"As a former licensed building contractor and well respected by the building commission in Colorado Springs, CO, I must say that HD Mechanical Inc. superseded my expectations. Brandon was excellent! They were very considerate and laid a tarp on all the floors to minimize trash or dirt on the floor. Brandon came over very considerate to my needs and "did not" try to up sale me on other services that others do such as installing new venting when it is not really needed. They pulled the permit in Downey, CA and it easily passed. He communicated with me every step of the way. The receive 5 stars from me!"

"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."

"Everything went as smoothly as can be imagined. Darrow was easy to work with when planning the job. He worked with my attention to details as I chose the AC and heating units that I wanted and, at my request, put every detail in writing. It was a big job - completely replacement of two systems on two floors including roof mounted AC and basement and attic furnaces. His crew were respectful, professional and always on time. The work proceeded exactly as it was described. Construction messes were cleaned up at the end of every workday. The work was finished on time. As in every big project, there was a "punch list" of details that needed to be attended to. Darrow came out immediately and took care of ALL the details big and small on the list. The new heating system worked perfectly and efficiently this winter. I'm looking forward to seeing the new AC system work this summer. I spoke to a number of companies and got a number of quotes for the work to be done. Darryl wasn't the least expensive - his quote fell in the middle range -- but he was responsive, adaptable and communicative. Very glad I chose his company for the work."

"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.

"Gustavo quoted the job for me and gave me several options.  I could have just replaced the AC, or added the duct replacement, or do the whole thing and replace the furnace too.  I think it is rare for a company owner to be so compassionate and intent on solving his clients and customer's needs.  I had told him I had some unexpected expenses and this repair had come at a difficult time.  That's why he helped with giving me choices.  In the end, I decided to replace the whole system.  The tenants are delighted with how fast the system works and I was very impressed with everything about my experience.  I would strongly recommend them!"

"Nick Sinclair handled my project. He was really great. I had no clue that you had to have a permit in order to install a furnace or water heater. An inspector came out and told me that I would need a permit. They had to drive from Orange County to Riverside County in order to get the permits. These guys stopped everything, drove out there and took care of all the permits. They installed everything promptly and it was just the perfect job. Their prices are fantastic."

"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.

"Poor Communication. Angie's List told me this company will call me two days after I purchased the service. Well, guess what? I had to call them after 7 days when no one bothered to call or email me. Their reason: "you did not leave us your contact number." Hello??? Don't you have it in my AL's account? This is the only company I dealt with from AL that asked for my contact info.

Poor Service. When the technician came with only 3 small tools in one hand (may be 3 screw drivers) I thought he had no intention of cleaning my furnace according to the contract. True enough, after looking at my furnace and let it run for a few minutes he told me my furnace is defective and needs to be replaced. He was sorry to give me the bad news but he will send me a quote for a brand new furnace system. Well, guess again? The quote never came...no calls, no nothing! He was in and out of my house in less than 10 minutes. That was easy!

I ended up cleaning the furnace myself, thanks to YouTube. Now my furnace is running good and I'm enjoying my warm winter.

There is a good reason for the B Grade for this company. The only reason I hired them is proximity and low price. But as they say: you get what you pay for!

FAQs for central humidifier installation and replacement projects in Signal Hill, 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.
