"So many GREAT things to say about Air-Tech. First, I had a split system installed on one side of a duplex about 10 years ago. It was permitted and passed. Less than a year later I learned there were leaks/problems with it. The original installer wouldn't come back as they no longer worked in this geographical area and the European units weren't being used. Thank God they recommended Air-Tech! They fixed the system and offered an annual maintenance check where they come out every 6 months and check for leaks, clean filters, etc. Their office is so wonderful about reminding me if I have forgotten to set up an appointment. Their guys are ALWAYS professional, clean and courteous. Well, two months ago the tenants in the other side of the duplex requested AC and I knew Air-Tech would be great. I called Alex out (what a super nice guy) and he came over the next day I think. I remember it was a Saturday. Since the price of these system had gone up substantially from when I bought it ten years I was shocked. I signed the contract and gave him a deposit but after talking to BF he suggested I get other bids for something that expensive. I called Alex and asked him to put my project on hold for a week while I looked at bids. I think he was surprised because I knew them and the system but I felt like I needed to be prudent. He wasn't rude or short. He was very respectful. The other company's estimators were pleasant enough and I learned about some options for a second gas heating system that I wanted installed at another location. The other company's prices were similar. One added a city inspection which I was doing as an added cost ot Air-Tech's price and the other company added five years of maintenance onto their price. So the prices were a bit higher. I knew I'd be purchasing the maintenance services from Air-Tech so I knew how that compared. I called Alex back about a week later and said: "Let's go. Thank you for the time to check around and feel confident. Armando and Andrew have installed the systems this week and I could NOT BE HAPPIER. I am amazed that Armando knows so much about electrical, gas and mechanical systems. Andrew is very helpful and knowledgeable and quick to make sure things are clean. Every time someone has come out from Air-Tech they are nice, neat, respectful and focused on their work. They aren't taking calls on their phone, they aren't talking excessively, etc. ANYWAY, as part of the installation for the gas wall heater they discovered that there are two gas leaks under the raised property. Someone had installed temporary shut off valves for two previously serviced gas units (a floor furnace and radiator we think). Yikes! Air-Tech was supposed to be done with ALL the work yesterday and while it's not as convenient to be at the property another day I am so thankful that they found the leak and are fixing them without charging me any money! How can they do that? I think it's because they know I'm a loyal customer. I'll be purchasing the maintenance contracts. Thank you Alex, Armando and Andrew. So happy to be working with you!"

"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"Bill Walker is the tech that diagnosed my faulty condensing unit compressor to be grounded. Sounds like a good thing right? but its not. You never want to hear that. Should you ever do so you want Trabuco Air handling it. I was explained what was wrong and given options that i could comfortably choose from without just breaking the the already shaking bank. Trustworthy and reliable Bill is a cool cat and confident in his skill set. He knows air conditioning extensively and will solve your needs as well. I can finally enjoy the upstairs again thanks to Bill from Trabucco Air."

"Well, I started having problems with the AC when it got a bit hot about a week ago, but, Simon came to check the system, determined that nothing was wrong--what happened must have been a fluke. The visit was complimentary."

"Ray is very professional, and provided options for my air conditioning unit replacement. Ray went out of his way to replace a small gas line leak that he found. He also drove to Anaheim early on Saturday morning to pick up a part that was needed for the AC unit, and came over to install it so that I would have the air conditioner available for the upcoming heat wave this week. He and his team were on time, and considerate during the installation process. I highly recommend RS Air Conditioning & Heating."

"I had a gas valve and water valves that were woefully old and needed replacing. I read the reviews for All City and was impressed so I gave them a call. From the beginning, the experience was fantastic. Jasmine answered my call and was pleasant, informative, and answered all of my questions. She was able to get someone out to my house in a day! The day of service I received a text from my tech, Ruben, letting me know he was on his way, and he was early at that! I can’t say enough great things about Ruben. He is friendly, professional, knowledgeable, and just an all around cool dude! He had my gas valve fixed within 15 minutes, which is no small task. The valve and piping are over 50 years old. I was impressed with how quickly and thoroughly the job was done. He had to come back the next day to replace the water valves so we made an appointment for the next morning. Let me first say, I am an early riser. I jokingly told Ruben this the prior day when asked what time he could arrive the next day, we set the appointment for 9am (I’m already up for 3 hours normally). At 7am I get a text that he is on his way, Ruben followed this up with a phone call making sure it was ok to come that early. OF COURSE! Again, he showed up smiling and ready to go. Despite the challenges of the ancient pipes he had the job done in no time. He was also kind enough to provide new hoses for the washing machine. Additionally, he actually made a run to the hardware store to get a longer gas hose to accommodate where I intended to position my stacked washer/dryer! Let me emphasize again, I cannot say enough great things about Ruben and the service I received. He went above and beyond any expectations and was able to get a job done that I thought near impossible. People like him are rare these days and not only does his personal work ethic shine through, but by proxy he makes All City a cut above and beyond all plumbing companies. I will defiantly be using them, and requesting Ruben, for all of my plumbing needs moving forward."

"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

Air Conditioning questions, answered by experts

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.
