  1. What is HVAC, and how does it work?

HVAC stands for Heating, Ventilation, and Air Conditioning. It’s a system designed to control the temperature, humidity, and air quality in your home. It works by using various components such as a furnace or heat pump for heating, an air conditioner for cooling, and a ventilation system for air circulation.

  1. How often should I change my HVAC filters?

The frequency of filter changes depends on several factors, including the type of filter you use, the level of pollutants in your area, and whether you have pets. As a general rule, check your filters every 1 to 3 months and replace them when they appear dirty. A clean filter ensures efficient airflow and better indoor air quality.

  1. Why is my HVAC system making strange noises?

Unusual noises like banging, clanging, or hissing can be a sign of underlying issues. It could be loose parts, a clogged filter, or even a malfunctioning component. If you hear strange noises, it’s best to schedule an inspection with a professional technician from Nation Furnace Heating & Air Conditioning HVAC Ltd. to diagnose and address the problem.

There are several ways to boost your HVAC system’s efficiency:

– Regular maintenance: Schedule annual tune-ups to keep your system running at its best.

– Sealing and insulation: Ensure your home is well-insulated and free of drafts.

– Programmable thermostat: Use a programmable thermostat to optimize temperature settings based on your schedule.

– Clean filters: Change filters regularly to maintain efficient airflow.

– Upgrade to energy-efficient equipment: Consider replacing old, inefficient units with newer, energy-efficient models.

  1. What is the ideal indoor humidity level, and how can I control it?

The ideal indoor humidity level for comfort and health is generally between 30% and 50%. You can control indoor humidity with a humidifier or a dehumidifier, depending on whether you need to add or remove moisture from the air. Some HVAC systems also have humidity control features.

  1. Is it necessary to have my HVAC system serviced annually?

Yes, annual HVAC maintenance is essential. Regular maintenance helps prevent breakdowns, extends the life of your system, and ensures it operates at peak efficiency. Neglecting maintenance can lead to higher energy bills and costly repairs.

  1. What should I do if my HVAC system isn’t heating or cooling properly?
