"Pacific Coast Home Services charged me $450.00 on May 10th to have my Air Conditioner repaired. On July 1st when the heat wave hit San Jose my air conditioner did not work. Pacific Coast did not stand by their GUARANTEE and I had to call another company to do the repairs. Thankfully, they were an honest company and made the repairs. Pacific Coast Home Services consisted of their salesman wanting to sell me a maintenance agreement for $900 ... I should have realized at that point he was not interested in fixing my problem and asked him to leave my house !!! He did remove a few leaves from the air conditioner and clipped a few nips off a bush nearby ... there was no repair done for his billing me $450.00. I am 92 years old and feel this was ELDER ABUSE !!! DO NOT CALL THIS COMPANY!!!"

"Jeff has come to the rescue twice to my new build home. He came the first time in the middle of summer when the a/c would start up. It was just the fan running. He was able to repair the unit same day. Recently, the same thing happened but with our heater. The burners were not lighting up. Apparently the builders never put the cover on and they got clogged with dust and debris. He was able to get our heater working and cannot be more thankful. He was able to fix a couple of things in the attic that the builder just slapped on. I’m sure this system will not stand the test of time, especially here in Vacaville so I’ll trust New age when it’s time to replace this system"

"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"

"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."

"Just had the initial diagnostic visit. I was given terrible news (I'll probably end up getting a new furnace $$$), but the technician Ricky was wonderful. He was extremely polite, professional, and friendly. He did a very thorough inspection and then gave me a very thorough explanation of the problems. This included photos he took on the spot of some internal parts (oil leakage, heavy dust & dirt, stress markings).... at no point did I feel like I couldn't trust what he was telling or showing me. He answered every question I had. He went into the "attic" of my Eichler to check the ductwork (via a 14" hole in the closet ceiling, into space so shallow and tight I have no idea how the ductwork was ever even installed), and came out with photos to show me. The company was easy to work with when I had to change appointments, sent me email and text confirmations of everything, and gave me a day-before reminder of the appointment. I had an 8a- 11a window and received a text at 7:50a letting me know the technician was on his way, with a photo of him included. Perfect, perfect, perfect. The visit was $89 but reduced to $39 because I signed up for the MVP membership: $107 for a year which gets me all kinds of free services plus discounts on everything else. It even includes services on my water heater which they did not install! Additionally, they have some really good guarantees, MVP or not. Before leaving he called the office, explained all he'd found, and handed me the phone to set up an appointment with a "comfort specialist". Ariel (on the phone) was also extremely polite, professional, and friendly. These people are trained right! Or they're hiring very well. So, I will be meeting with someone to discuss repairs vs. replacement options. No repair work has been done yet (although Ricky did do a temporary fix that is allowing me to get some heat), so I can't fully review the company. But thus far I'm 100% pleased. This is probably the best experience I've ever had with any kind of repair technician. I've never used them before and have also never written a review before. The experience was just that good. I'll write another when I've finished with them just to give a full review, but so far perfect!"

A dryer vent allows warm, moist air from inside the clothes dryer unit to escape to the outdoors. Without one, the warm air and moisture remain in your home, leading to mold, rot, and higher cooling bills over time. This project requires cutting a hole in the exterior of your home, so you should hire a professional contractor or carpenter to perform the work.
Use rigid metal when the duct runs behind walls, under floors, or through ceilings—it’s durable and clears lint efficiently. Semi‑rigid metal works well for short, visible sections that need a little flexibility. Your installer will match the material to the layout, but steer clear of flexible foil or vinyl hoses, as they can trap lint and increase the fire risk.
In tight spaces—a compact laundry room, kitchen, or bathroom—a slim or periscope duct lets the dryer sit close to the wall and still vent efficiently. This approach permits the dryer to sit close to the wall while ensuring efficient airflow. Slim vents offer a wide, rectangular design that fits perfectly in confined areas and can be installed vertically, horizontally, or diagonally. If allowed by local codes, surface-mounted ductwork further enhances accessibility and safety.
Plan on hiring a dryer vent cleaning professional to visit your home once a year to keep airflow strong and reduce fire risk. Large households or extra‑long vents may need a check every six months. Regular service sweeps out lint, spots damage early, and helps the dryer run more efficiently.
Qualified professionals for dryer vent installation include HVAC installers who deliver unmatched expertise for safe, secure installations. Experienced handypersons, plumbers, and roofers also perform these projects when the job is simple or when the vent pathway is clearly accessible. An HVAC installer guarantees a proper, code-compliant installation. For complex installations involving concealed ducts or challenging routes, always choose a specialist with a solid track record.
The maximum allowable dryer vent length is set at 25 to 35 feet by local building codes. Any 90-degree turn in the vent layout reduces this maximum by five feet. This exact measurement ensures efficient airflow and minimizes lint buildup, thereby enhancing safety. Adhere to your local code requirements to guarantee a proper and safe installation.
