I am a reasonable person and expected to pay something toward the repair, but I have not been contacted by anyone after numerous calls asking to have the repair made.

The repair person found a loose connection which was quickly reconnected. He replaced the filter and checked over the entire system. It was money well spent!

I bought one of the Angie's Big Deals and wow am I glad I did. I had been thinking about having my air conditioner checked out even though there was nothing apparently wrong with it. Every year I turn it to cool and like magic it works. I know that can't go on forever so I was pleased to see...

"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."

Are you looking for Professional Appliance Repair in Seattle, Bellevue, Takoma, Issaquah, Kirkland, Dedmont, Newcastle, and surrounding areas? In this case, you came to the right place! At Professional Appliance Repair we offer expert appliance repair and maintenance services for refrigerators, washing machines, dryers, dishwashers, ranges, ovens stoves, and cooktops, no matter what model number does it have!
"I'd like to express my disappointment with the recent service visit. The technician displayed unprofessional behavior through rude questioning and used inappropriate tools (Cobra Pliers instead of proper hex ratchet or ratchet wrenches) that scratched the burner base. He quoted an additional $250 for cleaning on top of the $99 visit fee, which I had no option but to agree, then failed to fix the issue and recommended replacing the entire assembly. The lack of respect shown toward me as a customer, combined with the use of wrong tools and failure to complete the repair, made this experience not one I would recommend to others."

"It was way too expensive for the work that was performed. They originally said that the pipes leading up to the faucet may need to be replaced and the wall opened up. Previously before engaging them. I asked for a possible quote for how much it would cost and they told me that it was up to the technician. When they came out to do the work that they would determine the amount. I asked the technician how much it would and he told me that it was up to the company to decide for how much the work would cost. When I contacted the company they told me again that it would be up to the technician to determine the how much it would cost by checking the amount of work. I could not get an answer from both of them because they would just keep passing each other on who to ask for the quote. After the project was completed, I was given the bill of about $750+ to replace the faucet, to replace the hoses and the two knobs roughly $350+ each. When I called the company about the price, I was transferred to the dispatchers and was told that I need to talk to the technician for it."

FAQs for humidifier repair projects in Bothell, WA
If your refrigerator needs to be repaired, contact an appliance repair company to diagnose the issue and repair your refrigerator. It’s okay to leave it plugged in and running, but unplug it if it makes unusual noises.
Signs that your refrigerator may need repairs include:
Food items are not being held at the correct temperature (between 35 and 38 degrees Fahrenheit)
The fridge is using too much energy and seems to run all the time
Loud and/or unusual noises
Possible causes include:
A damaged door
Faulty condenser coil
Malfunctioning control board
Contacting an appliance repair professional as soon as possible can help save items in your fridge from spoiling. Common fridge repairs include the compressor, control board, thermostat, defrost motor, coils, and ice maker.
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 to repair an appliance depends on the appliance, make, model, the part that needs repair, and how long it takes to replace or repair a part. The following are the average repair costs for the most common appliances:
Refrigerator: $200–$300
Freezer: $90–$500
Oven, cooktop, range: $100–$500
Microwave: $50–$400
Dishwasher: $160–$300
Garbage disposal: $70–$250
Washing machine: $50–$450
Dryer: $100–$400
Appliance repair contractors may charge $40 to $120 per hour for labor, and most also provide the replacement parts necessary at an additional cost. It’s also important to note that these prices can go up on holidays and emergency fees may apply if you need your appliance fixed immediately.
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.
