Recommended Customer Reviews

** WARNING! LIARS AND RIPOFF ARTISTS!**
The company I hired to install my wall heater was having problems with resolving some of the details of the correction notice. 3 failed rough inspections.
So off to YELP I went and found the twins so favorably regarded here. I gave them several calls before I got a human, and scheduled an estimate. Mr Harrison arrived 45 min late but did call to alert me after 35 min of waiting. My first impression when he drove up in his filthy, unkempt, company van with mismatched, bald tires and a cargo bed full of debris and tools piled one on top of the other was, ""Oh No!""
But then, thought I, YELP can't be wrong. Besides, who am I to judge a book by its cover. My own company car and desk are in disarray. So was Einstein's. It means nothing. (On the other hand, as it turned out, it meant everything and I deeply regret not going with my gut response.)
Mr Harrison--can't say which, after all their twins that go by the same name--quickly assessed the situation. He said ""I can take over the contract, make the necessary corrections today, or maybe Thursday latest, and call the inspector myself and meet him here to expedite the process say Friday.""
His price was $800.00. I was expecting something more in the range of $200-$300 total but then their goes those YELP reviews in my head again. Besides maybe there was more to it than I realized or was told by the inspector. A gas heater is serious business and I don't want to blow up because of carelessness or frugality.
Besides, a three day time frame was perfect for the sheet rocking that was almost complete. We could start the taping on Monday and seal up the gap in the wall and ceiling.
I wrote Mr Harrison a check for $400.00 and was looking forward to the great phone call I'd get that Friday afternoon. Unfortunately, the phone call never came. We had an opportunity to stop at the house Friday Night to check on his progress. Nothing had been done. No phone call with an explanation. When I tried to call him I learned the company had no receptionist, only two cell phones that the Harrison twins hadn't even had the consideration to set up with out going messages. After several calls and finally receiving a ""Sorry, this mail box is full,"" CLICK! I began to realize I wan't getting my moneys worth.
Finally that Saturday, I got a return call. I asked how the progress was going. Mr Harrison replied, ""Oh, I did pick up the parts, their in my van. I'll try to get the work done by Sunday; and, Monday, make the Inspection Appointment."" I replied, ""That's perfect. I'm having the water heater worked on and the Inspector can do the rough on that as well."" I was again elated and thanked Mr. Harrison. Again I asked him to give me a call when it was all taken care of. I had to work Monday and wouldn't be able to attend.
Monday came and went. By Tuesday the sheet rocking, taping, plastering and texturing have all been completed. The painters have started interior painting. The entire house is painted except the wall and the ceiling of the Wall Heater area. Wednesday I called the Harrison's. Mr Harrison now tells me, ""I've been waiting for you to call me. I'll have the work done tomorrow. You can schedule the Inspection anytime after that.""
""You were supposed to schedule the Inspection and be here to answer questions."" I said.
He replied, ""Schedule the inspection for Friday afternoon, I'll be in the area and will come by during the two hour window he gives you in the morning."" Another lie. On Friday morning, after several calls I'm told Mr. Harrison won't come to the inspection.
To top everything off the Heater fails again to pass Inspection. Mr. Harrison in his haste constructed a smaller insulation box out of less material than my original guy had and haphazardly placed it over his larger box leaving a gaping hole for flammable material to fall into. In addition, to access the clamp he was supposed to replace he cut the top metal reinforcement strap on the stud bay. An additional code violation. He later said, ""Oh, I had no choice but to cut the strap because I don't do drywall work""
Strange, the five drywall workers that were in the same room with him when he cut the strap stared in awe at his incompetence and wondered why he didn't ask them or call me to have someone trim the drywall for him. It was going to have to be trimmed anyway now to replace the strap. In hindsight, it just must have not been worth his time to do the job right.
Another week passes; with it, several more unreturned calls. Finally, after 3 weeks and a threat to seek someone else I get a response. I'm told, ""We don't come out when you want us to, we have to fit you in our schedule."" I said, ""Fine, but when you come bring a new strap."" He had the gall to say, ""I'm sorry, but that's not my field. If you want to buy the strap and leave it there I'll re install it for you."" I was in shock! The following morning I decided to fire him. Glad I did!

