According to the Environmental Protection Agency (EPA), geothermal systems are the most energy efficient, environmentally clean, and cost-effective space conditioning systems available today. Simply put, a geothermal system moves the heat from the earth into the building in the winter, and pulls the heat from the building and discharges it into the ground in the summer and/or is used to heat water. An underground series of pipe loops serve as a heat source in the winter and a heat sink in the summer. We will show you how to tap the earth's free underground energy treasure. Call Today!

"Henry was professional and thorough. He went out his was to see that our heat was restored on the coldest day of the year. You can spend a significant amount of money dealing with the big HVAC advertisers in our market but why pay for their ads when you really want competent service? This company provided me everything I expected in a repair."

Ronan, the owner, was super responsive, patient with my questions and concerns. He is not a salesman, he is a Master Plumber, and able to speak intelligently about options and challenges. The quote was well below what the other company told us, so we took a chance with a new company and are super pleased!!

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.
