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: Should you buy a house with a 15-year-old HVAC?

• <div><p>You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit&rsquo;s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout. </p></div>

Q: How long does my AC need to be off to unfreeze?

• <div><p>This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn&rsquo;t overflow. When you turn the system back on, keep an eye on it to ensure it doesn&rsquo;t start freezing again.</p></div>

Q: How much value does a new or upgraded HVAC system add to a home?

• <div><p>A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home&rsquo;s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.</p></div>

Q: Can you run an attic fan with the AC on?

• <div><p>Yes, you can run an attic fan with the AC on. In fact, you don&rsquo;t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard. </p></div>

Pat brought new life to our older AC unit. His lifetime of experience with AC units cannot be overlooked. Our AC system feels brand new circulating air in places we had previously never noticed. Thank you Pat! - Chris (Granada Hills)

"I called and they sent someone out the next day. They were prompt and efficient and most of all the swamp cooler was repaired. The price they charged was excellent. I also signed up for a maintenance contract based on how well they took care of this problem. There are not a lot of places left who service swamp coolers so this was a good find. I have already recommended them to my sister for service on the air conditioning system in her home."

"I highly recommend Belle Air Services! From the first moment I called to get a quote, to the moment they finished the job, I could not have asked for better customer service, top notch work, and competitive pricing. They communicated with me all throughout the process, made sure I understood everything that would be done, were on time, protected my home and were clean. They even worked very well with my HOA (who is very tough!). And to top it off, they didn't try to up-sell me as other HVAC contractors have in the past. So pleased that I have found this HVAC company!!"
