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."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"We are having our HVAC replaced and our salesperson recommended DUCTZ. DUCTZ came out on-time today to clean our air vents. The communication prior to the visit was very clear and it was easy to understand the upcoming process. They were very considerate, we toured our home and they went right to work bringing in the needed equipment and moving necessary furniture to access the vent covers. They were diligent and stayed focused on the task. Before I knew it, they were reattaching the cleaned vent covers and removing the equipment. Within a few hours, we had before/after pictures and have a great sense of comfort knowing all the gunk is gone! I highly recommend DUCTZ!"

Heating and Air Conditioning questions, answered by experts

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

Not necessarily. Some portable air conditioners may be vented out a door, wall, or ceiling—or even into another room. It’s not necessarily dangerous to run a portable air conditioner without venting it, but it is counterproductive since the unit needs to vent the heat in order to cool the room down in the first place. Without venting your portable AC unit, you’re essentially running a dehumidifier and increasing the temperature in the room. 

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
