Long Distance Moving & Storage. Household, Commercial, International, Corporate services available. Our Mission is To exceed expectations on every move. We live this day in and day out. Our service is top notch and fully efficient. Our trucks are perfectly equipped for moving with Pads, dollies, Plastic and much more. We provide Long Distance Moves across the entire country, directly from our West Coast HUBS located in AZ, CA, OR and WA. Or, we team with our partner companies to complete moves together. We are proud to provide a service that no other company offers; Dedicated Trucks. This means that your belongings are loaded on the truck and not combined with anyone else’s items (from/to west coast only). They are not transferred to other trucks or facilities in route which causes damage and loss of items (typical with van lines). We have a set loading day and unloading day. This is by far the safest way to ship. Our interstate rates are per 24ft moving van that holds up to 8,500lbs or 1400CuFt. Some customers require one truck and some require more. One truck holds the average 1800SqFt.

"I cannot say enough great things about All Service Moving—and ESPECIALLY Rico and Reyes, who were absolute lifesavers for my last-minute move. After another moving company bailed on me the day before my scheduled move, All Service swooped in and saved the day. Rico and Reyes showed up EARLY, upbeat, and ready to tackle the challenge—even with super heavy furniture that usually requires a 4-person crew. Somehow, the two of them handled everything like pros without a single scratch or ding—on the furniture or either home. What really stood out was how personable, kind, and thoughtful they were. They moved quickly and efficiently, knowing I was paying by the hour, but never once sacrificed care or quality. They were kind to my mom (who was helping me out), and so sweet to my two dogs too. If you’re planning a move, ask for Rico and Reyes by name. They went above and beyond, and I want their team to know what a fantastic job they did. They deserve every bit of recognition. 100% recommend."

With US HOME / STARS AND STRIPES has been servicing homeowners for more than 25 years. Customer preference and priorities are always first. We're very timely with our work and never lose attention to detail. Give us a call for your free estimate.Deal direct with owner. FULLY LICENSED: Suffolk County Nassau County

"I can’t recommend Stars and Stripes highly enough for anyone considering a home renovation. From big projects like installing new countertops and a backsplash to smaller details like fixing the track on my sliding closet doors, everything was completed with exceptional care and attention to detail. What really sets them apart, though, is the trust factor. I’m not someone who’s usually comfortable leaving people alone in my home—but with Stars and Stripes, I never once had to worry. They were respectful, reliable, and I always felt my home was in good hands. It's rare to find that kind of peace of mind with contractors, and it's what will keep me coming back for future projects."

Our expertise also includes rooftop package units, PTAC units, humidifiers, and WiFi thermostats, along with repairs and maintenance on all refrigeration systems.

"Ralph looked over everything thoroughly and gave us an estimate. He came to do the repairs in less than a week. Ralph explained everything concisely and was happy to answer any questions. He is very knowledgeable, reliable, and careful. We have older units that were difficult to take apart and put back together; however, Ralph knew exactly what to do and handled the problem easily. He was very professional, careful of his surroundings, and cleaned up afterwards. He even helped us move some of the furniture back, which was unexpected and kind. Both my wife and I were impressed by his superior service. To top it off, Ralph is a great person! We are delighted with the wonderful job that he did. Highly recommend!"

Heating and Air Conditioning questions, answered by experts

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

You should service your AC at least once per year, in the spring, and twice per year if your unit is 10 years or older. As your unit ages, more maintenance can catch problems early and help the system reach its full lifespan potential, usually 15 years.

Get on your HVAC technician’s schedule in early spring so your unit is ready to go for the season. If you’re doing two inspections per year, aim for one in the spring and one in the fall. You should also service your furnace once per year in the fall.

If your AC refrigerant is low, you may notice that the unit takes longer than usual to cool your home or that your energy bills are higher. You may even feel a warm breeze coming from the vents when the AC refrigerant is low. Don’t attempt to check refrigerant levels yourself. Only certified AC repair pros should check and refill refrigerant.
