"We went with Greenwood because we heard that they would take care of us, even though they were more expensive. We had a great experience with the first walkthrough with a knowledgable expert, but every interaction since has been poor. We had several issues with the installation; they had to come back several times. Five years later, the water pump with the furnace broke and they take care of it, but it costs $900. They take care of us, but continue to be expensive. I highly recommend avoiding this company and finding a business that knows what their doing and where all technicians care about the customer."

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

It doesn’t matter if you live in a small apartment that needs a new HEPA filter or a large business with a long list of Seattle or Bellevue heating and air conditioning needs. Just give us a call, and we’ll be happy to help.

"I won't call any other heating or AC experts ever again. Twice now, I've had incomparable experiences. I had another highly reputed company come diagnose my failed furnace and provide an estimate, but AirPros' price for the same part and repair was much more reasonable and furnace repairs are not cheap, so the difference mattered significantly. AirPros also treated me like family. Go with this family business, you will be happy."

"Replace old broken aluminum windows and patio doors in a house built in the 1980s. Worked with Greg Serna(sales), John Lewis(Installation Lead) and Randy(Lead installer). I liked that Greg's sales presentation was informative and no pressure and listened to what I wanted. I had 5 companies coming out to do the bid and choose Washington Energy partially because how Greg represented his company. Greg has also been responsive and communicative throughout the process when I have questions/issues. From signing the contract to the actual installation date took about 3 month; it was more than the 6 to 8 weeks window I was told. Contract was signed in late April and installation didn't happen until late July. I think Summer is just a busy time for them and I understand so it's not a big deal. Overall, I am happy with the installation process. Randy and his crew were professional and overall did a good job. They sent couple more folks out on day 2 and day 3 of installation period to make sure the job gets done on time as promised to me. I did notice couple issues after installation that I have filed a ticket with Washington Energy Service. They responded and said they ordered the parts and will come out and address them at same time. It does take them awhile to get the parts; it has been a month. Hopefully, they'll be able to come out and address those issues soon. The replacement windows are vinyl and I do notice a huge difference in insulation. The only feedback I have on those windows is the manufacture could improve on those screens. They get bend out of alignment pretty easily. The installer had to fix a few of them. I also wish the mechanism to open/close the patio screen door is more user friendly or easier to use. Overall, I am still happy with these windows."

FAQs for heating and air conditioning service projects in Sultan, WA

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.
