Boris was very responsive and easy to work with from the start. During the bidding process, he replied quickly through Yelp messages and email, answered my questions, and was always very communicative. He came out quickly to assess the space and provide an estimate. His quote was the best price I received, and the turnaround time he offered was exactly what I needed. On installation day, his team arrived on time and was professional, detailed, and efficient. Most of the crew worked outside on the installation, and they actually finished faster than promised. The work was very clean and carefully done, including all drilling, line routing, and placement of the units. Boris made sure to explain each unit and how everything works. He turned on every system and confirmed they were all working properly before the team left. They also cleaned up thoroughly, and there was no mess or trace of the installation left behind. Really great experience overall. I would definitely recommend Covac and Boris for a ductless mini-split installation. read more

On time and kept contact. 1 hour 15 min install for one room one zone. 9k BTU. I got circuit breaker just in case. If you have 20amp dedicated line no need but I got just in case. When finished he did quick demo and install was pretty clean. He got down in science. read more

They were so fantastic! Prices were great. They worked so quickly and cleanly. Units are cooling great!

I've dealt with Boris. He's been really responsive and installed 4 units in my 3 bedroom home in one day. Air conditioning is wonderful in my almost 100 year old Spanish style home. Reasonable pricing and great follow up 2 years later. They came to me highly recommended and I recommend them going forward. read more

Covac Ductless Mini-Split Air Conditioning - Mini-split - Heating & Air Conditioning/HVAC Near Me - Alhambra, California

If you are like me and have not repaired a split air conditioner then I would totally recommend this place. The response was quick and when Boris came to service my AC he was professional, friendly and did not make me feel intimidated. He diagnosed the system and told me what was wrong and fixed and tested the unit. If I have any future problems with any split AC units, this is the place I will call. read more

Highly recommended. Do NOT go with those morons who will charge $50,000 for your house! Boris charges a little over $3000 per unit. We had an excellent experience from the planning to the execution to the payment. Boris is a kind, pleasant professional who works with an older person and a younger person in his crew. Clearly he knows what he is doing, because he has his own company manufacturing the mini-splits. Each mini-split has its own outside compressor box, so you can add more later - they don't all run from the same box. They will work with you in scheduling and placement and such, and they are polite and EFFICIENT. I had to teach a class on Zoom and Boris waited patiently to ask me questions. The price is very fair as well, and when my bank annoyingly only let me send over 1000 dollars per day, Boris was unflappable and did not mind that we paid that way. The machines work beautifully to dispense cold or warm air as needed. My 1927 house finally has some AC! read more

We recently got two mini splits in our home and it is a game changer! I can't imagine having to endure the summer heat without them. I'm so grateful to have found Covac! As a new homeowner, finding trustworthy people to work on your home is hard. Boris was not only extremely knowledgeable, he is as reliable, honest, hardworking and trustworthy as it gets. He was incredibly respectful of our home and left everything neat and clean. He was very efficient with his time and answered all of our questions with patience and kindness. I highly recommend him to anyone looking for quality work. All around, I was truly impressed with the quality of their services, the professionalism, and the kindness of Boris. The cherry on top is that you're supporting a family owned business! read more

Had a line out of my home fail. Father and son came over and fixed it tout de suite. Son checked the inside while dad finished up outside. Quick and reasonable. Still working fine. read more

I WISH I COULD GIVE BORIS 800 stars!!!!! But yelp only lets me give 5 but just know that if 800 stars was an option on this yelp app I would give all of them to boris!!!! He was simply the best. The sweetest young handsome man. He was so polite and he even took his shoes off when walking through my house cause I'm Asian and he knows the rules of an Asian house. He's smart too. The install was professional, quick, clean, efficient, and most of all cost effective. I called him in the middle of a heat wave and he came in three seconds and installed everything in five seconds. My house is so cold. It's like a igloo in Antarctica and I can see my breath when I breathe cause it's so cold in here man I love it in here. It's so cold. I'm never gonna leave. Thank you Boris. You're the best. I'm gonna install seven more mini splits just so you can be in my house again thank you so much! read more

They installed a mini-split at my elderly parents' home. This company is professional and efficient, and their work comes at a fair price. Highly recommend! read more

