Usually I don’t write online reviews, but in this case, I will make an exception as the work of the 1-888-Heat-Pumps company was excellent. They installed a mini split heat pump in my older home in an upstairs bedroom. Andrei, as the Installer, answered all my questions taking great care in the placement of the indoor and outdoor units. The work crew, Drake and Jaxon, were on time, respectful, cleaned their work areas, and very efficient completing my project on the early side. I highly recommend them, have recommended them to a friend of mine, and intend to call on them again when I am ready to replace my gas furnace. I am pleased to write this review to help them grow their company.

Yellowjacket's team is terrific! The entire process, from initial visit through the final stages, was nothing less than excellent. Each and every person I interacted with was professional, extremely competent, knowledgeable, and friendly. My home is now warm & cozy, thanks to the mini splits, and I'm looking forward to using them to cool the house, too. Highly recommended!

Yellow Jacket did an excellent job in the installation of my minisplit heat pump. All the various personnel were competent and very easy to deal with. The installation work was efficient and precise. A couple things that stood out were the direct path they provided with regard to rebate info. (not so with another contractor I contacted) . And they also include surge protection for the electrical components on the outdoor unit--paying attention to all the details.

Can't speak highly enough about the team! We had a fantastic experience with them installing two ductless mini split units. The consultation was very thorough, with Andrei taking the time to answer our numerous questions and walk through the pros/cons of ducted vs ductless. Proposal was very competitively priced, clearly explained and included 1-888 handling multiple incentives on our behalf. Owen, Drake and Mike did a stellar install job, consulting us on all aesthetic decisions, showing up exactly on time every day and efficiently doing the work (no noise disruptions as we worked from home throughout the install). Post install, Andrei even helped us gather extra documentation to apply to an extra incentive we qualified for after full home electrification. Overall a joy to work with them and would highly recommend for your heat pump install!

They've installed two mini-split heat exchangers for us, and we couldn't be more pleased with their work. The team is friendly, knowledgeable, and efficient. They're sensitive to aesthetic considerations and more than willing to accommodate preferences. When they leave for the day, whether the job will continue the next day or not, they leave no trace behind. They communicate their schedule in advance, and they use tracking software that announces when they're on their way and shows their progress on a map. They know state laws and city codes. Additionally, they know what clean energy rebates are available, and they handle the paperwork required for them. Plus, they're very responsive to emails and texts. It's lovely to have a cozy house. We give them our highest recommendation.

1-888-Heat-Pumps did an excellent job installing my heat pump. The team was professional, efficient, and completed the job on time. The system works perfectly, and I’m already noticing improved comfort and energy savings. Highly recommend!
Teresa K.
Working with the entire team at Yellowjacket has been a joy. The team gave me the most competitive bid for installing a heat pump and has been super responsive to every need. Unlike most HVAC companies, this company has incorporated CMS technologies so I get confirmation of appointments, texts when they’re on the way, and thorough follow up. They are professional, competent, and a joy to work with.
Teresa C.
Andrei, Michael, and Brad were completely professional and easy to deal with. Mike and Brad were polite and considerate and very obliging--Mike re-set all my curtain brackets to make them match the one lowered for the mini-split. The units, both inside and out, were installed in a way that looked good and unobtrusive. All three, Andrei especially, were great at answering all my questions.
Barbara N.
Yellowjacket (now 1-888-Heat-Pumps) was excellent from start to finish on a job that was more challenging than anticipated. They were knowledgeable, friendly, thorough, very tidy, skilled, respectful and went to great lengths to make sure I was satisfied. I will not hesitate to recommend them.

In a single word: Attentive. The YJ team consistently made extra efforts to solve things thoughtfully, to make the execution cleaner, and to reassess a plan if/when our house presented its nuances. The crew is ideal—they kept us posted re: daily progress, cleaned up the job site every day, were pleasant and approachable. We replaced our gas furnaces with 6 mini splits, and the result is an even, comfortable temperature throughout our home. YJ is well-suited to the Berkeley area because they have both the expertise and desire to see each old/odd/charming/drafty house as a fun puzzle to sort out. Seamless experience, excellent investment.

QUESTIONS WE GET A LOT

Everything Homeowners Ask Before They Book

What does a heat pump install typically cost in the East Bay?

Every home is different — cost depends on the number of zones, equipment selected, ductwork, and panel requirements. During your free site visit we size the system to your home, walk through available incentives and financing options, and give you a clear written proposal with no surprises.

Most jobs are done in 1 to 3 days. A single-zone ductless takes a day. A full ducted swap with panel work can take three. We schedule around your life and clean up every night.

Yes. Our Fujitsu units are rated to heat efficiently down to 5°F. The East Bay’s coldest mornings rarely go below 35°F, so you’ll have significant headroom. Many customers say the heat is steadier than their old furnace.

Sometimes. About a third of the homes we visit need a panel upgrade or a subpanel. We assess this during the free estimate and quote it up front if required, then show whether any current incentives help offset that work.

Our own W-2 employees. Not subcontractors. The person who quotes your job is on the crew that installs it, which is why our labor guarantee is three years — we stand behind our own work.

Fujitsu covers equipment for 12 years. We cover labor for 3 years. Call us and we come back, no charge. The warranty transfers with the home if you sell.
