Reviews of local pros in South San Francisco, California

First time I made a purchase here. I was looking for mini split line sets, but a particular kind. Uv rated, 1/2" and US manufactured, etc. They didn't have what I needed in stock, But Edwin said he can get it pretty quick for a job I'm getting ready for. Instead of choosing to get me off the phone, he gave me options. Within a few days they had the line sets, and they followed up a few times with a status.
Edwin was friendly, helpful, knowledgeable and followed through!
I don't know why they have a 3.8 rating, they are 5 Star in my book!! Thx again guys!

Best place for find any equipment parts of any brands.

Johnstone has some of the best customer service, always willing to help you find what you need and have a great stock of parts. They take The extra time to try and get you the parts you need. I highly recommend any Johnstone location for your HVAC needs.

When you walk into an HVAC specialty store, you don’t always know exactly which part you need. And this is the place where true professionals work — sometimes they understand the equipment even better than the technician. They will always help you, quickly find the right parts, and make the whole process easy.

These guys are truly on the customer’s side. Fantastic place! I definitely recommend it to everyone in San Francisco. Throughout all my years of experience — this is the one spot where you really feel supported with a professional approach. ⭐️

The guy Mike that works their is a rude dirt bag

Great Service, great selection, great prices & great location.

If you are a professional I think this place is fine and they are friendly and helpful. Nobody seemed rude to me. In general this place seems to have a more standoffish policy though, with it's proximity to the city proper I could definitely imagine some not cool people from some large city building running in there last minute for things. If you have a question and time give a call to one of the many other locations.

The two brothers that own this company were helpful and honest. I would recommend them highly.

Annuzzi Heating has saved my bacon a number of times now when my furnace decides to stop working and every time they’re incredibly friendly, professional, thorough, and economical. They’ve never tried to upsell me on unnecessary replacements like some of their competitors and instead charge reasonable prices for very quality service.

Honest and dependable! They were half the price of Smith Brothers Appliance Repair who had told me I needed a new control board on my furnace. The Annuzzi brothers informed me that the control board was fine and they fixed my furnace for 1/10 of the price! I'll never use anyone else but Annuzzi!

Came and estimated in 2 days. Sent out good old Mookie. Was ready to install just a few days later but needed to operate on my schedule and they accommodated me,. They set up an abatement company who also responded quickly. They showed up early for every appointment. The installer and helper were professional. overall a wonderful experience. Pros!
