After 25 years, my Concord home needed a full HVAC replacement. I did my homework -- four quotes,…read moreverified equipment certifications, asked hard questions about duct sealing, zoning, and equipment sizing before deciding. A-1 answered every question confidently, corrected a spec error in their own quote when I caught it, and put everything in writing before I signed. Install day: Austin, Joey, and Edgar showed up on time. Floors covered, shoes covered, house treated well. Two days -- day one removal and new equipment, day two ductwork and zoning. Heating and cooling tested before they left. Full documentation handed over on the spot. No hidden charges, no surprises, no change orders. Price was mid-range among four quotes, but the warranty structure -- lifetime workmanship, no-lemon guarantee, payment at completion -- made it the best overall package. Still have HERS test-out and city inspection scheduled, but based on every step of this process I'd recommend A-1 without hesitation. Austin, Joey, and Edgar did a great job.

Kudos to Jonathan Meza, Maintenance/Service Tech, for the excellent customer service during my…read morevisit. I reached out to A1 because I am a repeat client who previously arranged installation of a heat pump water heater and a heat pump HVAC system in my home. This visit involved checking a UV lamp that my Ecobee app indicated was overdue for replacement. I discovered, however, that my system lacked a UV lamp. Even so, Jonathan shared more details about my setup and showed no annoyance over a call that differed from the initial report. He described the UV lamp options available for my unit and noted that he would gladly return to install one if I chose to add it to my heat pump system. For all your heat pump system needs, I strongly recommend the team at A1 Guaranteed Heating & Air.

I had the opportunity to use them for some issues at my home. Before I called Brisk, I had called another local company and had the worst possible experience a consumer can have. Lesson learned. BS diagnostics, poor service, and simply tried to rip off a consumer. Tech recommendations were a full system replacement with not clear explanation of why it needed to be replaced. I sent an inquiry to Brisk and shortly received a reply. Appointment booked. Had the pleasure of meeting Kyle who owns the company. Expressed my concerns and issues. Kyle listened and addressed all of them. Did the diagnostics and explained what was going on and what needed to be corrected. He explained what he was doing and what the numbers meant on his gauges. I could not have asked for a better experience with Kyle and his company. Kyle's knowledge in his field is top notch. The world needs more people like him! In the end, Kyle replaced a part. Checked to make sure the system was function within operational parameters. All was good. Nice cool air, quiet AC unit, and a happy customer. Best part is Kyle explained everything and there was no BS. The charge was fair for industry standards. It would not have mattered because if it were more I would have paid it. Simply because Kyle is a true professional! So if you made it this far, call Brisk Heating and Air. You will not be disappointed. They a have client for life and will be the place I call for future HVAC services in my homes. A Big Thank You to Kyle and Brisk Heating and Air!

After years of our guesthouse HVAC system operating somewhere between "mildly haunted" and…read more"emotionally unstable," Adam Eck HVAC finally solved the mystery. For literally a couple years, our previous HVAC company serviced the unit twice a year, came out for additional service calls, nodded thoughtfully at the equipment... and somehow never fixed the actual problem. We eventually accepted our fate and furnished the guesthouse with a space heater, a fan, and what can only be described as climate-related trust issues. Then came Adam Eck HVAC. They were easy to schedule, showed up on time (already a miracle these days), communicated clearly, and actually diagnosed and fixed the issue. Apparently the system was capable of heating and cooling all along. Who knew. They've now taken over our biannual HVAC maintenance for the entire property and did a fantastic job with that as well - thorough, professional, efficient, and easy to work with. Now the guesthouse works consistently, our guests no longer need to dress in layers "just in case," and the portable heater has retired. Professional, responsive, honest, and - most importantly - effective. Highly recommend.

1/5 Stars: PROPERTY OWNERS AND LANDLORDS, BEWARE. DO NOT HIRE THIS COMPANY…read more As a property owner, I strongly recommend that other landlords and property investors avoid Advanced Plumbing Heating and Air. My experience with this company demonstrated a concerning lack of professionalism, accountability, and basic customer service. Before engaging their services, I explicitly established that all findings, concerns, and recommendations regarding my rental property were to be communicated directly to me as the property owner. Apparently, following simple instructions was too much to ask. During a service visit on October 1, their technician disregarded this arrangement and communicated serious concerns regarding my property's heating system directly to my tenant instead of contacting me as instructed. This created unnecessary stress and confusion that I was subsequently left to manage. To be clear, I absolutely expect HVAC professionals to identify legitimate safety concerns. However, there is a professional and responsible way to communicate those concerns, particularly when working with rental properties. Keeping the property owner informed should be a fundamental part of that process. Because of this experience, I made the decision to terminate my business relationship with the company. Their response to losing a customer was arguably the most revealing part of the entire experience. Rather than receiving a thoughtful, personalized response acknowledging my concerns, I received what appeared to be a generic, AI-generated message. They couldn't even spell my name correctly. Think about that for a moment. A property owner terminates a business relationship because of concerns about professionalism and communication, and the company's response is an impersonal, seemingly automated message that doesn't even get the customer's name right. You genuinely couldn't ask for a better demonstration of the very problem that caused me to terminate their services in the first place. It left me with the impression that my concerns were not taken seriously and that retaining my business was of little importance to them. As someone who owns rental property, I depend on contractors who can communicate effectively, exercise sound judgment, and respect established expectations. I should not have to micromanage basic communication or wonder whether a company is even paying attention to the customer paying for its services. My recommendation to fellow property owners is simple: Take your business elsewhere. Find a company that respects your instructions, communicates directly and professionally, and treats your property and your business relationship with the attention they deserve. There are plenty of HVAC contractors who understand that professionalism involves more than showing up with a toolbox. Advanced Plumbing Heating and Air has permanently lost my business. Between the disregard for established communication expectations and the embarrassingly impersonal response to my termination notice, I have absolutely no confidence in their customer service. If they cannot even take the time to spell a customer's name correctly in a response to a formal complaint, I have little reason to believe they will give my property the attention it deserves. One star. I would not recommend this company to any property owner.
