Hargrave Heating & Air Conditioning provides expert BOILER and COMBI-BOILER installation, repair, and maintenance for safe, efficient, and reliable residential and commercial properties. Our licensed technicians service all major brands and ensure your system runs safely and efficiently year-round.

Boilers & Combi-Boilers

A boiler is a heating system that uses water or steam to distribute warmth through radiators, baseboards, or in-floor heating. Boilers provide consistent, even heat and are known for their energy efficiency and long-lasting comfort.

A combi boiler (combination boiler) is an all-in-one, space-saving system that provides both home heating and on-demand hot water, eliminating the need for a separate water tank. They’re ideal for homeowners looking to maximize efficiency and performance while reducing energy costs.

Whether you’re upgrading to a high-efficiency condensing boiler, installing a new combi-boiler, or scheduling annual maintenance, you can rely on Hargrave for expert workmanship, honest recommendations and dependable service.

Snowmelt Systems

Imagine a winter where your driveway and walkways stay clear of snow and ice without you ever lifting a shovel or spreading salt. Our custom-engineered Snowmelt Systems circulate a warm glycol solution through durable piping embedded beneath your outdoor surfaces.

Why choose a Snowmelt System?

Floor Warming Systems

Nothing beats the feeling of a warm floor on a cold morning. Our Floor Warming Systems turn chilly tile and stone into a source of gentle, radiant heat. Enjoy consistent, draft-free warmth from the ground up for a cozier, perfectly tempered home.

Why Homeowners Love Radiant Floor Warming:

Combination Units

Streamline your home with a Combination (Combi) Unit that handles both high-efficiency space heating and on-demand domestic hot water. These compact, wall-mounted systems eliminate the need for a separate bulky water tank, freeing up valuable floor space while providing endless hot water and consistent warmth.

Why Choose a Combi Unit?

Hot Water Heaters

Ensure your home never runs cold with our high-performance hot water solutions. Whether you prefer a traditional storage tank for high-volume needs or a tankless system for endless hot water and energy savings, we provide expert installation and service tailored to your household's demands.

Key Benefits:

Tankless Water Heaters

Unlike traditional water heaters that store hot water in a tank, a tankless system heats water only when you need it. When you turn on a tap or start a shower, cold water flows through the unit and is instantly heated by a gas burner or electric element, giving you a continuous supply of hot water. You’ll never run out, and there’s no waiting for the tank to refill. Tankless systems are energy-efficient, space-saving and built to last making them an excellent upgrade for any home.

Key Benefits:

Annual Maintenance

Tankless Water Heater Flush

To keep your tankless system performing at its best, Hargrave Heating & Air Conditioning highly recommends annual maintenance ‘Tankless Flush’ for all tankless water heaters. Regular maintenance keeps your tankless water heater running smoothly, maintains maximum efficiency, and protects your investment over time. Hard water can cause mineral scale to build up inside the unit, which can reduce efficiency, water flow, and overall performance.

Our licensed technicians perform a complete annual flush and descaling, gently removing buildup, cleaning the heat exchanger and internal components, and ensuring your system performs at its best year after year.

Annual maintenance benefits:

Maintain Top Efficiency & Consistent Hot Water

Over time, sediment and mineral scale can build up inside your system, forcing it to work harder to reach the right temperature. Regular maintenance ensures your unit operates at peak performance, providing the steady, reliable hot water your family needs while keeping your monthly energy bills as low as possible.

Prevent Costly Breakdowns

Emergency repairs are often expensive and happen at the most inconvenient times. During a routine service call, our technicians can identify and fix minor wear-and-tear issues before they escalate into major mechanical failures. Investing in a tune-up today is the best way to avoid a total system shutdown tomorrow.

Extend Equipment Life

Heating systems are a significant investment in your home. Much like a car, a well-maintained water heater or boiler will last years longer than one that is neglected. Proper flushing, cleaning, and component checks reduce the strain on your system, allowing you to get the maximum years of service out of your equipment.

Keep Your Manufacturer Warranty Valid

Most major brands require documented professional maintenance to keep their warranties in effect. If a critical part fails and you haven't had your annual service, the manufacturer may deny your claim. Regular maintenance provides the "paper trail" you need to stay protected and ensure your investment is covered.
