Is your filter dirty? This can cause a lot of issues. Be sure your filter is clean and doesn’t need replacing. Also, head to your thermostat and check the battery, as well as making sure the setting is clicked to on and positioned to heat. Lastly, check your circuit breakers to make sure one didn’t trip.

Step 1. Go and check the thermostat first. Is it turned on, and to the heat setting?

Step 2. Is the furnace switch set to on?

Step 3. Did your circuit breaker trip? Make sure it’s okay.

Step 4. Check the furnace filter. It can become clogged. If it is dirty, it’s time to get a new one to replace it.

Step 5. Check the furnace’s front panel. Is it closed securely?

Step 6. Is the gas valve in the right, “on” position?

Step 7. Blocked air ducts can cause a problem. Make sure they’re not blocked.

Step 8. Still nothing? It sounds like it’s time to call a professional if the above fixes don’t work.

The cost of furnace repair depends on what the problem is. This can range from $100 to $1200. The average repair cost is usually pretty close to $300. In most cases, people spend between $170 to $500. What you pay completely depends on the type of furnace you have and other factors, like whether the furnace is under warranty. You also have to consider what replacement parts cost along with labor costs.

When replacing central air conditioning, there are a couple of things you need to consider. The price ranges from between $3,700 to $7,000, which includes the unit. This figure is based on information from HomeAdvisor. While this is the typical price, it can vary based on where you reside, which type of system you’re interested in, and the shape of your existing air ducts.

A general rule of thumb is to consider 1 ton of AC for 500 to 600 square feet. But, it’s more complicated than that. The thing is that there are multiple factors that go into the right size unit. It’s important to also consider insulation, ceiling height, climate, windows and doors, and even how many people live in your home. The best thing to do is have a professional HVAC contractor come out and use a Manual J to help you find the correct unit size for your circumstances.

Most air conditioning systems last for about 12-15 years if they were properly installed, and well-maintained. When it comes to heat pumps, consider a 14-year life span. This is when you follow the recommended maintenance. Don’t slack on keeping things maintained, because it extends the life of the unit. Once the unit is over 10 years old, you might want to look into forgoing all the repairs and simply replace it.
