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.

The blower motor had failed, and I also wanted the heat exchanger cleaned while the system was being serviced. Kolby clearly explained the problem, walked me through the available options, and gave me an honest assessment of what needed to be done. There was no pressure and no attempt to upsell me on anything I did not need. The total repair cost, was, fair for the work performed and within the budget I had discussed. Most importantly, Kolby got everything taken care of quickly and had my air conditioning back up and running in no time. It is refreshing to work with someone who is straightforward, knowledgeable, and respectful of the customer. I would definitely recommend Cozy Home Services, and I would not hesitate to ask for Kolby again.

They took my money, failed final inspection, and have not come back to fix it…read more I see the owner, Jason, replied to another person with a similar problem that they "do not have any Install's that are left incomplete." This is not true, at least in my case, and I'm happy to give him the permit number if he gives ME a call--I'm tired of calling and emailing and getting not reply. I hired Cozy Home Services in January 2026 to swap my ducted gas furnace for a heat pump at my home in Oakland. The main installation went smoothly, but what followed has been deeply frustrating. When it was time for final inspection, they told me to schedule it myself, even though their contract says they do the permits. The first inspection failed with nine correction items. It took weeks of follow-up and the intervention of a third party for me to get Cozy Home to send someone out to make the fixes. When the technician arrived, it was clear they had not reviewed the correction notice or checked with the city. He asked me what needed to be fixed, then called his manager for guidance, and ultimately said he would do what he could and 'we'll see how it goes.' They even installed the wrong fix--an unnecessary second breaker box on the outside of the house. That second inspection (which I also had to schedule) failed with six items still outstanding. These are not complicated fixes, either--things like swapping in a GFCI breaker, putting in a proper p-trap on the condensation drain, and other items that are listed right in the blower installation manual. That second failure was six months ago. They have not come back and the permit is still not finaled. During the installation, they also cut up my existing filter box rather than replacing it with a properly sized unit as they promise under their own "right size guarantee." They removed the side of the box and replaced it with a loose sheet of metal, ruining the latching, gasketed door to the filter slot. Now I have to untape the door to change the filter, then tape it shut again. This is not a permanent or professional solution. I have made repeated attempts to get them to work with the city. Their responses are sporadic and commitments are not kept. The equipment itself seems fine. The problem is entirely with follow-through, workmanship on the details, and responsiveness after the sale.

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.

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.

We bought a new home sometime around October 2025 and have a homeowner warranty. When we had an issue with our heater, we contacted the warranty company, and they sent Rendon Heating & Air to our home. Rendon assessed the unit and told us it could not be repaired and needed to be replaced, which our home warranty covered. Rendon came back and installed the new unit. While it seemed like it was working at first, it clearly was not. We were told everything was working properly, and since we are obviously not the subject matter experts, we trusted them. However, we continued to have a strong feeling that something was wrong with the heater. This is a gas heater, and every time we turned it on, instead of starting normally, there was a loud **PUFF** sound that literally sounded like the gas was about to explode. On top of that, it would take forever for the heat to come through, sometimes running for 20 minutes without properly heating the house, and we could smell gas. We contacted the warranty company again, explained the issue, and they sent Rendon back out. We explained everything to the technician. Their answer? The unit was working fine and the PUFF sound was "normal" when the heater starts. Ummm... okay. So we asked, is it also normal for the heater to run for 20 minutes without properly heating the house while we can smell gas? Their quick answer was that we needed to replace the entire unit with **their machine** and move away from the manufacturer's machine. Keep in mind, this was a NEW unit that THEY had just installed. Months passed, and we still had no real resolution. At that point, we decided to bypass the warranty company completely because we did not want them sending Rendon back to our house again. We paid out of pocket and contacted two other heating companies for independent assessments because we wanted multiple second opinions. Sure enough, both companies raised concerns. We were told that the gas line/pipe could be malfunctioning or improperly installed because a gas heater should NOT start with that type of PUFF sound. They also identified concerns with the air and gas flow and told us the installation could create a serious safety hazard. Based on what we were told, we decided to have the gas shut off and not use the heater until the issue is properly resolved. This is the part that makes me angry. We repeatedly told Rendon what was happening, including the puffing sound, lack of heat, and smell of gas, yet we were told everything was "normal." Instead of taking our concerns seriously and thoroughly investigating the problem, their solution was to tell us to replace a practically new unit with another unit from them. And the customer service experience did not make things any better. The lady I spoke with constantly talked over me, would not let me finish explaining the situation, and repeatedly questioned our concerns. She even questioned why we had waited this long to check the heater and why we weren't using it. OMG... why would I turn on the damn heater when it was 80+ degrees outside? And when we did turn it on to test it, we repeatedly reported the same problem and were repeatedly told there was nothing wrong with the unit. The entire experience has been absolutely ridiculous. More importantly, when a customer reports a potential gas issue, it should be taken seriously. We trusted Rendon because they were supposed to be the professionals. After this experience, I personally would not trust them to work on our home again.

An email (with the tech's name and picture) and text was sent when he was on his way which is nice. Art did not rush the inspection and was very thorough. He took time to explain what he was doing and what he was checking for. Also took time to explain what maintenance items needed to be completed. Then provided a thorough report of the maintenance items needed and cost if they were to perform them.

Richard saved me a premature $10k+ AC and furnace replacement! When dealing with such a large potential repair or replacement I wanted to get a second opinion.
