"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."

"Service was great and pricing very competitive. Nick Knuth was very knowledgeable when he came to do an assessment of the work to be done, and answered all my questions I'm a very clear way. The techs worked pretty quickly and efficiently when installing the new unit. Deisy and Emma from the office always made sure that things were taken care of and went above and beyond with follow-ups and updates. I would definitely recommend them to anyone who needs this service."

"I am writing this review after a year because I wanted to test it out and provide an honest review. We replaced our AC unit with a new one with the help of NathanD. He was extremely professional and offered us the best price compared to all the other companies we considered. The installation process only took half a day, and they also installed a Google Nest for us. Additionally, they assisted in fixing our broken circuit board in the garage. Overall, the workmanship was excellent, and NathanD answered all of our questions. He even followed up with us after 2 months to check on our satisfaction. We initially found him through Angie's List."

"Before, we only had a localized very old gas floor furnace. Total Home Environmental installed a centralized Heating/AC system in the attic and insulated the attic as well. They installed vents and ducts (first time for the house). They did a good job."

"Initially I considered having to pay $8000-ish for a replacement unit. Robert Alfonso saved the day, however. Well trained by LA Tech, and professional from start to finish, Robert diagnosed and resolved my wiring and capacitor issue quickly. The fix was $485 not $8000 to replace the unit. These guys are legit. Great result. Robert "Doctor" Alfonso rocked it."
This is the outdoor unit that offers 17 SEER Hyper efficiency and super quiet operation of 54db's compared to 80 plus on older units
notice the low profile, this is about 14 inch wide instead of the traditional 36 wide.

"RKM made this almost a pleasure. We started with a service call to evaluate/fix the old A/C. Richard was on-time, skilled and helpful. RKM phoned to confirm appointments and sent email messages to keep us updated re: arrival times. When new equipment was needed - Robert helped us navigate the choices and design a system that was a more efficient Energy Star rated unit that met our needs at a price we could manage. We didn't need financing but, that was available as a reasonable option. Proposals, invoices and equipment brochures were all sent in detailed & easily understood email messages. Installation of the new system (furnace & A/C) went smoothly as scheduled. The installation team - Jonathan, Brian and Julio - were on-time, friendly and knowledgeable. They took care to protect our homes interior and yard. All of the old equipment was removed and new installed, tested, etc in one day. The new a/c compressor, made by Gorman is QUIET; It's only been 24 hours but, the house is COOL and we can't hear anything in the house or yard."

"Nick returned calls promptly and arrived on time.  I asked him to text me when he was on his way, and he did.  He was nice to work with and explained our options along the way.   He initially came to our house on 4:30 on a Monday.  Then he came back Tuesday with the first necessary part.  He then ordered the new furnace and installed it on Sunday, which was perfect for us, since we didn't have to take time off from work.  The replacement went smoothly.

"The technician, Tony, did a great job. He was friendly and professional, and promptly installed my new water heater. My old water heater had failed the day before and flooded my basement, and they were able to come the next day to replace the water heater and get my hot water back online.

"I hired Air Care to replace my ducts. They were not the cheapest but they were by far the most professional and quick to respond. I have experience in the construction field and kept a close eye on the installation. I can say these guys are true professionals. They took care to protect my home and did their job in a very efficient manner. They answered every question which is what impressed me the most. I felt other contractors didn't want to answer my questions or gave me very short answers. JP took time to explain everything in detail and went above the call of duty. I am very happy and Air Care will be my HVAC contractor of choice going forward."

FAQs for central humidifier installation and replacement projects in Los Alamitos, 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.
