"Fair service on my furnace. The thing I am concerned is I was overcharged with the Thermostat they installed. I paid $145.00 for a thermostat costing $85.00. I checked price from other businesses to see how much the same Thermostat cost. Also, found out after they left that the name of their business is inscribed in the thermostat they installed. It should even be discounted since they are using the thermostat to advertise their business. This is taking advantage of innocent people like me. Won't use them again."

"Very quick response. Two technicians responded.  A difficult job given limited attic access to furnace. Job completed successfully. Technicians could not have been more polite and accommodating. While I did expect a charge because part had to be replaced, and total job took quite a bit of time, there was no charge as work was accomplished under Comfort warrantee. Highly recommend this business for any heater and/or air conditioning repair/service.

"I first contacted Valley to get a quote on how much it would cost to get air conditioning installed. I live in an older town home that is approximately 1100 sq. ft. They sent someone out to take a look and see what was involved. He was very professional and explained what was involved including getting permits from the city. He quoted the amount and provided me with an invoice. I contacted them 3 months later to say I was ready for the install. The installation turned out to be quite challenging due to the way my home is constructed, but Valley made it work. The service person had to stay a few hours longer but I wasn't charged anything extra for it. They stuck with the amount of the estimate that was quoted. It's only been a couple of months since the install, but I have to say my only complaint at this point is how cold it gets when I turn on the air. But that's a nice problem to have. :)"

FAQs for air conditioning projects in Sunnyvale, CA

A standard blower door test takes between 30 minutes and one hour to complete. The process involves setting up specialized equipment in your doorway, running the fan to create pressure differences, and taking measurements throughout your home. Additional services like thermal imaging or detailed leak detection will extend this timeframe. The technician will also spend time explaining the results and making recommendations based on their findings.

Preparation involves turning off all combustion appliances, such as gas furnaces and water heaters, for safety. Secure all exterior doors and windows, but leave interior doors open to allow airflow throughout the house. Close fireplace dampers and cover any ashes to prevent them from being drawn into living spaces. Clear access to potential inspection areas like attics and crawlspaces, and inform everyone in the household about the test to prevent accidental door openings during the process.

Older homes often benefit most from blower door testing because they have more air leakage points than newer construction. The test can pinpoint specific areas where relatively inexpensive improvements will yield significant energy savings. 

Many homeowners of vintage properties report noticeable reductions in drafts and more consistent indoor temperatures after addressing issues identified during testing. The potential utility savings often recover the testing cost within a reasonable timeframe.

New construction must meet increasingly stringent energy codes that specify maximum allowable air leakage rates. Meeting these standards requires careful attention to air sealing details during construction. 

Success depends largely on properly installing air barriers, thoroughly sealing around penetrations, and quality control throughout the building process. While achieving code compliance is challenging, builders who implement systematic air sealing protocols succeed in meeting required standards.

It's best to schedule a follow-up test after completing all recommended air sealing and insulation work. This allows you to verify the effectiveness of your improvements as a complete package. Allow sufficient time for all sealing materials to cure properly—often a few weeks after completion. The verification test provides documentation of your home's improved performance and confirms you've addressed the issues identified in the initial assessment.
