"Service man arrived as expected and performed the annual maintenance of the air conditioning system. The work was thorough and it was something that was familiar to me as I used to do in my younger years. With heavy use of airconditioning in the summer in CA, this is important and something we do every year.

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"Unfortunately, I needed an HVAC company to fix my AC during a heat wave. Most companies were 5+ days out before they could even diagnose our problem. Called 3 highly visible companies, from their marketing, who said they wouldn't even work on our unit. I went with a referral from a neighbor, mistake. This company took a week to get to us then the tech went MIA for 5 days with no contact when he said he would be back tomorrow with parts. Won't mention their name as there could have been multiple uncontrollable reasons why. I then did a lot of research on different companies across multiple review websites (including Angies) and Excel Air stood out. Once I spoke to the office staff, great experience, they had a tech out to our home in 2 days with our problem diagnosed. Our tech's name was Lucas who was efficient with his time, talked me through what was going on and gave us our estimate which we were happy to move forward with. Lucas fixed our problem in under 20 minutes. Me being me, I watched each step and saw the quality work. He even put in a fuse to ensure the same problem didn't happen again to our transformer. Once he fixed everything and got our new thermostat power, our AC has been working perfectly ever since. I'm now a really big supporter of Excel Air. Their office staff worked with our insurance company after hours and actually updated us (what company does this these days) the entire way. I can't tell you how impressed I was from their office, Lucas and most of all their successful resolution of our problems with our AC. Thank you Excel Air!"

"Will came on time and came in and told me had did several of the homes in my area, so he wouldn't need to do a load-test for our home. I felt a little nervous about not doing a load test because I know too small or too big of a a/c unit both have its problem, but I took it on good faith that he knew what he was doing. He asked me what I wanted, I told him just basic a/c unit., as I wouldn't be using it much (just for very hot days). He provided me with 2 options - a complete new HVAC system ($9,545.31) or just an A/C Unit & Compressor ($7,652.31). He also explained that Carini was extremely busy and that they were 1 month out on scheduling any installations."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.

With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"Alex Gold of AirMaxx was personable, knowledgable, and efficient, he came on Sunday of a holiday weekend, and he quickly restored our HVAC. He explained every step, showed the cost of each step, and delivered at the quoted cost. I recommend him and his company for any HVAC issues."

"On initial inspection, they discovered that our old heat registers were the kind with asbestos (house built in the 60's), so they had to sub out the abatement part of the job. Once abatement was complete, the workers showed up each day at the time they said they would arrive. They were all friendly and professional. They kept everything clean. The took pictures in the attic to show me before, during, and after the work. They explained what they were doing and showed me the new ducting they were installing (quiet ducts) and explained the more "up-to-date" way of putting in the duct work than what we had. After the work was complete, we noted that the furnace ran much quieter (due to new ducting), and it ran WAY less often. The house stayed much warmer while running the furnace much less often. Best of all, our gas bill dropped! Now that we're moving into summer, the house seems to be staying cooler on these warm days. We don't have A/C so we're hoping the new insulation will keep the house cooler as the days continue to warm up. Very happy with the company and all the work they did. I would recommend them!"

Heating and Air Conditioning FAQs, answered by experts

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power.
