Choosing the right Heating and Air Conditioning Contractor is very important. Chances are you are going to make a substantial investment in your new HVAC system with which ever contractor you choose. There is nothing worse than investing a large amount of your hard earned money in a new system and winding up with a system that is noisy, inefficient, and does not perform properly. Or even worse, one that fails prematurely. Surprisingly enough most HVAC Contractors have no formal training. Untrained HVAC Contractors frequently do not size systems properly which could result in improper cooling, very high utility bills, and even systems that fail prematurely. Before you even consider a contractor make sure they are NATE Certified and Air Balance Certified. North American Technician Excellence is the Prestigious Certification of HVAC Competence. Using a NATE certified contractor is like using a surgeon that graduated Harvard Medical School with honors. Air Balance Certified contractors understand airflow which equates to efficiency and comfort in your home. To have a system designed properly a contractor has to understand air flow. At Southland we offer this high level of expertise. Yes, we are very good at what we do and there is no question about that. Our reviews and ratings prove that. Our installations are unparalleled with every system being designed specifically to the home. All options for a quality installation are included in every system we install. From basic systems, high efficiency systems, to specialized zoning we do it all. If you are searching for a knowledgeable contractor you have found one here. We offer extremely competitive pricing and expert design knowledge.

I have been in the construction businesses for 20 plus years, and can do anything you want. I have worked in many areas of construction for example remodeling spaces, painting, building structures and so forth. I am independent owned.
"Easy communication. I needed a bathroom exhaust fan installed where there is no attic access. The project included wiring and ductwork to the exterior as well as drywall removal and repair, and then finishing everything beautifully. The two-man team of Vasquez did as instructed and also fixed some old shoddy work that was in the way of the new duct and wiring. They used good materials and did good work at a good price. They were also very respectful of my home, keeping the mess contained and cleaning up after. I would hire again."

FAQs for central humidifier installation and replacement projects in Huntington Park, CA
Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.
With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.
It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.
Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.
If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
