"Air-Tech installed a 3 zone Mitsubishi mini-split system in our home this in September. We got quote from five companies for the system and decided on Air-Tech because of Larry’s knowledge and experience. The bid from Air-Tech was competitive. Air-Tech was not the lowest priced bid we got, but quality is worth paying for. I can say that out of all the HVAC companies we have worked with over the years Air-Tech surpasses them all by leaps and bounds. When I say this, I am coming from a place of experience. We have built our own house and we come from a family of architects and builders. We also had just finished working with another company (that shall remain un-named) around the same time to replace a different central air system. That other un-named company completed the job late, charged a higher price than what they proposed, and left our house and property a mess. Air-Tech however was knowledgeable, prompt, clean, trust-worthy, and professional. Larry even went out of his way to get our project done faster than their schedule should have allowed at the time. They were scheduling months out when I called during the big heat wave of the summer, but he got our project done in three weeks anyway. I had explained to Larry that we were without heating or cooling at the moment and really needed help. I did not tell him that the urgency was because my terminally ill mother was coming to stay with us and she needed good climate control. While Larry didn’t know about my sick mother, he was able to understand the urgency in my tone I suppose. Larry put an extra crew on the job and oversaw the work himself. The fact that Larry came through for us made such a difference in our lives at the time. I am sharing this story to demonstrate that at the end of the day Air-Tech is a company of people who want to help people and on top of that they are excellent at doing what they do. PS. I also enjoyed the Holiday Card they sent us this year."

"HD Mechanical did an excellent job. After trying to fix my water heater, the tech offered me two solutions, the first to repair the old unit and the second to replace it. I chose to replace the unit because it was 20 years old. He was able to return in two days and spend many hours at my home. The tech was courteous, professional, explained everything and made sure everything was working properly before he left."

"We have used Darrow before for our unit and the condo association and were extremely satisfied. We called him again when our heating unit stopped working. We called on a Friday afternoon and we asked if he could come out the next day or Monday and he insisted that we not wait (since we were having a cold spell) and came out the next day and worked around our schedule. He's friendly, knowledgeable and his price is always fair and reasonable (and he didn't charge extra for a weekend). He also diagnosed the problem right away and didn't try to sell us things we didn't need. He also noticed on the roof a problem with our neighbor's unit and he replaced the cover to a water spout so they wouldn't get water leaking in (and did it at no charge). We're always apprehensive any time we have to hire someone for repairs, but Darrow has proved himself to be our go-to person for heating (and air conditioning should we need that). He has a great work ethic and cares about his customers."

"Southland gave us the best quotes for our Heat/AC unit replace. They also told us about rebates from Los Angeles (other businesses we contacted did not mention this). Their crew were professional and worked hard. We especially appreciate the care of Nick and Elbert from Southland. The unit went up in a day and looks great (and works very well, too). We are grateful to Southland for the good experience and excellent customer service. Thank you!"

"I can't possibly rate this company high enough. I am very pleased with the professionalism of the office staff and the professionalism and promptness of my service person, Chris. My preventive maintenance window was from 10:00 a.m. to 2:00 p.m. and Chris arrived at 10:00 a.m. He set about to check out my A/C system, added R22 (is it still called Freon?) coolant and cleaned my A/C unit. What was also refreshing is that I did not get a hard sell for any additional products, services or systems.  I am a new customer and will be a repeat customer. I asked if they also maintain and service heating units and received a yes answer. They will see me again for sure."

"Breezeway was very nice. They were prompt and did a good job. However, we negotiated them fixing one piece of ducting. They didn't fix it and said that, if we found that it continued to have problems, they'd come back and repair it. Well, it needed to be repaired when it was clear that it still wasn't working. Breezeway became unresponsive to numerous attempts to get in touch. So, while I thought they did a great job in the beginning, their lack of follow through left a bad taste in my mouth. For that reason, I'm not going to call on them again.

FAQs for central humidifier installation and replacement projects in Altadena, CA

A crawl space dehumidifier is a worthwhile investment, particularly in humid climates or if you've noticed musty odors, mold growth, or wood deterioration. Though costs range from $3,000 to $9,200, this investment helps prevent structural damage that could require far more expensive repairs later. Beyond structural protection, a properly dehumidified crawl space contributes to better overall indoor air quality and may reduce allergens throughout your home. Consider having a professional assessment to determine if your specific situation warrants this investment.

Addressing crawl space moisture effectively often requires a combination of solutions. A complete approach includes encapsulation plus dehumidifier installation. For minor moisture issues, a basic dehumidifier starting at $1,500 may suffice, while severe problems in larger spaces could require systems costing up to $14,000. The most effective moisture control strategy depends on your specific conditions, making a professional assessment valuable for determining the most cost-effective approach for your situation.

For a crawl space measuring 1,500 square feet, you'll need a dehumidifier with a daily capacity of 30 to 50 pints, with unit costs ranging from $150 to $600. Your local climate and existing moisture levels may necessitate adjusting this capacity—homes in particularly humid regions might benefit from higher-capacity units. Professional installers can measure your specific humidity conditions and recommend equipment that is appropriately sized, balancing initial cost with operating efficiency for your unique situation.

Crawl space dehumidifiers add $300 to $500 to your annual electricity expenses when operating continuously. Energy-efficient models reduce this consumption by roughly 15 to 30% compared to standard units. Most contemporary dehumidifiers feature humidity sensors that automatically cycle operation based on current conditions, helping manage energy usage. Proper crawl space encapsulation significantly improves efficiency by creating a controlled environment that requires less dehumidifier runtime, thereby reducing ongoing electricity costs.
