We Offer Comprehensive Plumbing Services in Delaware

There is much more to plumbing than the layperson may understand. All of your pipes, water lines, and drains are interconnected in a vast network hidden behind your walls and beneath your floors. But our plumbing contractors have the experience necessary to provide repairs or replacements whenever problems arise. Among our areas of expertise are:

Water and Sewer Line Repair

Not only will a broken or damaged water line make routine activities a hassle, but it may also put your health at risk. Damaged or broken water lines can flood your property, introduce pollutants and chemicals to your drinking water, or result in a loss of water for your entire Delaware home. The highly-trained plumbing contractors at First Class HVAC can provide professional water line repair and replacement to restore function quickly and efficiently.

Sewer line damage presents additional risks to your home and family. If you notice gassy smells near your home, backups when you flush your toilet or drain your sink, or septic wastewater pooling in your yard, reach out to our team immediately. We will unclog sewer lines and repair any other issues promptly.

Sump Pump Installation

Proper sump pump installation is essential for any basement or enclosed crawlspace. Without it, your home or business is vulnerable to structural issues, mold, and other safety problems. Our plumbing technicians can visit your home in Delaware or Maryland to evaluate the quality and durability of your sump pump to ensure your home is safe. When necessary, we are adept at replacing or installing sump pumps to guarantee your home’s protection.

First Class HVAC services a wide range of water heaters, delivering professional installation and repair for customers throughout Delaware and Maryland. Access to hot water is one of life’s luxuries that many take for granted until their morning showers are frigid. If this happens to you, contact First Class HVAC immediately. We can install and repair tank water heaters and tankless water heaters, whether they are heated using electricity, gas, or solar power.

Toilet Repair

Toilets are not items to which most people devote much thought. They are never more than a couple of rooms away and a necessary element of any home, but they are normally just there. However, when an older toilet experience frequent clogs or causes increased water bills, it may be time for a replacement. First Class HVAC professionally installs new toilets for homeowners in Delaware and Maryland who need an upgrade. Contact us with any repair questions or to schedule your new toilet installation.

Well Water Pump Installation and Replacement

A well water pump is responsible for drawing water upward and into your home or designated water system. It relies on centrifugal force to pull the water, using spinning rotors to create a vacuum. Unfortunately, well pumps do not display many symptoms when they are beginning to fail. As a result, it is difficult to plan for replacement. You will not have much time to react when you need a new well pump or pressure tank, so contact First Class HVAC when you notice any of the following:

  • Fluctuations in water pressure
  • Sputtering faucets
  • Scalding hot water
  • Unusual noises from the water tank
  • High electric bills

Do not get stuck with no water when you are already late for an important meeting. Solicit the services of First Class HVAC’s expert plumbing contractors for well water pump replacement or installation at the first sign of trouble.
