Heating and Air Conditioning questions, answered by experts

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.