HIGHLY RECOMMENDED! 5 star service, beat everyone's price, and walked me through the whole process. The ""twins"" know more about furnaces, air ducts, and air flow systems than any professional I encountered (and I interviewed many!)
I had a huge, ugly, cold air return in my hallway that I wanted moved. Most professionals offered me expensive, poor, alternatives, but Supreme Indoor told me for a super low price I could just put it in the wall. Brilliant! I couldn't believe how affordable they were and talking to them was like listening to a ""How its Made"" episode on house heating systems.
These guys are fantastic listeners and make sure the customer is COMPLETELY satisfied with the service. They went above and beyond the call of duty (nights and weekends included!) and are a true gem. No need to shop around, seriously, these guys rule.

After getting 3 other estimates, Supreme had a mid-level estimate that I felt I could trust, along with their great Yelp reviews. Mr. Harrison and his brother very promptly replaced our old furnace with a high efficiency unit in a cramped crawl space area. They were able to finish it in 3 partial days and were very professional and friendly. The furnace works great and they were very knowledgeable and explained all the logistics of inspection.
We haven't passed inspection yet because they have to do some minor changes to drainage, so it's taking longer than I had hoped but I'm hoping to add to their review and support their commendable efforts!

Needed an old furnace inspected. Was informed that we simply needed the thermostat replaced. Wonderful service! Reasonable price...very honest. Would definitely recommend Supreme Indoor Climate Control!!

I highly recommend Supreme Indoor Climate Control! Our AC went out at 4 PM on a Saturday. I called Supreme at 5 PM and there arrived at 6 pm. They located the problem, made the repair, and left by 8 PM! Very courteous, reasonable charge.

Very quick response. They first tried to help me troubleshoot the problem with my AC over the phone, to potentially save the trip out (and cost). Once we determined a trip out was needed, they came that same day, found the problem quickly (in this case, a bad capacitor on the AC unit), and fixed it in ~30 minutes. Very pleasurable experience all around.

I called and scheduled an appointment for Mr. Harrison(s) to come and service my heater and clean my duct works.
They showed up on time and were quick to let me know that because my house was so old and the heating vents were constructed in such a way that their equipment couldn't clean my duct work. They told me were I could look to for help in this matter and went about servicing my heater.
They showed me pictures of a problem with my heat exchangers and ran test with equipment that showed that possibly CO2 was being pumped into my house when the heater was on due to the problem with my heat exchanger.
Even though the did the extra work, they stuck with their original price for the service and were nice enough to talk to my wife and I regarding our options and pricing if we wanted to replace either our furnace or the duct work or both.
If and when we decide to replace our furnace these two will be the first ones we contact

Mr. Harrison and his brother provided such great service. They respectfully informed us that our heater was not safe and leaking CO. They did not pressure us to purchase a new furnace from them, encouraged us to shop around and call PG&E for a free second opinion. They also went above and beyond by fabricating a holder for our filter so it maximize its effectiveness It is so nice to know that there are businesses out there like Supreme Indoor Climate Control.

I found Mr. Harrison on Yelp and my experience was excellent. It was consistent with all the other positive reviews.

All of the great reviews are justified. I called Mr. Harrison this morning because I thought my furnace had died, and it was really cold in the house. He was out within a few hours and determined that the pilot light wouldn't stay on because something was too dirty. He cleaned it off, and the heater started working again. I also learned that the furnace should be cleaned and serviced on a yearly basis. I will certainly do this because I don't want to have the cost of replacing the furnace. Mr. Harrison was professional, knowledgeable, and a nice guy. I have already put on my calendar to call Mr. Harrison in the fall to come out to do the service. I highly recommend him.
