushout my lines, nope, #3 replaced the compressor pump — all the coolant leaked out a month later, #4 Finally replaced my whole condensor assembly with a new unit — Voila!). While I still saved money with my Home Warranty, Steve got the diagnosis correct the first time around.
I called him again a few months later for my Parents AC unit which was not working right. A Costco HVAC guy had came by a while earlier and said we needed a whole new system for $ 12,000. Steve said it just needed a hard-​start capacitor with the HVAC. So for $ 150 (parts included), he repaired my parents AC unit and other than a simple blown fuse, its been working great since!
I’d highly recommend him.

Steve was very prompt at getting back to me and was very easy to get an appointment catering to our schedule. The diagnostic/​initial visit fee was fair. It counts towards the repair if anything is found. Fortunately for our case no major issue was causing our system to fail and he resolved it very very quickly.
Why I gave Hempel Air such a high rating is that in addition to a quick fix Steve made my money worthwhile by inspecting the other components of my HVAC, educating me on how my system works, and tips on maintenance and prevention measures to keep it running when he could have took off to his next appointment.
This is a testament to Hempel Air’s professionalism and emphasis on customer service.

Look no further! These guys are the real deal. As with everybody else, I found them through Unilocal.
I have around a 11 year old unit that recently went out. Steve confirmed again with me in the morning for our appointment at 2 pm and his son Jason arrived early at 1:50 pm. He was able to diagnose the problem within 10 minutes or so and explained every step of the way. Halfway through, he suggested we add more freon because he said it was low and wasn’t cooling as much as it could be. We measured the temperature before adding the freon and after. Sure enough, he was right and the temperature dropped at least another 8 – 10 degrees.
He worked the entire time he was here and explained as best he could what needed to be changed and why.
I got an entire fan motor replaced for $ 385, and 1.5lb for $ 40.
He also changed 2 of my filters free of charge.
Absolutely recommend to anyone who is looking to get their A/​C serviced.
Thanks again Jason!

Thanks to Unilocal I found Steve and Hempel Air Conditioning. I noticed his great reviews, gave him a call and left a voicemail. He called back later that afternoon and we set up an appointment for him to be at my house within a 2 hour window on the following day and he showed up as scheduled.
My AC unit is 28 years old and in the past, AC repairmen have always tried to sell me on a new unit, but that was not the case with Steve. He’s obviously been doing this for a while and immediately recognized my unit, asked me a couple questions, and in a matter of minutes he diagnosed the problem — a blown transformer that shorted out due to some bare wires at the outside unit. He had the part in his truck and fixed everything on the spot. While he was at it, he topped off the freon in my system. His bill was pretty much what I it would have cost just to have my AC unit serviced.
Great to find a skilled, honest, and reliable businessman like Steve. I recommend him highly.

My wife and I have been living in a cold house for the past month because the repair guy we hired to fix our heater just vanished after indicating he was waiting for the part to come in. And this guy came as a recommendation from a family member. What a joke. So we decided to fire him and search for a new repair guy through Unilocal.Hempel Air Conditioning was the first place that showed up when we searched in the Walnut area. We thought we’d give him a try. After all, we needed to have the heater fixed ASAP since it’s now going to rain for the next week.
I never got to meet Steve, as my wife was the one home at the time, but from what she told me, this guy sounds very knowledgeable and fixed the problem quickly. And the price was very reasonable. He didn’t even have to order the part; he just went to a warehouse and found what he needed to get the job done. It’s good to know we have a reliable heating/​air conditioning person near our house. We’ll definitely use him again in the future and would highly recommend him to others. We’re finally warm and toasty in our house.