Another five star review for Boris! What a truly nice guy. I wanted to add a mini split to my garage which we are converting into an office and reached out to several other companies for quotes. I usually got a runaround before finally getting a number, which was usually about twice the amount that Boris has posted directly on his website. How much do I love this price transparency? The price is the price, no runaround. I was a bit worried that his prices were so much lower than the other quotes that we were getting, but so many 5 stars reviews on yelp intrigued me. I decided to research Covac a bit more - the mini split units that they install are manufactured by Covac (no middle man or brand name mark up) and Boris (at least in my case) installs it himself (with a helper). A smart business idea if you ask me. Boris inquired as to the dimensions of my space and we decided on the 12,000 BTU. This was Wednesday and he had an opening for Sunday so I scheduled it. On Sunday, he texted to let me know he'd be arriving closer to the end of my two hour window, then texted again when on the way. When he arrived, we looked at the space together and he gave me suggestions for placement both inside and out, then got to work. It took maybe an hour and looks and works great. Boris gave me a tutorial about the unit and how to use it. Why can't every home upgrade project be this easy? Huge fan. read more

We received a prompt quote 3 months ago. However, we didn't get the work done because we wanted to see how our central air would work... our house has a bit of a warm spot. Well, we decided we need to supplement our AC. I contacted Boris again, and he scheduled the appt two days out. He arrived 1 minute before the 1 hour arrival window. The install was done very professionally and cleanly... Not to mention Boris was pleasant to interact with! I highly recommend this company. And their price really is hard to beat (based on another quote from another 5 star company). I'll update this review if the unit somehow fails to perform. I'll also post photos that'll show the new look for the 24,000 BTU unit. Thanks Boris!! read more

I called and got a response right away. I wasn't very aware about mini splits but I spoke with the best man in the business, Boris, and his professionalism and knowledge were top notch! Installation for my family member at Alhambra was super smooth, safe, and hassle-free. He explained to me every step of the way and made sure I was comfortable with the device. Plus, the Warranty is super exceptional! Happy to support local and help each other during the pandemic. Don't let Covid stop you from getting Covac! read more

We bought a mini split from Covac back in early 2022 for my mother-in-law's place, and it's worked great. When mom-in-law asked about paying for a routine checkup, the folks from Covac very honestly pointed out that technician servicing wasn't necessary unless something was wrong. Thanks for the great product and the honest interactions! read more

We have a bedroom in our house that get really cold in the winter months. So we decided to get a slit mini ac/heater installed in the room. It's very quiet and efficient.My niece used Covac and she was pleased with their work. I called them and they responded right away. They are dependable and honest. Within a few days I had the unit installed and it works so well. Best decision we ever made to call Covac. I highly recommend this company. Get in touch with Boris. He will help you with your questions. Super knowledgeable and easy to work with! read more

Covac Ductless Mini-Split Air Conditioning - Picture of split mini unit - Heating & Air Conditioning/HVAC Near Me - Alhambra, California

We decided to finally treat ourselves to some climate control, since we have been mostly working from home. So glad we hired Covac to put a mini split in our garage office! We got it Installed just in time for a heat wave, which would have prevented us from being able to work. The unit itself has nice features and is so quiet! I had to actually ask my husband if it was on. Night and day from the window unit we had previously! It kept our poorly insulated office at 70 even in 100 degree heat. Boris sent a very detailed quote. He was able to do the install about a week out. He and his team (3 total) came out right on time, and in masks. He discussed our placement options for the inside and outside condenser, and they got to work. About 1.5 hrs later we had a nice cool office! I wish all contractors were this easy to work with! read more

We recently got a mini split ac and couldn't be happier going with Covac. Boris was quick to respond to our inquiry and was able to squeeze us in sooner due to a last minute cancellation. They were on time and finished installing everything in less than an hour. read more

Recently bought our second mini split unit from them. Got the first one in 2017 and we have never had any issues. The unit and installation costs are competitive and reasonable.

Covac Ductless Mini-Split Air Conditioning - 9,000 BTU mini split unit installed in master bedroom. - Heating & Air Conditioning/HVAC Near Me - Alhambra, California

I iJust had 2 upstairs bedroom units installed. I'm very happy. Great installation should have done this years ago! Thanks Boris!

