"Replaced my gas furnace and air conditioner with a heat pump. The only company I contacted who did a thorough analysis of my home and electrical system to determine exactly what I needed. Side note: I requested this service because my furnace quit working. The technician who came out to evaluate my home repaired the furnace for free while doing his analysis. I still bought the heat pump, but this company definitely did not simply try to just sell me one."

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.

"Just had a furnace tune up done at my residence. The young technician, Jesus Morales, showed up on time and he did a great job in performing the thorough inspection to ensure that the system was working properly. I want thank Southland Heating for their seasonal reminders and deals."

"We had ATC take a look at our HVAC system that was not running well. Another company came out and told us the entire installation was wrong and everything had to be replaced, including all ducting. The price was astronomical. They also said that some structural work needed to be done, such as cutting through drywall and the house, which was not included. When Kevin from ATC came out to look, he said the ducting and the heater were just fine. The condenser and coil were old and probably should be replaced but it wasn’t an emergency. He suggested installing a dual controller and an additional return to improve the airflow issue we were having. He also gave us a quote for three options of new condenser/coils, along with financing options. The price was a fraction of the other company and the financing allowed us to do everything now rather than later. John and Kevin came out to do the installation. THEY WERE PHENOMENAL! They arrived on time, were so pleasant to speak with, were exceptionally patient with all our questions, were extremely knowledgeable about HVAC and split systems, were neat and clean, and did an extremely professional job of installation. That included all the drywall work that was necessary! And the improvement we received was unbelievable! Every room in the house was immediately receiving excellent airflow! We really thought we were in trouble, but these guys made sure we got all the cooling/heating we needed throughout the house with as little cost to us as possible. I would highly recommend the company and would especially recommend John and Kevin. They also fixed a split unit that wasn’t working. They can do it all!! Love these guys!"

FAQs for ducts & vents installation and replacement projects in Topanga, CA

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
