Get matched with top air conditioning pros in Sun Valley, CA

Q: What happens if my whole-house generator is too small for my AC?

• <div><p>An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home&rsquo;s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.</p></div>

Q: Should I worry about my AC unit getting rained on?

• <div><p>The outdoor portions of air conditioners are designed to weather the rain, so you don&rsquo;t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.</p></div>

Q: How do you know if your AC compressor is burnt out?

• <div><p>There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.</p></div>

Q: How do you know if something is wrong with your HVAC?

• <div><p>Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.</p></div>

Q: How do I service my HVAC system?

• <div><p>In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren&rsquo;t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.</p></div>

"Excellent service and a very professional company. Jeff our sales person worked with us to determine a cost effective Lennox ac system that would fit my needs, without trying to up sell us to a more expensive unnecessary system unlike the other two ac companies that had quoted us. He even included one free extra year of maintenance! The crew was punctual and answered any questions that we had. The installation was a difficult one that took the entire day because our original ac unit was very old and it was not easy to remove. The installation crew did an excellent job and went above and beyond the standard installation. They went the extra step to wrap, tape, and tidy up the insulation on the HVAC ducts, which was not part of the contract. The foreman showed up towards the end of the installation to do a quality and control check, show me how to use the new system, and answer any questions that I had. He even went the extra step by providing and installing a second WIFI thermostat at no charge! Now we have a very efficient and quiet system for the upcoming summer heat season, thanks to the exceptional service and quality installation provide by Around The Clock Heating and Air Conditioning!"
