"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"

"We had a totally broken HVAC system in our 30 year old house. They came in and fixed it in two days. The guys were very friendly and answered our questions. Our original salesperson was knowledgeable and respectful considering the state of our equipment at that time. Now we have heat for the rest of the Winter and AC for next year. Thank you!"

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"Green Core HVAC was awesome to work with! The team did a great job helping us pick the perfect AC unit for our home. They showed up on time, got the new AC installed quickly, and left the place spotless. Our house is cooler and more comfortable than it’s ever been. You can tell these guys really care about doing a great job. I’d 100% recommend Green Core to anyone needing AC work. Super professional, super friendly, and they really know what they’re doing!"

Heating and Air Conditioning questions, answered by experts

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.
