Frequently Asked Questions

  • How important is an air filter in an HVAC system?

An air filter helps improve your home’s indoor air quality (IAQ) by filtering out dust, debris, allergens, and contaminants. A filter is especially important for occupants with respiratory ailments, like asthma and allergic rhinitis. That’s why replacing your air filters is important, especially if you have shedding pets.

  • What is the difference between a ductless HVAC system and a centralized system?

A centralized HVAC system comprises ducts connected to your heating and air conditioning system—the ducts transport air through rooms in your building. A ductless or split system has an indoor and outdoor unit. The condenser is usually found outside to promote proper air cooling and heating. A split system is ideal for zoned heating and air conditioning.

  • Do I need a programmable thermostat?

To make your HVAC system energy-efficient, you can use a programmable thermostat to pre-set temperature settings at a certain time of the day and in certain rooms. It helps lower energy consumption by automatically lowering your settings if you are not home or in rooms with no occupants.

  • Should I clean my air ducts?

It is important to clean your air ducts, like how you clean your heating and air conditioning units. Dust and debris can build up inside your ducts and obstruct proper airflow. Bacteria and allergens can also thrive in poorly cleaned air ducts, especially where there is moisture. Get a reliable HVAC repair, installation, and maintenance company to thoroughly clean your air ducts at least once every two years.

  • Do you provide emergency HVAC and air duct services?

The licensed technicians at HVAC Alliance Expert are available 24/7 should you need urgent services. We provide same-day and next-day emergency HVAC services, which you can avail of even on weekends and holidays.
