The Goodman GXV9S is a premium, high-efficiency variable-speed air conditioner designed to deliver quieter operation, consistent indoor temperatures, and improved comfort throughout the cooling season.
Unlike conventional single-stage air conditioners that operate at full capacity whenever cooling is needed, the GXV9S uses inverter-driven technology to adjust its cooling output based on your home's needs. This allows the system to operate at lower speeds during lighter cooling demands, helping maintain more consistent temperatures while reducing unnecessary energy consumption.
Its variable-speed operation can also improve indoor humidity control when paired with properly matched indoor equipment, helping your home feel more comfortable during warm weather.
The GXV9S features environmentally lower-impact R-32 refrigerant compared with older R-410A systems, a compact side-discharge cabinet, and advanced communicating controls designed to optimize system performance.
At In Demand Plumbing, Heating & Air, we install Goodman variable-speed cooling systems for homeowners who want premium comfort, quieter operation, and long-term energy efficiency.
The result: more precise cooling, fewer noticeable temperature swings, and a more comfortable home.

Your questions
HVAC Maintenance & Tune-Ups questions.
Does a tune-up include every repair the system might need?
No. Maintenance and repairs are different scopes. Findings that require additional work should be discussed before that work proceeds.
How often should HVAC maintenance be scheduled?
Maintenance frequency depends on the equipment and manufacturer guidance. Heating and cooling systems are commonly checked seasonally.
Does maintenance include repairs?
No. Maintenance and repair are separate scopes. Any repair needs identified during the visit should be discussed before additional work proceeds.
Can maintenance prevent every HVAC breakdown?
No. Maintenance can help identify conditions needing attention, but it cannot prevent every future equipment failure.
Should I mention existing comfort problems during maintenance?
Yes. Tell the technician about unusual sounds, cycling, airflow or comfort changes so those symptoms can be considered during the visit.
Do you serve homes outside Oakley?
Yes. Explore our service areas or contact our team about your property address.

I had an excellent experience with In Demand Plumbing, Heating & Air, especially Ezequiel and Donald. Ezequiel was professional, patient, knowledgeable and reassuring from the moment he arrived. I was dealing with a very stressful water-damage situation, and he took the time to listen as I explained what I had observed. He quickly identified the source of the problem—a broken toilet supply line upstairs that had caused significant water damage. He clearly explained what happened, completed the repair, restored the water and thoroughly tested everything to make sure there were no additional leaks. I especially appreciated Ezequiel’s communication and the time he took to discuss prevention, including recommending a Moen Flo system to help detect and mitigate potential water issues in the future. Donald, the HVAC technician, was also extremely helpful. He checked the HVAC system while they were there at no additional charge and made such a positive impression that I scheduled an appointment with him for next week to follow up on the system. Excellent customer service all around. Both Ezequiel and Donald made a stressful situation much easier to manage through their professionalism, knowledge and kindness. I would absolutely recommend In Demand Plumbing, Heating & Air.

Ben deserves 10 stars, but You only have room for 5. He was so good to take time to explain every thing He did so now I have a good idea of how the heater and A.C. work. He also knows how to explain things so a 92 year old can understand just how things work. He deserves a BIG RAISE.

Of course, when it's one of the hottest days of the year, the A/C will act up. I called and Jasmin got Don (Don the HVAC guy) out here first thing the next morning. We have used In Demand years ago for our plumbing needs and now will use them for our HVAC needs. Don was very thorough and explained everything that he did to get our archaic A/C going again. It is a gift to find a company that does business "old school". Showing up on time, being knowledgeable and answering questions as well as a positive attitude. Don is the type of service person you want in your home.
