They were friendly, efficient and professional in all respects. Same is true for the estimator who came in advance to assess, explain the job and options for choices. Will use Cardinal for other jobs if needed and recommend to others."

"I had an incredibly disappointing experience with Adams Electric, and I feel compelled to share my story so others can be aware. Over the past few months, Adams Electric has failed to complete electrical work that was promised, left my home in disarray, and charged outrageous fees for unresolved issues—including a $540 bill for a toilet that still doesn’t work after three visits. I personally went to their office in tears, asking for help, and my concerns were completely ignored. I have sent multiple requests for resolution, yet I have received no accountability or action from their leadership. As a company that claims to be faith-based and community-driven, their lack of integrity is deeply disappointing. I will be pursuing every possible avenue to get the resolution I deserve, including reporting them to consumer protection agencies and escalating this issue publicly if needed. I sincerely hope Adams Electric chooses to do the right thing and take responsibility for their actions."

Heating and air conditioning services FAQs

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified 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

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.

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.
