Expert Heating Services in Saint Paul

Home Heating System

Saint Paul winters are known for being pretty brutal, with temperatures often reaching lows of 10℉. Reliable heating is crucial for those cold stretches from November to the end of February, which is why we prioritize top-quality installation and maintenance solutions.

Don’t panic about returning home from the Saint Paul Winter Carnival to a broken boiler or malfunctioning thermostat – simply call 4Front today!

Upgrading Your Boiler

Has the pilot light gone out? Or maybe you’re suddenly noticing cold spots. Whatever the problem, we’re on hand to repair those broken boiler components. Our expert technicians can also help you choose the most energy-efficient replacement if your boiler is beyond repair or more than 12 years old, from leading brands like Daikin and Mitsubishi.

We also install versatile in-floor radiant heating to keep you toasty with every step. These systems work on virtually any surface and offer 20 to 40% better efficiency than other heating options!

Furnace & Heat Pump Installation

Being so close to the Mississippi River creates scorching summers and frigid winters for Saint Paul residents. Energy-efficient heat pumps work for both, using air transfer to warm and cool your home whenever you need it most. Give 4Front a shout and we’ll help your indoor spaces achieve better temperature control today.

Is your furnace making strange noises or not circulating air properly? We’ll replace the filters or recommend the best gas or electric furnace replacement.

Whichever heating option you prefer, we’re here to help.

Choosing a Gas Fireplace

There’s nothing better than coming back to a cozy home after watching the Minnesota Wilds win at the Xcel Energy Center. Gas fireplaces warm your rooms without hassle, needing minimal maintenance to keep running. 

Choose from vented or ventless built-in, modern gas inserts, or log sets that mean you won’t waste time chopping wood and clearing ashes.

Keep Your Cool with Our AC Solutions

While you may enjoy that cool breeze coming off of Pigs Eye Lake, what’s not so great is the humidity from the wetlands. Handling temperatures that surpass 70 degrees in the summer requires effective air conditioning – and that’s where our air conditioning services come in:

  • AC Repair: Is your unit leaking or blowing hot air? Our trusted technicians offer prompt repairs at any time of day so you won’t be left to deal with discomfort this summer.
  • Routine Maintenance: We’ll replace your filters, check refrigerant levels, tackle any loose components, and clean blocked vents to keep your home nice and cool.

Professional Electrical Repair & Installation

Faulty smoke alarms and loose wiring may be disruptive, but they’re also extremely dangerous. Besides HVAC, we’re also skilled in the latest electrical solutions to ensure your home stays fully powered and safe. Our Saint Paul services include:

We also offer a complete remodeling service and conduct electrical inspections to keep your Saint Paul property safe at all times.

Saint Paul Plumbing Services

Unfortunately, frozen pipes are common for Saint Paul homes during the winter – even those in the developing Downtown area. Rapid repair is vital for preventing more costly fixes later on, like bursting or flooding.

Whatever your plumbing issue, from leaking toilets to faulty faucets, get in touch today and we’ll ensure your systems run smoothly all year round.

Water Heaters

Hot water is a must-have for every Saint Paul home, from the preserved Victorian Summit Avenue to the more modern West Seventh. We have plenty of water heating options, including tankless or traditional (and gas or electric), so you’ll always have enough for cooking and cleaning. 

Sump Pumps

Snow melt may not seem like much of a problem during the January Winter Carnival. But when the spring comes around and the ice begins to disappear, Saint Paul properties – especially those with basements – are prone to flooding. 

Rely on our reliable sump pump systems to reduce the risk of water damage and electrical issues, even throughout the rainy season.

Garbage Disposals

Foul odors and jammed blades are major issues caused by broken garbage disposals. Luckily, we can quickly spot and repair the early warning signs of a garbage disposal problem to keep your home clean.

Drain Cleaning

Fed up with slow-draining sinks or standing water? These are both indications of blocked drains. Invest in our professional drain-clearing service and we’ll get rid of tree roots, leaves, food waste, and anything else that could be clogging up your system.

Excellent! They saved me thousands by fixing the broken refrigerant line. Other places would have pushed me to get a new HVAC. The a/c is only 9 years old so I am thrilled that they were able to fix it. This is where experience and skills…

We were in a must replace situation with our furnace. We had four bids and theirs was by far the best. The whole crew was professional and did a great job. The furnace and ductwork are great. Fully recommend them.
