Consumer Comments for 4 Seasons Heating & Air Conditioning

Consumer from PIEDMONT, CA
Apr 19, 2025

4 Seasons installed a mini-split and replaced a ceiling fan in our master bedroom on the third floor. The work was somewhat more involved than anticipated but was done at the quoted price (which was reasonable). The workers were efficient and thorough and kept all areas clean. Very pleased!

Consumer from Redwood City, CA

The only company that willing will work on my in floor furnace from 1947. They can get or fabricate parts to complete the job. Occasionally there is a delay in getting service if they are swamped.

Consumer from Santa Clara, CA
Mar 26, 2023

I had a new furnace and A/C installed in May 2022. As far as I can tell, the work was done properly. However, almost a year later the company has not been on top of getting the required city inspection of the work. There was an unfortunate death of an employee's relative, but still it should not take a year to arrange the city inspection of the work. So, was it done properly? Probably, but the city hasn't inspected the work.

What to Do If You Need HVAC Repairs

If you need repairs, our ratings of local businesses will help you find a good company to perform them.

Choosing New HVAC Equipment and Getting It Installed Properly

How well a new HVAC system performs, and how much it costs, depends heavily on its design and the quality of installation. It’s important to make the right decisions—and there are many to make. You also must make sure to get a fair contract.

HVAC Equipment Features to Consider

If you are installing new equipment, in addition to making choices about energy efficiency, you will need to decide whether to pay extra for various features. Here is a summary of the types of add-ons.

Are Heat Pumps the Future of HVAC?

Improved technology, generous tax credits and rebates, and lower utility bills might have us reconsider how to heat and cool our homes.

Maintaining Your HVAC Equipment

The most important maintenance task for HVAC systems is something you can do yourself—replacing the air filter. Check your filter monthly. When a filter has a matting of dirt—i.e., it’s difficult to see through when you hold it up to a light—it’s time to replace it.

HVAC Maintenance Contracts Are Usually Bad Buys

Rather than paying for individual maintenance visits and repair jobs, you might consider getting a service contract for air-conditioning and/or heating equipment. Many companies try to persuade customers to enter into such contracts.
