Get your minor demolition, remodeling of your property and general handyman service done by Smart Fixers LLC. we take pride in getting your work done right the first time.

"Smart Fixers came to me through Angi to repair my storm door. I was simply interested in getting an estimate. We had an appointment set for the next day. At the time of the appointment, he called me to ask if we had an appointment. He showed up late. The estimate wasn't provided until he was fixing the door. Same applied to the ceiling fan he installed. He also did some other work for me including fixing a couple of doors, changing a filter , assembling a few things and cleaning the gutter. Those were done fine Smart Fixers saw that I was working with another contractor on building a screen room on my deck. He expressed interest in doing the job for a much cheaper price than the contractor. He reassured me that he had done this before and would be able to complete this work within a week. I clearly stated to him that I didn't know anything about constructions (masonry, carpentry, roofing). I had a structure in mind and I hoped for something safe and sturdy from an expert. He charged me for labor and I was responsible for the materials. The estimate that he gave was way off and I inquired about it, he said that he didn't account for taxes. Few things happened: 1. He recommended sheetrock at the base of the screen room and charged me $1000 for this. I soon found out from colleagues and other contractors that these did not belong outside at all. He seemed not to know this. It got me really concerned. I asked for reimbursement and he did so. 2. I also noticed issues with the screens, they weren’t fitted properly and some parts as holes. He didn't seem to check the quality of his work. I had to check every single detail. His original way to address this was to double to screen. I refused and he had to refit them. 3. I ended up buying and picking the doors myself after the ones he was going to buy were not only very expensive but also very poorly rated online. He approved of the doors after I showed it to him. Turned out they didn’t fit the frame. When I asked for the doors to be repaired, he told me that he was operating at a loss and needed to go make money elsewhere prior to finishing the work. I had to research a few things on my own to help with this, but it didn't work. 4. On the day the work was supposed to be completed, I noticed water coming in the roof. He built a roof above the gutter. When I brought it up to him, he kept telling me that he did whatever I asked him to do. Again, who's the expert? He also alluded to the gutter being an issue.. He came back and put glue under my gutter and added a piece of wood to Prevent the rain from coming in. Once tested, no water was coming in. 7. I also noticed that the shingles were not set up evenly on both sides. Again I had to look at every detail of his work because he wouldn't inspect even the most obvious issues. 8. I called a specialist as the work was winding down as I became more doubtful of his skills. Those specialists reviewed the work and pointed out various structural defects including poorly framed doors, defective roof that was installed above the gutter. Although the rain was no longer grossly coming in the screen room, with time it was going back into the soffit and eventually damaging the house. I did pay Smart Fixers in good faith and in the hope that he was going to address all my concerns properly eventually. He refused to address the gutter and the roof claiming that he did what I asked and the gutter was the issue. I find myself having to pay $485 just to remove the sheetrock . Almost $8000 for repairing the roof so it doesn't damage my house in the future. This guy was way out of his debt although he will never acknowledge that. I should have done my homework properly. I wanted to support a man trying to build his business. Cheap is never really cheap when it comes to construction. If you are looking for someone to do random small jobs in your house, maybe Smart Fixers is for you although there are plenty of people out there. For construction and larger projects, proceed with caution or go with someone reputable."

FAQs for central a/c installation projects in Nassau, NY

If you’re replacing an old AC system with a new unit, you can usually clean and repair the old ductwork without having to conduct a full replacement. Cleaning HVAC ducts typically costs around $400, while repairs range from $200 to $1,000. In contrast, installing new ductwork can range from $1,000 to $5,000, making it far more costly than cleaning or fixing existing ducts. HVAC installation costs an average of $7,000 to replace a full system, so staying on top of maintenance and repairs is important.

AC cost efficiency depends on the size of your space and your long-term plans for your home. If you only need to cool a small area, a portable AC unit has a low upfront cost. Heat pumps are typically the most cost-effective option if you want to cool an entire home or improve the resale value. They provide strong cooling while being energy-efficient, which saves you money on your utility bills compared to most other AC types.

Installing a central AC unit typically takes four to eight hours if your home already has ductwork in place. However, if new ductwork needs to be installed, this can add another one to two days of labor to your project.
