For 45 years we’ve been making Puget Sound homes the most healthy, energy efficient and comfortable homes in the country. Our experienced team brings decades of expertise installing and maintaining the most innovative and efficient technology. As a Mitsibushi Cooling and Heating Diamond Contractor, Evergreen Home Heating and Energy has some of the world's most efficient and innovative products available.
"We had Evergreen Home Heating and Energy install a new water heater and furnace, and unfortunately, the quality of their work has been disappointing. Recently, I noticed several issues with the intake and exhaust pipes. Several hanger straps attached to the wall are broken, and one of the joints on the water heater exhaust pipe is leaking water. I suspect this leak is caused by the imbalance due to the broken hanger straps. I expected a professional and reliable installation from Evergreen Home Heating and Energy, but these problems indicate a lack of attention to detail and quality. Based on my experience, I cannot recommend Evergreen Home Heating and Energy. If you’re considering them for your home needs, be cautious and perhaps look elsewhere."

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.
