"Efficiency Air Inc is a fabulous company with excellent customer service and trained professional installers. I received a quote to install a mini split air conditioner/heat pump and we were overjoyed of the quality of work we received. They showed up on time and installed the system with ease. The install Manager â Deanâ was a true leader and got everything needed accomplished. I would recommend Dean and crew to anyone needing quality service. Thank you again for everything. Your lifetime customer Nathaniel G Santa Clarita, CA"

"Sean was great about repairing my disconnected dryer air duct having to go into the crawl space and figure out what was going on. I'm glad he was able to get it done very quickly as well. He also had a very good attitude about doing the work."

"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!"

"Shai is a classic example of why I prefer sole practitioners. His prices are reasonable and it was clear that he wants his customers to be happy. In my experience, many of the larger heating AC firms up sell things that people donâ t need. I have succeeded by judging people accurately. Shai is hard working, honest, and competent. Small business people like him should be supported. ."

"⭐⭐⭐⭐⭐ We had an amazing experience with Ernie from Upright Construction! He came out to check our AC because it just wasn’t keeping up during this awful heat wave. From the moment he arrived, he was professional, honest, and took the time to explain exactly what was going on in a way we could understand. What really stood out was that he never tried to upsell us or pressure us into unnecessary repairs. It genuinely felt like he wanted to help us fix the problem instead of making an extra dollar, which is so hard to find these days. Thanks to Ernie, our AC is now working amazingly, and our house is finally cool again. We couldn’t be happier with the service we received and would absolutely recommend Ernie and Upright Construction to anyone looking for honest, reliable HVAC service!"

Air Conditioning FAQs, answered by experts

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.

Yes, high-efficiency models reduce environmental impact with lower energy use.