Worth the investment! My parents have an older home with outdated insulation, and the original 9k BTU Boris installed didn't cool the room effectively due to the abundant sunlight. After upgrading to the 12k BTU, it works much better for our needs. I'm impressed with the attention Boris gave to my concerns, and I appreciate that this is a family business. I've already recommended him to my sister and several neighbors. read more

Cannot say enough good stuff about this place. I made the mistake of investing in a ductless mini split before that broke and no one would service it. Second time, i used covac... it runs great and boris comes back to service it if need be. The pricing is also great read more

Excellent experience, all around! Boris and his team are true professionals. I had a horrible experience with another company a few years ago and was left with a lemon AC system in our detached office that never worked reliably. We budgeted to replace the entire system and decided to go with CoVac, and I'm so happy we did (and that we decided to move forward with safety precautions in place due to COVID-19). The first thing that really set CoVac apart was excellent communication. Super clear and prompt email and text communication from start to finish, all questions answered and all details provided. Installation was also excellent, very prompt, fast, thorough, and safe - Boris and his team wore face masks throughout and sanitized the space before leaving. Finally, I just wanted to mention the attention to detail - I was surprised when I came back to my office after installation and saw that Boris had taken the time to mount the remote and dock right next to my light switch, because he saw I had the old system remote there. To me, this is true customer service - going the extra mile, even on something small, makes such a difference. Thank you, Boris and the CoVac team!! read more

Boris answered all my questions, the pricing is pretty simple, super fair price with a complete breakdown of costs. I had them install 3 units in my Los Feliz Duplex, very professional , in and out leaving zero mess behind. I will use them again if the need arrises! read more

After getting estimates, Boris from Covac was the lowest for mini split a/c. He is very knowledgeable and by asking me information about the sizes of the rooms where I want to put a/c, he was able to give me pricing in writing. He was very upfront with the cost and everything was itemized. He was able to schedule the job in about 2 weeks and was in my house on the exact time that he told me. When he got to my house, he explained and let me decide the best place to install with his guidance. He finished the job in about 5 hours. He explained how to use the remote which he mounted conveniently on the walls. I'm very happy with his work and will use him again to put a unit in my small guest house in the back in the future. I highly recommend him if you need ductless mini split a/c done. PS: He also took off his shoes when he's in the house which I really appreciate!! read more

Absolutely satisfied with the product and service. Probably the best value for mini splits out there. Love that they were upfront about all costs in the beginning so there weren't any surprises. They were on time and completed the installation of one unit in about 2 hours. In and out. Everything works as describe! read more

I can't say enough good things about my experience with Covac. From my initial point of contact with Boris to completion it has been a professional and pleasant experience. Boris gave me all of my options and pricing upfront. He was quick to respond and transparent about the costs in a way that no other company did. Other companies responded with a "we will see but it's roughly...." Their pricing, work ethic, and communication is great, and now I have an awesome quiet and cool mini split for my living room. They did such a great job I'm having one installed for my mother next week. If you are on the fence with who to choose look no further! read more

I've recommended Boris and his company many times and I'm looking forward to the next opportunity when the need arises. He provides a great alternative to central AC/heat and those who have availed of his work have been very pleased with his work. Keep it up Boris and Thank you! read more

I can't believe I have suffered a lifetime of sweltering Alhambra summers without A/C in my house. Getting central air in our 104 year old home would not only be very expensive, but also a massive project. (We have a finished attic so there isn't a way to vent the air throughout the house.) Friends had recommended I get a mini-split, but the BTU's were identical to my portable AC (which does not cool our house whatsoever) so I wrote it off as a waste of money. When my BFF got her mini-split from Covac, I was shocked at what a difference it made in the temperature of her home. I got a quote from Covac and called 5 other companies for comparison. Not only was Covac much cheaper than their competition, but their service was A+ and our mini split works very well. For the 1st summer in my life, my house is FRIGID and my family and I are comfortable indoors! I don't understand why mini-splits work so much better than portable ACs (even though the BTUs are the same), but they do. We haven't gotten our 1st power bill post-installation but our portable AC raised our bill $400/month (and the unit was LOUD) and I expect our bill to be much more reasonable with the mini-split. (My BFFs power bill only went up $100/mo and she had 3 units installed in her home.) I highly recommend Covac for all your AC needs! read more

Amazing! I called and they came out the next day! Installation was quick, easy, and our new mini-split works GREAT! The unit itself is so quiet!!! I am so incredibly pleased, thank you so much! read more
