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.

FAQs

Do you install Heat Pump Water Heaters?

Yes. We specialize in heat pump technology—both HVAC systems and water heaters. If you’re replacing a gas water heater alongside your furnace, we can bundle both installations and handle the rebate paperwork for each.

Yes! Heat pumps are highly energy-efficient and can save you money on both heating and cooling costs, especially when compared to traditional heating systems like furnaces and baseboard heaters.

Yes, we can help you with this!

With proper maintenance, heat pumps can last more than 15 years. Regular inspections and timely repairs can help prolong the lifespan of your heat pump, ensuring a comfortable home environment and optimal energy efficiency.

Heat pumps can work with most existing ductwork systems. However, it’s essential to have a professional assess your ductwork to ensure it’s in good condition and properly sized for optimal heat pump performance.

We can discuss options on this! It is possible to do it at the same time, here is our Contact Page.

We currently serve East Bay and South Bay in the SF Bay Area. 

Absolutely! We are happy to service both ducted and ductless jobs.

Ducted systems use hidden ducts to move air through vents in each room: great for whole-home comfort. Ductless systems, or mini-splits, use wall- or ceiling-mounted units to heat and cool specific areas. In short, ducted systems are centralized, while ductless systems give you room-by-room control.
