Cobex Construction Group is your 5-Star trusted exterior contractor for Roofing , Siding and Windows. We are a local family owned home improvement company with a combined 30 years of experience in home improvement and construction. Our company principle is "people before profit" we believe in the saying “Do it once, Do it right”
"I regret hiring Cobex to install a new roof on my house. They took five months to begin work and took twice as long as expected to complete. We asked the sales crew for custom skylights and to repair dry rot on the architectural details of the house. None of these details were passed to the construction crew and during construction, we were told the custom skylights would not be covered under warranty. It also became apparent that they did not have the expertise to handle the carpentry work for the dry rot repair. I had to manage the project daily to direct the repair work and point out corrections. In the end, we didn't get the skylights we agreed to and the dry rot repair and detail work was subpar. They missed areas of dry rot and used inferior wood. Also, Cobex did not tarp the roof before a predicted rain storm and damage was done to the interior ceiling, walls, furniture and carpet. Five other homes they were working on were also affected. I hired another contractor and did work myself to make repairs they missed since I did not trust Cobex's workmanship. We were given a discount but that did not cover the cost of additional repairs and rainwater damage."

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.
