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."

I started "I'll Handle It" to address what I recognized as a need that homeowners have for competent, knowledgeable and courteous home improvement service professionals to help them with all manner of projects large and small. Founded in San Diego, "I'll Handle It" is a home grown business that prides itself in its responsiveness to its customers needs. At "I'll Handle It" "Professional Service You Can Rely on" is our mantra, and we can prove it.

"Dave was great! The best communication and transparency I've seen in a long time. Dave explained what he needed to do to install the dryer vent and got right to work...NO wasted time. He installed the vent and made sure it was working properly. The vent looks great! Dave is knowledgable, professional, and a nice person. He also stayed in touch, letting me know how soon he would arrive and when he was on his way. I really appreciated that. We will definitely call him the next time we need a handyman."

"Carini installed my mini splits a few years ago and promised me the world with their warranties. Well, turns out they botched something during the install and all of the refrigerant leaked out. They want $2,200 to refill and re-pressurize the line. Since they cross-threaded the screw that led to the leak during installation, this should be covered under the "Lifetime Craftsmanship" guarantee. Instead, they're trying to charging me a full day of labor to fix their mistake. Support on this issue has been dismal. It's been 16 days since they first diagnosed the problem and I still don't have a timeline for when this will get fixed. I chose Carini because of their warranties and their service record, but its all smoke and mirrors. You've been warned."

Heating and Air Conditioning questions, answered by experts

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Next, find the “reset” button on your AC unit and hold it for three to five seconds. The unit should beep several times. If your air conditioner doesn’t have a reset button, leave the circuit breaker off for 30 minutes. Afterward, turn the power back on at the breaker and program the thermostat to “cool” to test the system.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.
