Two years ago, the first and, until now, only review I ever wrote was to give Efficient Systems a glowing five-star testimonial. Since then, the head manager, Rob, has left. With his departure most of the talent left as well. I found this all out on my last, and I do mean last, maintenance visit. As part of the service plan I paid for, they come out once a year to service my water heater and HVAC unit. Although several upsetting things happened on this "routine" visit (the water heater flush forced me to go get my water tested because they implied my water softer might have broken <not true>, and they actually installed an outside light upside down. Swear to God. Upside down!), I think the following example illustrates best what kind of company they are now.
The air conditioner was working as intended when the very affable technician came over to service it. When he was done, the air conditioner just wouldn't stop. It got down to 54° inside before I had to turn it off all together. Hey, accidents happen. I wasn't worried. When they came back out to fix it, I was charged over $1,000. The new manager explained that "equipment breaks". He maintained vehemently that it was pure coincidence that everthing was fine before their visit and a freezing arctic afterwards.
Two years ago I wrote, "I use Efficient Systems because I don't know anything about plumbing or electrical work. I do know about customer service, and theirs is outstanding. In addition to their reasonable pricing, you won't find a company that cares more about keeping their customers happy." Sadly, those days are gone.

TL;DR Great value, providing relatively affordable access to superior solutions; courteous and knowledgeable technicians; peace of mind.I recently noticed that my conventional gas water heater was leaking. The previous owner told me it was eight years old, and I confirmed it was the tank itself, so I needed a replacement. Since I had some time, I got a couple of quotes. Full disclosure, I have an annual maintenance contract with Efficient Systems; I like knowing I can rely on them. Nevertheless, it is always a good idea to get more than one quote. I contacted a competitor whose number was waaay more for the exact same services and products.
So I felt really good about going with Efficient Systems pricewise. I had gotten quotes from both parties for a straight replacement and a tankless option. Given the advantages and the fact that the total cost for the tankless wasn't crazy expensive, I opted for the tankless.
This was a very involved installation, but the technicians handled it was aplomb. They were very communicative with our household and each other. The end result is a super clean, space saving, and efficient solution. It just screams professionalism. The unit is performing really well, and I have to say I never thought I'd be delighted by a water heater.
So, yeah, I have zero regrets, and let me tell you that is a rare thing these days. I have had, I think, six or seven people from Efficient Systems at my house, and to a man they've been consummate professionals. If you have tried hiring skilled and semi-skilled people in the last few years, I think you will appreciate what I am saying.

I have never had a more positive experience with any professional working on my home. Joshua and Sean were consummate professionals, and I feel confident in recommending Efficient Systems to anyone. My needs were very particular, and together they designed and executed a great solution at a fair price. -
