"Had them out about 7 months ago to replace insides of my dryer as it was not working. Thought they did the job as our dryer worked. Then two days later the credit card I used to pay them had several unauthorized charges on it. Now 7 months later my dryer needs to be fixed again, with all of the rollers replaced, which is what they said they did 7 months ago. They are crooks. DO NOT USE THIS COMPANY."

You will then have the opportunity to try out the ideal system to make sure it is a good fit with a 100% satisfaction money back guarantee.

Starts at $45/m with security equipment included List of options: Wireless Security: Perimeter protection Motion Glass Break sensor CO detection Smoke/Fire detection Water sensor Medical Pendant Doorbell Camera 4k Outdoor Camera Indoor Camera 24/7 30 day Smart Hard Drive + Cloud Storage Smart Home: Smart Doorlock Nest Thermostat Element Thermostat Garage Controller Wifi Mesh Systems Lighting/Appliance control What sets us apart is the level of service we will provide, the price point, the lifetime warranty on all equipment and the cellular back up meaning most parts of the system will operate without Wi-Fi. (including video clips) Thank you for taking the time to read this, please contact me if you have any questions or if I can help you in anyway.
"Vivint is the worst company I have ever done business with. Having Vivint is a condition on my lease and, if it wasn't, I would quit in a minute. The company is so cheap about replacing malfunctioning equipment. My front door lock doesn't work and I have been working on getting a replacement for over a month. Still no luck. An appointment is not an appointment but I rough guideline to when someone may or may not show up. There are a lot of alarm companies and I could never recommend Vivint."

FAQs for heating and air conditioning service projects in Castro Valley, CA
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
