"It's been a couple months since Zach with McDonald's Home Solutions analyzed our air-conditioning needs and had Potts and Vince install the Mitsubishi heat pump and duct work. They were amazing and very hard working. The system is working great and makes a huge difference in the comfort level of our house. It's extremely quiet. It operates like a whisper and we hardly know it's on other than the house is cooler. I checked the energy use of the system against our solar panel productions and it hardly makes a difference. It's amazingly efficient. I strongly recommend anyone considering installation of an HVAC system to use McDonald's Home Solutions. They're the best."

"Starting with JP the senior technician, the inspection and documentation of existing conditions was thorough, knowledgeable, and complete. Moore recommended the replacement system that would be more durable and require lower maintenance over time, and wrote a detailed proposal with a floor plan documentation. We were given financing options at the time of signing the agreement, as well. The team- five technicians!- were properly suited with protective gear and followed COVID protocols at all times on our property, inside and out. They wore shoe protectors while inside, kept us fully appraised at every task (all interior registers replaced in 11 rooms), and were extremely respectful of our space, privacy, pets, and kept noise and speaking to low levels. (our extremely friendly indoor cat got lots of attention from the team!) The work required three days to fully replace all ductwork in a two-story home with attic and crawl space, and Paul the team leader would check in with us each morning with a briefing of each days' activities. The entire team was constantly in learning mode, with the senior technicians mentoring and teaching the younger team members, which greatly impressed me. They finished on time and without any delay or disruption; they cleaned each work area and removed all debris, packaging, and the old system. We've owned this house for 20 years, had many repairs and replacements, and Moore has raised the bar so far for quality and value. While they were the middle bid in terms of overall cost, we believe we received higher value that even the highest bid. I can strongly recommend them to anyone planning repair work on their existing system, new installations, or maintenance. After getting few responses from HVAC contractors working in new homes in Sonoma County, we were pleased to know that Moore specializes in existing homes and responded to our online request within minutes. I'd be happy to share my experience in person, if required. Martin Waldron Sebastopol, CA"

"Jim's Air Systems had the best value for my dollar. They supplied me with better equipment than they quoted for the same price. They completed the entire installation in about five hours. They protected my floors with tarps and were very careful to protect my walls as they moved equipment in and out. Josh, the son of the original Jim, was on the job working with the other two installers. They performed above my expectations. They left my home and yard as clean as if they had never been there. The new furnace is wonderful and is already saving me money on my P.G. & E. bill. I would recommend Jim's Air Systems unconditionally to anyone in need of a new furnace and AC system. This is a family business that has been supplying and installing systems since 1976. They take personal pride in doing an excellent job. They did not sell me anything that I did not need and provided me with a much cleaner and easier-to-service installation than my existing system. They are the best!"

Air Conditioning questions, answered by experts

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
