"I had a very positive experience with NRG during the sales process: the people I spoke to were knowledgeable, easy to talk to, and quick to follow up with answers to my questions. That changed as soon as we signed the contract and paid our deposit. Communication became sporadic at best, with each step of the process taking much longer--in some cases many months longer--than what I was told during the sales process. To be fair, there were external factors that contributed to the delays. Our project involves installing new roofing, and apparently several roofing contractors are still backed up after the winter storms in early 2023. But that doesn't explain or excuse the near-total lack of communication or the apparent lack of interest in moving our project forward. It has consistently been a struggle to get even the most basic details from NRG, and I've had to follow up every few weeks just to see if anyone is still working on our project. I can't speak to the quality of their work because no work has been done, or even scheduled, more than seven months after signing. I strongly recommend against working with NRG."

"Come on time and gave me several quotes on couple brand of furnace and size of furnaces. I picked one and work completed in one day on scheduled date. Furnace works well and very satisfied. One issue with company is that it didn't do a home audit to determine the right size fit for the house. I did research and was able to determine one size up was appropriate for my house. Company just wanted to use the same size without asking if I was happy with it. I'm so happy to have upgraded."

FAQs for heating and air conditioning service projects in Discovery Bay, 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.
