Frequently Asked Questions (FAQs)

At Brogan’s Heating & Cooling, we know that HVAC systems can be confusing. Whether you’re looking for maintenance tips, troubleshooting advice, or information on system upgrades, we’re here to help. Below are answers to some of the most common questions our customers ask.

To keep your system running efficiently and extend its lifespan, we recommend servicing it twice a year, once in the spring for cooling and once in the fall for heating. Regular maintenance helps catch minor issues before they turn into costly repairs.

Air filters should be replaced every 1 to 3 months, depending on factors like pet dander, dust levels, and allergies. Homes with pets or allergy sufferers may need more frequent changes to maintain good air quality.

The size of your HVAC system depends on your home's square footage, insulation, and climate. A system that is too small will struggle to maintain comfort, while an oversized unit may short-cycle and waste energy. A professional assessment can determine the right size for your home.

  • Schedule regular maintenance to keep your system running efficiently.
  • Install a programmable thermostat to adjust temperatures automatically.
  • Seal windows, doors, and ductwork to prevent air leaks.
  • Upgrade insulation to reduce energy loss.

Uneven temperatures can result from several issues, including:

  • Blocked or closed vents restricting airflow.
  • Leaky ductwork prevents proper circulation.
  • Poor insulation in some regions of the home.
  • A professional HVAC inspection can help identify the cause and find a solution.

A programmable thermostat lets you set temperature schedules based on your daily routine. This reduces energy consumption while ensuring your home is comfortable when you need it. Some models even allow remote control through smartphone apps.

You may need to replace your HVAC system if:

  • It’s over 10–15 years old.
  • Your energy bills have increased significantly.
  • You need frequent and costly repairs.
  • The system struggles to maintain consistent temperatures.

If your system shows these signs, a professional evaluation can help determine if a replacement is necessary.

A heat pump transfers heat from the air to warm or cool your home, making it energy-efficient. A furnace generates heat by burning fuel, such as gas or oil, and is often preferred in colder climates for its higher heat output.

  • Change air filters regularly.
  • Clean and inspect ductwork for dust buildup.
  • Keep vents unobstructed to maintain proper airflow.
  • Consider an air purifier for improved indoor air quality.
  • Check the thermostat settings and batteries.
  • Inspect your circuit breaker for any tripped switches.
  • Replace dirty air filters to improve airflow.
  • If these steps don’t resolve the issue, contact an HVAC professional for troubleshooting and repairs.
