Tim pointed out a few things that needed attention wiht my 9 year old York furnance (capacitor and a full filter on my humidifier). He appeared to have done a thorough check of the unit and did not try to sell me things I did not need. I do have a second system in my home and Tim allowed me...

"I scheduled a tune-up service for my AC for 9-12 o'clock. At 11:35, I called to see if they were still coming, and she tells me 'sorry, the tech is running behind. He will be there closer to 1:00'. I accepted that, then waited until after 1:00 to call them again, only to find out the tech was still an hour away, working on another job. I thought the whole point of a service 'window' was to provide flexibility for the tech in case they get held up. I had to leave my house by 2:30, so I canceled the appointment. I took out an entire day for absolutely nothing."

FAQs for humidifier repair projects in Clayton, MO
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.
