If your AC system is in need of replacement, the national average air conditioner installation costs range from $2,930 to $3,670. Costs can vary greatly depending on whether you are replacing a wall or window unit or a central air system. A central air system is connected to ductwork that runs throughout your house and pumps cooled air into your various rooms via vents and registers. A central air conditioning system is far more costly than wall or window units. Selecting a central AC system that has a high seasonal energy-efficiency ratio (SEER) will likely lower both your carbon footprint and your utility bill. The type of AC system you select, where you live in the country, and the regional costs of HVAC work, duct removal and replacement, and ductwork repairs that are needed are some of the main factors that affect the cost of new air conditioner installation. Here are some examples of average costs for installing forced-air systems.

Inspect your furnace thermostat by first making sure that it’s turned on. Also, ensure that the thermostat switch is turned to “heat” and not “cool”. If your furnace will still not start with the thermostat on, try adjusting the temperature settings to a few degrees higher. Inspect any visible wires for breaks or splits, and make sure your thermostat batteries are not dead. Do not touch any open wires; contact a professional.

A pinging or popping sound coming from the duct work can come from thermal expansion—the ductwork expanding and contracting as it heats and cools.  Or, air blowing past a loose flap of metal can make the sound. Track along the duct runs, listening for the sound. If you locate it, make a small dent in the sheet metal to provide a more rigid surface that’s less likely to move as it heats and cools.

Follow the instructions above under Air Conditioner Not Blowing Air and refer to your owner’s manual.

Many disconnect blocks contain two cartridge fuses. Check them before you proceed with repairs (Photo 3). A blown fuse is a sign of a failing part inside the condensing unit. So don’t just replace it and think you’ve solved the problem. Instead, replace the parts we show here. Then install new fuses and fire up the unit. If it blows again, call a pro—you’ve got more serious issues.

The cost to replace your gas furnace will vary based on the type and size of furnace you select, labor and installation costs, and any repairs your HVAC system may need. Nationally, average HVAC prices for a heating specialist range between $1,800 and $2,500. It’s important to select the right size gas furnace for your heating needs. A furnace that’s too small won’t heat your house properly, while a furnace that’s too large will run inefficiently, cycling on and off and likely breaking down sooner. HVAC specialists calculate your exact heat needs by measuring your home and incorporating variables such as the regional climate and your home’s level of insulation. Retail pricing for gas furnaces can range from $650 up to $3,000 and more. The higher the AFUE (annual fuel utilization efficiency) rating of the furnace, the more efficient it is at turning fuel into heat and the lower your carbon footprint and utility bill will be. HVAC installation costs are often based on an hourly rate and can range from under $50 to over $100 per hour, depending on the company and the furnace being installed. Higher-end furnaces cost more to install because they require added labor and expertise. For a typical installation, it might take two HVAC installation pros one day or less to remove your old furnace and replace it with a new one.
