DO NOT USE MDL Electric Cooling & Heating…read more I do not recommend this company and strongly advise against using them for any HVAC services. I contacted MDL Electric Cooling & Heating on a Friday because my Goodman air compressor stopped working during a heat wave. The owner explained that there would be a $125 diagnostic fee, which I agreed to. A young technician arrived and pulled the 240-volt circuit breaker on the compressor's fuse box. He explained that one of the fuses was dead and further mentioned that the capacitor was a "cheap one" that should probably be replaced as well. He later returned, said he replaced the capacitor and one bad fuse, had me turn on the thermostat, and proclaimed that the unit was fixed. He called his boss, handed me the phone, and I was told the total cost would be $425, payable via Venmo. I explained that the technician had only been at my house for one hour in total, and that even a high-end capacitor costs about $50, with a two-pack of 20-amp fuses costing around $20 at Home Depot. He responded by saying I was paying for the technician's travel time to pick up the parts. I reluctantly paid the $425 via Venmo. About three hours later, around 6:00 PM, the compressor stopped working again. I called the owner and informed him. He said the technician was finishing another job nearby and would circle back in about an hour to see what the issue was. After waiting 3.5 hours, I called back at 9:30 PM and was told I would now have to wait until Monday morning. (Again, this all started on a Friday.) I went outside and pulled the circuit breaker, thinking the new fuse may have blown. To my surprise, the fuse slot was empty. This meant the technician took the dead fuse with him after the first visit, returned to install the new capacitor, but forgot to install a replacement fuse. This was a dangerous situation. My 240-volt motor was now running on 120 volts, and one leg of the circuit was left unprotected from a power surge or short circuit, creating a major fire hazard. I removed the remaining fuse and planned to go to Home Depot the next morning to purchase two new fuses. Upon inspecting the remaining fuse, I noticed it was not a time-delay fuse, as recommended by Goodman and commonly used in air compressors. My first thought was that the $125 diagnostic fee should have at least caught that. So, the HVAC tech had said he replaced the capacitor and one bad fuse, but in reality, only one incorrect fuse was present and the other was missing. The next morning, I purchased two 20-amp time-delay fuses at Home Depot, installed them, and the compressor fired up again. It ran fine for about 20 minutes but then stopped again. I reset the breaker, waited a bit, restarted the unit, and it fired up once more. This prompted further research online, where I learned that airflow issues in the furnace air handler could also cause these symptoms. I shut off the unit at the fuse box, removed the lower air handler panel, and discovered that the air filter was improperly installed. Instead of being inserted from the top by opening the small spring door, the installer had forced it in from the side, where it had become crumpled into a ball, blocked by nearby piping and wiring. This caused a significant airflow obstruction. I returned to Home Depot for a new filter and installed it properly. That was over a week ago, and the unit has been working perfectly ever since. On Monday morning, I called the owner back and told him about the missing fuse. I also questioned why I paid a $125 diagnostic fee when the technician simply checked a fuse and then forgot to install the new one. I also asked for an itemized invoice, which he had promised previously. He said he would speak with the technician and call me back. He also said he would send me the itemized invoice within the hour. I'm writing this four days later. He never called me back, nor did he send the invoice. I even called again to remind him, but still, no response. Do yourself a favor: hire a qualified HVAC company, one that is professional, provides proper documentation, communicates clearly, and stands by their work. At this point, I feel completely ripped off having paid $425 for a capacitor install, with no fuse replacement and no resolution of the actual issue. In the end, YouTube was more helpful than this company. When you say you're going to follow up after doing subpar work, leaving my unit at risk, and charging me for parts and labor you didn't actually deliver, the very least you can do is keep your word. DO NOT USE MDL Electric Cooling & Heating. UPDATE regarding not providing an invoice: Under the Consumer Fraud Act (N.J.S.A. 56:8), any home improvement contractor--including HVAC technicians, plumbers, and electricians--must be registered with the state and follow contractual disclosure rules, including providing an invoice when requested by the customer or if the project is $500 or more, or if the work requires a license.

He painstakingly described the plan for where to put the units in each room, how they would be connected and where the piping would go.

Everytime they came into the house they treated with respect (e.g. by taking shoes off!) and cleaning up all dirt and dust from their work. Outside the work they did was done with extreme attention to detail to blend in with the look of the house.

Michael and his colleague were so nice to deal with from day one. They came to our house to inspect and see what we wanted to do with mini split units. He was honest, respectful and provided sound advice on what worked and what didn't. What's great is that he will respect what you want to do but will give you clear feedback and let you decide next steps. He knows exactly what he's doing. Installation took two days and they were efficient, humorous, so respectful of your property, and overall really kind people. My husband and I are so pleased with their work. Piping on the exterior of the house could potentially look disastrous but they made it look like a work of art. The coils look perfectly aligned and very neat. Inside, the units hang elegantly and evenly on the walls. He also offered to handle the Con Ed rebate paper work which is fantastic. They came on time despite traffic issues from Brooklyn to Queens. They worked non-stop till lunch time which was 30 minutes and they were back at it. Work went late into the evening as they made sure every nut, bolt, piece, or whatever there was to fix/install was done right. If it looked out of place, they immediately perfected it. I'm shocked at how this installation took two days. They work quick but cautiously. It's an intensive, grueling type of labor. I was tired just observing their work. We highly recommend them! Superb craftsmanship, professionalism and communication. We couldn't be happier with the system we installed and for it to be done by two of the hardest working people we have ever met.

I wish I could give 0 stars…read more I wanted a whole home humidifier installed in my apartment. Jim's son came next day and installed it back in October 2018. It never performed the way it should have, and Jim would not come take a look at it, only trouble shoot over the phone, and tell me Im doing it wrong. After calling the manufacturer, I was told the problem was that it was hooked up to the cold water line, when it needs to be on the hot water line. Took 3 months of back and forth and ignoring my calls for Jim to finally come and switch the line over at the end of January 2019. Almost immediately after entering my home to make the repair, Jim insulted me, saying I don't know anything about these units, and this is the first one in the thousands that he's installed that didn't work properly. He then over tightened the self piercing saddle valve (which I have since learned are against code in the state of New Jersey), causing it to leak. He became confrontational and blamed me for this leak. He then put some tape and puddy on the leak and got it to stop long enough for him to tell me I was all set and left. Sure enough 2 days later, I came home to puddles of water leaking from my HVAC closet. Jim wouldn't return my phone calls and I had to call in an emergency plumber to fix the situation. They told me that self piercing saddle valves are against code in NJ and are a cheap short cut from doing it right and prone to leaking. I paid over $700 to fix this and install the proper shut off valve, and remove the dead saddle valve on the cold water line. Also after installing this humidifier, my furnace now "short cycles", because its not getting enough air to the furnace as air is being borrowed for the humidifier. Ive called a real company to handle this problem. Overall Jim does not know which humidifier to install based on my HVAC needs. He cuts corner with parts that are against code and has created more problems that he solves. My advice call someone else, or at the very least dont let him put a self piercing saddle valve in your house.
