Frequently Asked Questions
How often should I replace my air filter?
Air filters require replacement every 30 to 90 days. The actual timeline depends on several factors, including usage, pet dander, excessive dust, and debris. High-efficiency filters may also require more frequent replacement.
What are the signs that my furnace needs repair?
Several signs suggest that your furnace needs repair, including:
- Uneven or insufficient heating
- Strange noises
- High utility bills
- Frequent cycling
- Pilot light problems
How can I improve the efficiency of my HVAC system?
Regular maintenance is one of the most effective strategies for optimizing HVAC system efficiency. This includes cleaning and adjusting, replacing filters, and other tasks to keep your system running smoothly and with minimal strain. Upgrading to a high-efficiency unit can also have significant impacts on your energy consumption.
Other ways to improve HVAC energy efficiency include:
- Sealing leaks and gaps in ductwork.
- Upgrading home insulation and sealing door and window gaps.
- Installing a programmable or smart thermostat.
- Keeping vents open and unobstructed.
- Changing air filters regularly.
Why is my AC making strange noises?
AC systems run with a low hum, and they typically don’t exceed a decibel equivalent to normal speaking levels — abnormal, loud, or persistent sounds indicate an underlying problem. Rattling, clanking, banging, and screeching sounds are usually associated with mechanical problems, such as worn-out belts or motor bearings. Hissing may indicate refrigerant leaks, while whistling suggests airflow problems.
