"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contractor and well respected by the building commission in Colorado Springs, CO, I must say that HD Mechanical Inc. superseded my expectations.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!"

"Got a great product for the $$ I spent, the installers did a great job and were very professional and took the extra time to make sure my system provided adequate air supply to each of the registers in my home. Had on miscommunication on when the workers would show up, but it was handled and all is good."

"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."

"The BEST phone call I have made this year for a service needed in my home was to Mirsky Heating and AIr. I called in the middle of a So. Cal heatwave because my thermostat had stopped working and I needed to replace it. How often does an AC company, in the middle of a heatwave, tell you they can come the same day? NEVER!! Except for Mirsky..Darrow told me that he would try to make it work..and he did...which I will be forever grateful!!! He checked in with me during the day to assure me that he was coming and not to leave work until he was more clear on the time he would be at my home. He showed up with another Mirsky employee named John..they were both super friendly and so helpful. Darrow found the problem and within 45 minutes, the thermostat was replaced and everything was up and running again. I can't say enough how grateful I am to Darrow and Mirsky Heating and Air...I am giving their contact info to all of my friends and will be calling them again for anything heating AC related."

"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.
This replaces your old gas heater

"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.

FAQs for central humidifier installation and replacement projects in Costa Mesa, 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.
