This contractor stands miles above the rest, is fair and honest, and believes his customers deserve to get value for their money. Top Notch!"

"We’ve had Twin Tiers Electric at our home more than a half dozen times over the last few years. Beyond knowledgeable and skilled workmanship they provide great communication, flexible scheduling, and on time arrival. They minimized the impact their work had in our home and left our home as they found it (maybe better?). They also offered suggestions for alternatives to the work we had asked for safety or to prevent problems in the future. What more could we ask for? But where they really shined was one occasion where we had a so-called lost neutral…a situation in which the voltage at an outlet can be very low to twice the normal 120 volts. We damaged a few appliances before we knew something was wonky. We were lucky we didn’t suffer any injury or cause a fire. The folks from Twin Tiers came out immediately. First they located the source of the problem as the underground cable between our house and the connection with the power company. They arranged for a generator to provide minimal power to our home to keep our refrigerators and water well pump running so we could remain in our home during the repair. So thoughtful! They had to excavate a trench, lay replacement conduit and cable, and backfill. Throughout the work they handled all the communication with the power company to disconnect us from the grid, inspect the work, and reconnect us. Finally they provided the necessary documentation for our insurance claim. They were at our house for over a week from dawn to dusk even through a holiday weekend. What a great work ethic! The service from Twin Tiers is everything we could expect and so much more!"

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.
