We are a local business here in the Bay Area We do everything from Replacing gas furnaces to instilling new all-electric furnaces A/C change out, mini-split installations, Heat pump systems, and heat pump water heaters. We are always trying to achieve our customer's satisfaction that's our goal!!
"From our first conversation to finishing my Heating project, Comfort Home Heating and Air was full on fabulous. Juan knows his trade very well and led me through my questions and decisions. Once we agreed on the project and date, Comfort Home showed up on time and seemed to use every moment effectively, by being Systematic and organized. They cleaned the area around the Heating and Air unit so it looked better than before. I can tell by looking at the installation that things were done thoughtfully and cleanly. I have worked with many contractors and have never come close to the satisfaction... even pleasure I had with Comfort. I cannot think of anything Comfort Home Heating and Air could have done better. I highly recommend them, if you want the best."

"Tech said that the Freon leaked out and that the compressor burned out because of it. Quoted $4800 to replace compressor and recharge, or $7,000 for a new AC unit. Got a second opinion and hired a handyman. Turns out the breaker was tripped and needed some fiddling with. AC works great now. Can’t believe they were going to lie about what was wrong to replace the whole AC. Just because it was an old unit. Get a second opinion for them if they tell you something similar."

"10/6/2024 - Ongoing Toilet Leak Issue – Unresolved Since February Dear Albert Nahman Plumbing, I hope this message finds you well. I am writing to express my extreme frustration regarding the ongoing toilet leak issue that has yet to be resolved, despite numerous attempts to rectify it. The problem began in February 2024, when my toilet started leaking and refilling its tank every 2 to 4 hours. Since March 18, 2024, I have had five appointments with your team to address this issue. I have paid a total of $545 for a new canister flush valve and a new toilet fill valve, yet the toilet continues to leak exactly the same way it did before. What is particularly disheartening is the lack of communication since August. I have repeatedly tried to reach out via email and phone, but my messages have gone unanswered (August to October). I chose your company based on your good ratings and the assumption that I would receive quality service from a licensed plumber. Unfortunately, my experience has been quite the opposite. I would appreciate a prompt response to this matter and a clear plan for how we can finally resolve the leak. Thank you for your attention to this urgent issue. Sincerely, Andreas"

Central humidifier installations and replacements FAQs
Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.
With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.
It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.
Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.
If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
