"I contacted Citywide for a new roof quote. They promptly returned my call and set up an appointment. The next day I received a call to reschedule and we agreed on a new day. That day no one showed up and after a 90min wait I called. They said they thought the appointment was for the next day, so I agreed to meeting them the following morning. Again on the next morning no phone call and they were a no show. I would give them less than a 1 if it were possible. Beware of a company that treats you that way prior to having your money, who knows how they will treat you after they get your money."

"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."

"I highly recommend Providence Water Heaters! Long story short: my water heater tank was leaking, needed to be replaced, but was in a super inaccessible area (climb over a 3.5 ft. concrete wall in the basement, squeeze through a tiny square hole in the structural support beams, duck under the HVAC system, and there is the water tank, stuck in the corner). I had multiple companies come out to do assessments, give estimates, etc., and I am really happy I found and chose Providence. Anthony was very calm and respectful, was able to provide an accurate estimate from photos I sent, and stood by the estimate provided with no surprise or additional costs. He is super knowledgeable about the products and I felt very comfortable with him. He installed a Navien Tankless water heater and was even able/willing to cut up the old tank so we could remove it! He pretty much had to do all this while sitting on the ledge, since there is not even enough head space to stand up. NOT easy! Anyways, I am very impressed with the high level of workmanship and customer service. They arrived on time, got right to work, left the area looking cleaner than it was when they arrived, and took time to explain all the components of the heater to me. If you are looking for a drama-free, most-excellent water heater installation experience, call Providence. You will not be disappointed. Thank you, Anthony and Jeremy!"

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.
