About
Maksbuilder is Orange County's heat pump and high-efficiency HVAC specialist. Our factory-trained install crew handles every project, and I personally — as the licensed contractor (CSLB #1095368) — do every estimate and inspect every install. You meet me first, you get a real engineering review of your system, and the work doesn't leave us until I've signed off on it.
Every system we install gets a real Manual J load calculation, properly sized line sets, and start-up commissioning. That's the difference between an HVAC system that runs for 8 years and one that runs for 20+.
Services:
• Heat pump installation and replacement
• Ductless mini-split installation
• High-efficiency AC and furnace replacement
• 24/7 emergency HVAC repair
• Indoor air quality testing and improvements
• Maintenance plans
Brands: Daikin, Goodman, Lennox, Carrier, Mitsubishi, and many others
Service area: Lake Forest, Mission Viejo, Irvine, Aliso Viejo, Laguna Niguel, Laguna Hills, Ladera Ranch, Foothill Ranch, Rancho Santa Margarita, Coto de Caza.
Why hire Maksbuilder:
1. The licensed contractor (CSLB #1095368) is on every estimate and inspects every install.
2. A factory-trained install crew — not subcontractors hired job to job.
3. Engineered installs (real load calculations, not equipment guesses).
4. Rebate guidance and 0% financing.
5. 24/7 emergency response.
Free in-home estimate — typically same-week.

They came out same-day when two other technicians said they could only come out the next day. It was 88°F in our home at 6pm and these guys had it solved and cooling within an hour of arrival. The technician was friendly, fast, and took the time to explain what was going on with the system. They really saved us from a very warm evening, we will definitely be working with them in the future for all our HVAC needs!

Maksbuilder's reply
Thank you so much, Calvin! That kind of situation is exactly why we make same-day AC repair a priority — nobody should be sitting in 88°F heat waiting until the next day for help. We're so glad we could get your system back up and cooling quickly!
Fast response times and clear communication are two things we take seriously at Maksbuilder. Whether it's an emergency air conditioning repair or routine HVAC maintenance, our technicians show up ready to diagnose and solve the problem — not just schedule a follow-up.
We truly appreciate your trust and look forward to being your go-to HVAC contractor in the future. If you ever need heating, cooling, or air quality service in Rancho Mission Viejo, we've got you covered. Thanks again for the kind words, Calvin!

Had an AC issue reported by my tenant. The technician was professional and honest about the situation, offering a monitoring solution after the first visit. While the problem wasn't fixed initially, he followed through by scheduling a second appointment and brought additional expertise to ensure the job was completed properly. Appreciated his commitment to getting it right. Would consider using again for future HVAC needs.

Maksbuilder's reply
Thank you, Julia! We appreciate your patience and understanding throughout the process, and we're glad we were able to see it through to a proper resolution. AC issues aren't always straightforward — sometimes a monitoring period is the most honest and responsible approach before committing to a repair.
We're proud that our technician followed through, brought in the right expertise, and made sure the job was completed correctly. At Maksbuilder, we'd rather take the time to get it right than rush to a fix that doesn't last — especially for rental properties where your tenant's comfort is on the line.
Thank you for recognizing our commitment to doing things the right way. We look forward to being your trusted HVAC contractor for future air conditioning and heating needs in Irvine. Don't hesitate to reach out anytime!
