"Bill and Trish exceeded the expectations I had from the start. Trish is so pleasant to talk with that you forget quickly you are asking for a service and not talking to a friend. Bill is a craftsman who has many years of experience and he gets right to the point of where your problem lies. In our case the tune up for the summer was not realistic when our 30 year old AC unit had leak issues. Bill and I worked through several scenarios regarding cost of a repair and an investment in a new unit. It made sense to do a new unit and not worry about our old AC unit further breaking down and requiring more repair. Bill and Trish advised us of a cancellation that allowed the new AC unit to be installed 3 days after the service call. Bill and Trish followed through on their quote, and arrival time for installation on time. Everything I was told with a time frame was on time,accurate, and made sense to what I was receiving. Raphael and Nisho were assigned my install and they were no different regarding their punctuality and care for our house. Bill and Raphael took me through the complete process of what would be done and when the project would be finished. Raphael and his crew treated my house well making sure to drop cloths down everywhere they worked. I could not tell they did anything because of the cleanliness in which they worked. The job was made easier as Raphael helped me to clear the work area I was supposed to clear. I was running late in clearing and Raphael helped me to clear the area without complaining or having me do it on my own which was my job. After the installation Raphael walked me through our new AC and also provided valuable recommendations on how to take care of our new unit. What I must stress is everyone from Cool Air Technologies goes above and beyond what they need to in making sure you are 150% satisfied. Raphael helped me pick quality new air filters for our AC on Amazon to make sure we knew exactly what to purchase. Bill followed up that afternoon to ensure I was satisfied and encouraged any questions I might have. The AC unit performs exceptionally. The old unit if I turned it on in the afternoon to cool the house it could only drop the temperature by a degree or 2. Our new unit brought the temperature down from 78 in the house to 74 degrees in less than an hour. We still have 30 year old ducts and vents that do not allow the best air flow so this is a great improvement. Bill installed a new AC that cost me $3,000 less than what I was quoted 2 years ago from another company. My wife and I are extremely pleased with the service provide by Bill, Trish and his crew. I love they are family owned and they have your best interest at heart when they come out and do a job for you. Please use Cool Air Technologies for your service needs. It's such a pleasure when you get to deal with honest hard working local family owned companies that take pride in their work and word they give you."

"Michael was knowledgeable and very informative. The installers were competent, outstanding, and courteous. Aire Care’s bid was more budget friendly compared to other major local companies. The crew promised to get installation done in 2.5 days but completed the work in 2 days with an additional install. All in all, we would go with AireCare Heating and Air any day. We highly recommend AireCare Heating and Air."

"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.

"After returning home from 2 weeks away to find my A/C unit not working, I had another contractor come out for a service call. They just listened to the unit and said I needed a new air conditioner. They gave me a quote for $3350. I decided to get another opinion and called All Day upon a recommendation. Josh came out the same day, listened to the unit and removed to panel to find the capacitor was bad. Replaced it for $120 and my A/C is up and running great. I recommend All Day Heating and Air and would gladly call them again."

"Noticed one of my bedrooms wasn’t getting the same air pressure as the others. I called the guys at sky clean air and was scheduled for the following day for a free quote. Nadav and Erick were on time and quickly got to work, because the age of the house the duct connected to the spare room had become brittle and damaged. I was given a quote for the single duct and replacing the attic I was never pushed into making a decision. Ended up going with the single duct and work was done same day with before and after pictures. My experience with Sky Clean Air is the type of business you want to deal with never felt like I was being played. Definitely recommend"

Air Conditioning questions, answered by experts

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.
