"Perfect Star sent a technician out to assess my HVAC issue. and it turned out to be my ducts had been torn apart by critters getting into my crawl space and trying to nest. I got a crawl space cleanup crew to address that problem but Martin (my HVAC technician) told me about an air purifier that could be installed to my HVAC units. He installed those for me right away and they are working great."

"Needed gas fireplace maintenance. They came by, diagnosed the problem quickly, told me the part to order and said that I could actually fix it myself when I get it - no charge! But when I received the part from Amazon I asked them to come back to install it. Their office is only about a mile from my house in Fairfield, but the day they came they were working in Berkeley - obviously very popular! They showed up, put the part in, did a little troubleshooting, and we had a working fireplace again! They were very nice and professional and inexpensive - I would definitely hire them again for any HVAC problem. Lucky to have them so close."

"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."

"Air Concept quoted me a very reasonable price on cleaning 2 wall furnaces at a duplex recently. I had one other quote before for an outrageous price. Charles, the owner, was very honest about the work that involve- only vacuuming off the dust inside the furnace basically. The two employees were punctual and courteous. I thought they would include vacuuming or wiping down the furnace cover as part of the cleaning. They did after I asked about it, so they did one cover at the 2nd unit. That's why I took off half a star. Other than that, I am satisfied with their work and would recommend their service again."

Heating and Air Conditioning FAQs, answered by experts

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.
