WHAT TO DO ?
At Harbourgreene, we understand how stressful it can feel when something in your home’s HVAC system stops working the way it should.

That’s why we’ve created this homeowner troubleshooting guide—to help you quickly identify simple problems you can safely check on your own before service is required. These steps are designed to save you time, prevent unnecessary worry, and keep your home running smoothly. And if you ever need assistance beyond the basics, our team is always here to support you with dependable, professional care.
Not blowing HOT or COLD air ?
If your furnace isn’t blowing hot or cold air, start by checking the basics: ensure the thermostat is set to the correct mode, verify the furnace switch and breaker haven’t been turned off, and inspect the air filter—an excessively dirty filter can restrict airflow and shut the system down. If everything appears normal and the furnace still isn’t producing air, the issue may involve the blower motor, ignition system, or internal safety switches. In this case, avoid further troubleshooting on your own to prevent damage or safety risks. Harbourgreene can provide a prompt, professional diagnosis and restore your heating system to proper operation.
Filters
Regular filter replacement is essential for maintaining a healthy and efficient home HVAC system. Homeowners should replace their furnace or air-handling filters every three months, or more frequently if they have pets, allergies, or high household dust levels. A clean filter improves airflow, enhances indoor air quality, and reduces strain on your equipment—helping extend the life of your system and lower energy costs.

Rotten egg smell ?
If you notice a rotten egg smell in your home, treat it as a critical safety concern, as this odor is often a sign of a natural gas leak. Evacuate the home immediately without using light switches, appliances, or electronic devices. Once you are safely outside, contact your gas utility’s emergency line and notify local authorities if needed. Do not return indoors until certified professionals confirm that it is safe. After the issue has been resolved, Harbourgreene can conduct a thorough assessment of your heating system, gas lines, and ventilation to ensure everything is functioning correctly and to help prevent future risks.
