"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!!!"

"I recently had a new HVAC system installed by Aireserv, and I couldn't be more pleased with the results. From the beginning, the team was professional, courteous, and informative. They arrived on time and were very thorough in explaining the detailed installation plan, the features of the new system, and how to operate it. The installation went smoothly, and the technicians cleaned the area while working. Once the system was installed, they ran tests to ensure everything was working perfectly and took the time to answer all of my questions. The new HVAC system has been a game-changer in terms of performance. It heats and cools my home more efficiently than my previous unit, and I've noticed a significant improvement in comfort and air quality. The system runs quietly and maintains an even temperature throughout my home. I also appreciate the energy savings I'm already seeing.

"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."

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.
