Commercial HVAC Services

Most homes in the U.S. rely on furnaces for heat, though boilers and heat pumps are also common options. No matter the type, all heating systems follow the same basic process: they bring in cold air or water, heat it using a fuel source, and then distribute the warmth through ducts or pipes. Since these systems have many interconnected parts, a single malfunction can lead to broader issues. 

If your furnace is making unusual noises or your heat pump seems to be struggling, MacBrothers Mechanical is here to help. Our technicians are trained to service all major heating systems and focus on thorough, long-lasting repairs—not just quick fixes.

Air conditioning systems cool your space in three main steps. First, they pull in warm air. That air is then compressed and passed over a refrigerant-filled coil, which cools it down. Finally, the cooled air is circulated throughout your home via ducts or vents.

Because AC units are complex, it’s best to leave repairs to the professionals. At MacBrothers Mechanical, we service all brands and models. Whether it’s a faulty thermostat or a worn-out part, we’ve got the tools and experience to get your system running smoothly.

The right AC size depends on your home’s square footage and layout. A unit that’s too large may cool the space too quickly without properly managing humidity, while a unit that’s too small will struggle to maintain a comfortable temperature and use more energy in the process.

To determine the best fit, we conduct a detailed inspection and use the Manual J load calculation. This helps us recommend a system that matches your home’s specific heating and cooling needs.

Your ductwork plays a crucial role in your HVAC system’s performance. If it’s too small, too long, or obstructed, airflow will be restricted and efficiency will drop. We can inspect your ductwork to ensure it’s in good condition—and if it needs cleaning or adjustments, we can take care of that too.

There are many types of HVAC systems, each with its own advantages. Here are a few of the most common:

• Split systems: These have indoor and outdoor units connected by refrigerant lines and are widely used for efficient cooling.
• Packaged systems: Installed outside, these are compact and often more affordable.
• Variable-speed furnaces: These operate at lower speeds for longer periods, improving energy efficiency and comfort.
• Heat pumps: These provide both heating and cooling and are ideal for regions with mild winters. They’re also more energy-efficient than traditional furnaces.

If you’re unsure which system is right for you, we’re happy to help you explore your options.

A quality thermostat can make a big difference in comfort and energy savings. Many modern models are programmable and offer features like remote control and energy usage reports. We offer the Nest thermostat and other smart options—contact us to see which one is compatible with your system.

While it’s not always necessary to replace everything at once, doing so can improve system compatibility and efficiency. Mismatched components may not work well together and could lead to performance issues. Whenever possible, we recommend purchasing equipment from the same manufacturer to ensure everything works seamlessly.

Installation times vary depending on the system and your home’s setup. While some installations can be completed in a day, others—especially those involving ductwork or larger systems—may take several days. We’ll provide a clear timeline and keep you informed throughout the process.

The best time to replace your HVAC system is during the off-season—typically spring or fall—when demand is lower. This can lead to quicker service and potential cost savings.
