The salesman & HVAC Manager visited our home twice spending hours, taking pictures of our old system, addressing flaws in our duct work, and addressing our complaints we've had with our old system before preparing their estimate. They showed us all the pictures they took and drew diagrams of what their recommendation was for a total system replacement. Their recommendation included removing our tank water heater to make room for the new air handler. Since there was no room to move the water heater, they recommended a wall mount heater that would not only provide the needed space, but resolve other issues we may have with running out of hot water during showers, eliminating cold bursts during showers, and with their upgraded model we chose, we would have instant hot water ay any faucet. After we agreed to their proposal and the paperwork signed, Michael & Son workers promptly showed up to begin removing all of our old HVAC system, ductwork, plumbing, etc. Suprisingly, the air handler was installed in a different area from that proposed by the salesman & HVAC mgr. Thus being, I could have kept my original water heater. The first plumber to install the wall heater showed up at 4:00pm the same day and rushed through the shotty installation until 9:15pm that evening. He left us with a muddy mess to clean and without hot water because he forgot to turn on the gas. During his time there, he told us of his dislike for the brand of the unit and what we may have not been told at the time of the sale. He said the water heater required a high cost maintenance service call annually to maintain the warranty, and any power outages would result in loss of hot water. That was certainly not happy news to hear but I told him the one and most important reason to keep the heater was instant hot water at any faucet. The plumber looked at me and laughed. He said that would require recirculation and he had no work order for that. When that plumber left, the workmanship was atroshious. Water was leaking from a pipe fitting he didn't tighten, the drain line was running up-hill, he used smeared silicone caulking to seal poorly fitted PVC pipe, and the whole job was really bad. I called Michael & Son the next day to complain and had to wait for the plumbing manager to come out who fixed the leak immediately. The manager pointed out that the installation was unacceptable & would schedule the plumber to return to correct his mistakes. Because of the plumbers bad attitude, haste to get the job done, and overall bad performance, I insisted he send a different plumber. A week later, the 2nd plumber returned and basically had to uninstall the re-install entire unit correctly. When the 2nd plumber notified me he was finished, I asked him about the recirculation upgrade we paid for that had not been installed. He said he would get with his manager and get back to me about finishing. As a result, the plumber was scheduled several weeks later to address the recirculation function. Upon their arrival, they said we should be informed in person rather than on the phone that hot water recirculation would only be available to one faucet of our choice and not all as promised and sold. This was because to perform the recirculation installation, they would have to tear out walls, ceilings, and cabinets to gain access to water lines. That was totally unacceptable to what we were told and redirected our actions to upper management. Finally, after weeks of issues with the expensive $5300 water heater we didnt need from the start, they agreed to remove the wall heater and credit our account and replace it with a tank heater. The HVAC PART: The two HVAC installers Moses & Juan completed the mechanical system installation flawlessly but only as directed. When i asked them certain things about the installation, they said they do what they are instructed, nothing more & nothing less. But after the mechanical component part of the installation was finished, they left and no one came back to check duct air flow or temperature balance in the house. In short, with mild outdoor temperatures, we were experiencing a 6 degree variance from one side of the house to the other and we saw little air flow from most the vents on one side of the house. I called Moses who instructed me to close off all the vents with the "most" airflow to divert air to the others. Two days later I called back to say that it didn't work. Then, he tells me to remove all the vent grilles and inspect for blockages. Again, I followed through this tiring and tedious job which was hurtful to me due to my disability nevertheless, I found no obstructions. I called back a third time where they finally agreed to come out to inspect the problem for themselves. Upon arrival, Moses immediately addressed the 8" duct they were originally were instructed to install which fed the main line feeding the 3 bedrooms and 2 baths, and upsize it considerably with a 14" duct. Then, they closed all other dampeners to 90% closed. MOSES SAID THE SYSTEM SHOULD NOT REMAIN "CHOKED-DOWN" LIKE THAT BECAUSE OVER TIME IT MAY CAUSE PREMATURE DAMAGE TO THE UNIT AND SHORTEN IT'S LIFESPAN. The quick fix showed air now going into the other half of the house but the temperature variance is still 5 degrees when the weather is normal. The interior ducts in most of the house have to remain closed for enough air to warm the bedrooms. THIS IS HOW THEY LEFT US! After complaining profusely, the HVAC Manager was sent out by upper management to analyze the problem. After his thorough inspection of diagrams, pictures, and equation solving, he said the system's air handler they installed didn't produce the volume of air (cfm's) needed to circulate through all of the ducts. I asked how that happened when he said he missed figuring the ducts for half of the house. I then asked what was he going to do to correct the problem when he said he would speak to the salesman about the cost to add zoning which would fix the problem. I advised him that I would not pay another dollar for their errors. He said he would pass than on to the powers that be and left. From then on, we've had to deal with being passed off from one upper manager, who told us we would be taken care of, to another who simply wont do anything. The job is still unfinished and operating poorly for 3 months so far. They're final solution for us: We have to close off all the ducts in the house except the cold rooms to force warm air to cold areas. This would have to be done in opposite every time the system changed from heat to a/c. Or, pay them an additional $3500 (-$500 discount because they care) to fix "their" problem! My wife and I are disabled. We care for my 94 yr old father who can't take care of himself. We just went through the 5 day freezing cold spell where the system couldn't keep up leaving us freezing in the house and us having to use our fireplace for warmth. This proves that the undersized unit cannot keep up with warming our home during freezing temperatures. We called for service but had a lenghty wait on-hold with 57 people ahead of us. By phone message recommendation, I went online and completed an emergency repair request which I received a receipt saying Mike would call me back. I NEVER received a call or visit from Michael & Son leaving us in the cold. The next day, I finally cancelled the request after rebooting the system myself. This is the 3rd time this system has failed in 3 months. It vibrates the floor just above where it's installed and the whistling noise from all the closed vents is very annoying. From this horrible experience with Michael & Son, we've realized and learned some valuable lessons: 1) we were sold items we did not need, 2) they charged us for items they did not replace, 3) their trained professional staff misfigured the ducting and size of the unit, 4)they don't stand behind their work as promised... After weeks of discussion in trying to get them to finish the job and correct their problem, they simply left us in the cold! I WOULD STRONGLY RECOMMEND "N O T" USING MICHAEL & SON FOR HEATING/AC, PLUMBING, OR ON-CALL SERVICE. We hope n
