"These guys are above excellent! I already had estimates from 2 companies for for a new furnace. One was way too high, and I just didn't feel right about the second one. I called One Hour and got an appointment for a quote the following day. Habib came and took all the measurements for the entire project and gave me an exact price for the work. He explained everything I wanted to know, including the high standards their company follows, from getting exactly the right heating capacity to the requirements for every one of their employees: from drug screening and criminal records to excellent work and cleanup. They have a great guarantee, without any of the usual "membership" stuff that many other companies have. (I asked Habib about the lower estimate from the other company, and he showed me that it was only an estimate that could change. So even though it was lower, it could have ended up being much higher.) The next day, Greg and Ryan came and installed the furnace. Wow! They came and did the work quickly, quietly, and efficiently. They cleaned up afterwards. Greg showed me the new furnace and how to use the emergency shut-offs, and how to change the filter. And he explained how to use the thermostat. I appreciate working with companies that are excellent, and I've found one here! I highly recommend them for any heating/cooling needs."

Indoor comfort is a significant part of life in your home. From heating to cooling, humidification to air purification systems and servicing your equipment, selecting the right equipment and contractor is an important decision. At Robbins Heating and Air Conditioning, we take your indoor comfort seriously. According to Dave Klunder, President, "Our approach is to educate and inform customers about their choices for a properly designed total indoor comfort system."

"DOES NOT CHECK THEIR OWN WORK! I paid for regular checkup and ended up also paying for their recommended replacement of my contactor on the AC unit. After the work was done, I had to leave for an errand and came back to a HOT house, only to find that the tech did NOT turn my thermostat back on. He didn't tell me that I needed to do it, so basically, they're ok with leaving the customer in a lurch and NOT taking responsibility. I also had to call the next day to ask for an itemized receipt, since the tech never left me with a copy of what I paid for. Speaking of, they charged me $280 to replace the $40 part (massive labor charge), PLUS the $99 "service" fee. When they finally sent the invoice after I requested it twice, there was no itemization of the charges at all. This situation was so bad with how Robbins handled this scenario, that my husband called to try and rectify it. This company was recommended to me by my father-in-law, and I had been using them for the last three years. I will NEVER use them again, nor will I be recommending their services. No apology, no accountability, no good."

FAQs for ducts & vents installation and replacement projects in Castle Rock, CO

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.
