"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"

"Tony was knowledgeable and explained the step by step service to be performed and why it was important to a heating system for efficiency and general maintenance. I thought the price was not inexpensive. However, I chose Ramirex Duct Cleaning due to Tony's presentation. Tony and his 2 assistants were neat, efficient and careful. My 24 year old furnace blade system and 10 vents were cleaned as well as the dryer and vent system within 3 years. Tony took before and after pictures of each phase of the operation which was impressive."

Heating and Air Conditioning FAQs, answered by experts

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.
