6. What type of air filter should I use for my Ultra V Tech 80, and how often should I replace it?

Choosing the right air filter for your Ultra V Tech 80 furnace is essential for both air quality and furnace performance. The recommended air filter size will be specified in your furnace manual. The size is usually printed on the side of the filter itself as well. Typical sizes are 16x25x1, 20x20x1, and 14x25x1 (inches). Also ensure the filter’s MERV rating matches the recommended rating by the manufacturer.

Types of Air Filters:

• Fiberglass Filters: These are the least expensive option, but they offer minimal filtration. They are primarily designed to protect the furnace from large particles.
• Pleated Filters: These filters offer better filtration than fiberglass filters and are effective at removing dust, pollen, and pet dander. They are a good balance of filtration and affordability.
• Electrostatic Filters: These filters use an electrostatic charge to attract particles. They offer good filtration and are reusable (but require cleaning).
• HEPA Filters: These are the most effective filters, capable of removing 99.97% of particles as small as 0.3 microns. However, they can restrict airflow and may not be suitable for all furnaces. Consult your furnace manual or an HVAC technician before using a HEPA filter.

MERV Rating: The MERV (Minimum Efficiency Reporting Value) rating indicates the filter's ability to capture particles. Higher MERV ratings mean better filtration. For residential use, a MERV rating of 8-12 is generally recommended. Using a filter with too high of a MERV rating can restrict airflow and damage your furnace.

Replacement Frequency:

• Fiberglass Filters: Replace every 30 days.
• Pleated Filters: Replace every 1-3 months.
• Electrostatic Filters: Clean every 1-3 months (follow the manufacturer's instructions).

Factors Affecting Replacement Frequency:

• Air Quality: If you live in an area with poor air quality or have pets, you may need to replace your air filter more frequently.
• Allergies: If you have allergies, you may want to use a higher-MERV filter and replace it more often.
• Usage: If you run your furnace frequently, you may need to replace the air filter more often.

Regularly check your air filter and replace it when it appears dirty. A clean air filter is essential for efficient furnace operation and good indoor air quality.

7. Does the Ultra V Tech 80 furnace have a pilot light, and if so, how do I relight it?

Most Armstrong Air Ultra V Tech 80 furnaces do not have a traditional pilot light. They typically use electronic ignition, which eliminates the need for a constantly burning pilot flame. This is more energy-efficient and safer.

However, some older models of the Ultra V Tech 80 might have a pilot light. Here's how to determine if you have one and how to relight it (if applicable):

1. Look for a Pilot Light Access Panel: Check the front of your furnace for a small access panel labeled "Pilot Light" or something similar. If you see one, your furnace likely has a pilot light.
2. Follow the Instructions on the Furnace: There should be instructions printed near the pilot light access panel on how to relight the pilot. Always follow these instructions carefully.
3. General Steps for Relighting a Pilot Light (If Applicable):
   1. Turn off the gas: Locate the gas valve on the gas supply line near the furnace. Turn the valve to the "OFF" position. Wait at least five minutes to allow any accumulated gas to dissipate.
   2. Locate the pilot light assembly: Remove the pilot light access panel. You should see a small tube leading to the pilot light assembly.
   3. Press and hold the pilot button: Locate the pilot button (usually red or black) and press and hold it down. This releases gas to the pilot light.
   4. Light the pilot: While holding the pilot button, use a long-handled lighter or match to ignite the pilot light.
   5. Continue holding the pilot button: Continue holding the pilot button for about 30-60 seconds after the pilot light is lit. This allows the thermocouple (a safety device) to heat up and keep the gas valve open.
   6. Release the pilot button: After 30-60 seconds, slowly release the pilot button. If the pilot light stays lit, you're done.
   7. Turn the gas valve back on: Turn the gas valve back to the "ON" position.
   8. Replace the pilot light access panel: Secure the access panel.

If the pilot light does not stay lit, or if you smell gas at any time, turn off the gas valve immediately and contact a qualified HVAC technician. Do not attempt to relight the pilot light if you smell gas.

If your furnace has electronic ignition and isn't starting, troubleshoot other potential causes first (e.g., thermostat, circuit breaker, air filter).
