🚨 When was the last time you changed your air filter?

It’s one of the simplest maintenance tasks homeowners can do, but also one of the most overlooked!

Here’s a general rule of thumb:

🔹 Every 30 days: Check your filter for dirt and buildup.

🔹 Every 60–90 days: A common replacement interval for standard 1-inch pleated filters.

🔹 More frequently: If you have pets, allergies, heavy dust, or your system runs constantly.

A dirty filter can restrict airflow, increase energy consumption, and even cause your heating or cooling system to shut down!

💡 Harborside Tip: Don’t just go by the calendar. Check your filter regularly and replace it when needed. Thicker media filters may last considerably longer.

🔥 When the flames are coming OUT of your boiler instead of staying IN… you’ve got a serious problem! 🚨

During a recent service call, we found this 80% efficient steam boiler showing multiple signs of serious failure.

🔥 Flame rollout: As you can see in the video, flames were escaping the front of the combustion chamber instead of remaining contained beneath the boiler. This can indicate a compromised combustion chamber, blocked flue passages, or other serious venting and combustion issues.

💧 Water leaking from the boiler: This steam boiler was also leaking water directly from its front section, raising concerns about the integrity of the cast-iron heat exchanger.

🚨 Safety switch tripped: The flame rollout had become severe enough to trip the boiler’s safety switch, shutting the system down to help prevent overheating and a potential fire.

Why is this dangerous? Escaping flames can damage surrounding components, create a fire hazard, and indicate combustion problems that may also increase the risk of carbon monoxide exposure.

This is exactly why annual boiler maintenance and proper safety inspections are so important. A heating system can have serious underlying issues long before a homeowner realizes something is wrong.

🔥 DON’T FALL FOR THE “CRACKED HEAT EXCHANGER” TRICK.

A failed heat exchanger is serious — but you shouldn’t be told you need a new furnace without being shown why.

On this system, we didn’t just take a quick look and make a guess. We tested it.

We scoped the heat exchanger from the top and from inside the furnace, where we found significant rust and deterioration. We also tested the supply air and measured carbon monoxide present in the air being delivered into the home.

As you can see in the video, we also observed abnormal flame behavior, with the flame being pushed/back-pressured toward the face of the furnace — another indication that something wasn’t right and needed further investigation.

A proper diagnosis means inspecting, testing, documenting, and showing the homeowner exactly what was found.

If someone tells you that your heat exchanger is cracked or compromised, ask them to show you the evidence. And if you’re not comfortable with the diagnosis, get a second opinion from a qualified HVAC professional.

Your heating system is a fuel-burning appliance. Safety deserves more than a sales pitch.

Original circulator pump… and it’s definitely seen better days. 😬

Rust, corrosion, and years of wear eventually catch up with every heating system. Your circulator pump is responsible for moving hot water from the boiler throughout your home—and when it starts to fail, your heat can suffer right along with it.

Don’t wait until the first freezing night to find out your heating system has a problem. 🔥

Another oil-to-gas conversion underway in Weymouth! 🔥⚓

For this homeowner, the biggest concern wasn’t the boiler — it was oil. Rising and unpredictable oil prices, worrying about deliveries, and making sure there’s always enough fuel in the tank had become something they simply didn’t want to deal with anymore.

Instead of replacing this Buderus boiler, we’re converting it from oil to gas with a new burner, allowing them to keep equipment that still has life left while changing their fuel source.

If you’re tired of watching the oil gauge, scheduling deliveries, or wondering what your next fill-up is going to cost, give Harborside a call and see what options make sense for your home.

$5.98 a gallon for heating oil. 😳

❄️ Quick HVAC tip: Your thermostat brand is NOT necessarily the brand of your AC system!

See a Honeywell thermostat on the wall? That doesn’t mean you have a Honeywell air conditioner. Nest? Ecobee? Same thing.

Your thermostat is simply the control for your heating and cooling system. The actual brand of your AC—Carrier, Trane, Lennox, Goodman, Mitsubishi, Bosch, etc.—can usually be found on the outdoor condenser or the equipment label.

Why does this matter? When you call for service, knowing the actual equipment brand and model can help your HVAC technician arrive better prepared.
