"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day.

Full installation service lpg and natural gas company, tankless water heater specialist residential and commercial instalations.

"We built our home 4 years ago and even before we moved in, there were issues with our water system. We went through 2 professional companies that supposedly specialized in our newer system, but the issues kept on happening. Last Minute Inc. was the only company who discovered what was dangerously wrong and corrected the many issues. Carlos and his employee were punctual, professional, and experts in dealing with our issues when other who professed knowing what they were doing, failed. Thank you so much"

"I've never experienced such high quality from a construction company in Miami before. Their work outside was comparable to finished carpentry inside. I've never seen anything quite like it before in my life. They couldn't have done it any better and I'm quite critical when it comes to the work so they did a good job."

Water Heaters questions, answered by experts

Replacing an older water heater that requires frequent repairs is almost always worth it. If your fixture is nearing the end of its life span—around 10 to 20 years, depending on the model—replacing a water heater might save you money in the long run. Replacing a water heater generally costs less than repairing a fully flooded basement, and some high-efficiency units pay for themselves thanks to energy savings. Plus, installing a new water heater and upgrading to tankless will boost your home value and make your hot water more readily available, improving comfort for your family.

When investing in a new furnace, it’s smart to do a home energy audit. That will give you a list of any projects that would help with efficiency, such as sealing or replacing windows and insulating the attic. You can also take this time to install a smart thermostat if you don’t already have one to make heating your home a breeze.

Installing a water heater costs about $1,300 on average. The overall price ranges from as low as $880 to as high as $1,800, depending on the type of water heater and any additional plumbing work required to fit the new water heater. Other cost factors for this type of installation include the tank size, tank vs. tankless, fuel type, vent system, permits, location, and labor cost for installation.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.
