Q: Why is my AC blowing cool air but not cold?

• <div><p>If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.</p></div>

Q: Should my HVAC damper be open or closed?

• <div><p>Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent <a href="https://www.angi.com/articles/troubleshooting-common-air-conditioning-problems.htm">common AC problems</a>.</p></div>

Q: What shortens the life of an air conditioner?

• <div><p>While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.</p><p>Some things that shorten your AC&rsquo;s lifespan include:</p><ul><li><p>Extreme outdoor conditions, like high humidity or extensive salt spray </p></li><li><p>Improper installation</p></li><li><p>Extended run times, either by the unit being too small or the thermostat setting too low</p></li><li><p>Not performing required maintenance</p></li></ul><p></p></div>

Q: What is the $5,000 rule for HVAC systems?

• <div><p>The $5,000 rule for HVAC systems helps homeowners decide whether to <a href="https://www.angi.com/articles/it-time-repair-or-replace-my-air-conditioner.htm">repair or replace an AC</a> or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it&rsquo;s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system. </p></div>

Q: Is the AC motor covered under warranty?

• <div><p>It depends on the specifics of your warranty. The motor is likely not covered if you&rsquo;re working with a limited warranty. The same goes for other components like the compressor and evaporator coil. Some extended warranties will cover the blower and fan motor, so read the fine print before signing up. Additionally, the manufacturer may offer a warranty for the parts, including the motor, though there&rsquo;s likely to be a strict time limit for this coverage. </p></div>

IÃ¢Â Â ve used a couple of other technicians but Kyle will be my go to moving forward. He kept me informed of everything he was doing and educated me on how my unit should be running. He even gave me info for what filters I should be purchasing to help my unit run efficiently.
