"We couldn’t have been more pleased with the level of professionalism used by DayCool as a whole! As new residents to Alabama, we were apprehensive about looking for a company we could trust. After looking for several companies and having multiple come out for estimates on a unit replacement, we decided on Day Cool because of the owner’s down to earth speaking style and breaking it down for HVAC-challenged! We bought a unit from them which they warrantied AND an air scrubber...I think that’s the name...it’s already working! Best decision we’ve made for our family of four and one pup! I’m super excited! Thank you to the team that came out today! They worked all day in our house after arriving promptly! The staff on the phone was also very hospitable and accommodating! Thanks, DayCool! You’ve got my business!"

"Jeremy was terrific. I've dealt with a lot of A/C contractors, and only a few have been so honest, dependable, and diligent in their work. The estimate was a lot less than the others (a total of under $6K for 3 units - a 6.5 ton and two 3-ton systems). Everything was done professionally, with attention to detail. Even the work area outside was swept clean after the job was done."

Heating and Air Conditioning FAQs, answered by experts

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

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 common AC problems.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.
