"I had AC Dave preform three jobs for me over the past few years. (1) New ducts a few years ago. (2) Installed a mini-split heat pump in master bedroom this year. (3) Then a few months later I had him remove my old Central AC and replace it with an 18 SEER heat pump and new coil, all the while leaving my old furnace in place as a back up. Dave and his guys did a great job on all three projects, completing each one in a day. Highly recommended."

"It went very well. The technician, Oleg, was on time, fully masked and following safety protocols. He quickly diagnosed problem, replaced the part not working, and cleaned out dryer vents of accumulated lint. The price was fair and dryer now working fine. I use Around the Clock for my AC/Heater annual service and now will be using them for any appliance repairs needed."

"I wasn't sure I was 100% happy with the design of the new duct system they were going to put in, but the installers added another vent to improve the air flow to one room that did not get circulation, so I am very happy with the work they did!"

"I highly recommend Trinity A/C & Heating. Our air conditioning system stopped working, so we called another company to diagnose the problem. After a brief inspection, including a trip to the attic, they told us we needed a completely new duct system at a cost of nearly $8,000. Fortunately, we decided to get a second opinion and called Trinity A/C & Heating. Jimmy thoroughly inspected the system and quickly identified the real issue: the system was simply low on refrigerant. They fixed the problem for a little over $300, and the A/C has been working perfectly ever since. Jimmy and Mike were honest, professional, knowledgeable, and took the time to explain everything clearly. Their integrity saved us thousands of dollars and prevented us from paying for unnecessary work. It's refreshing to find a company that puts honesty and customer service first. If you need A/C service, do yourself a favor and call Trinity A/C & Heating before making any major repair decisions. Thank you, Jimmy"

"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 always had airflow issues in my house, I always thought it was normal, until I decided to reach out for help. Mario with CoolPros Heating and Air came out and gave me a free evaluation. He found most of my ducts had holes, and had major air leaks. I decided to replace with him for a great price he gave me. The quality of service and customer experience was beyond my expectations. Thank you. . Coolpros heating and air! I already referred my sister and she’s having her system installed next week!"

"Don Lusk worked with me to address a tear in my duct work rather than replacing all the runs (which other companies suggested). He thought outside the box to find a good solution. Pleased with customer service and clear communication. They showed up on time and completed the work in a timely manner. Courteous crew. I recommend this company and have also switched to working with them in the future through a yearly service contract (at my request)."

We were particularly impressed by the exceptional level of cleanliness he maintained, ensuring that every surface was spotless and devoid of any clutter. His professionalism was evident throughout the entire process. The pricing was also highly reasonable and transparent."

FAQs for ducts & vents installation and replacement projects in Los Angeles, 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.
