"Our house is 60 years old. We have lived her 42 years, this the first time we have had the ducts cleaned. The air in the house just seems lighter, the biggest thing is we have a black glass top entertainment center in the den. U could clean and 2 days later it was dirty again. We had this done2 weeks ago, it just now needs cleaning. We are very happy with the results. Would highly recomd it. Also vent centers is a filter company with wonderful filters for your air ducts. Ventcenters.com we put them in all our registers"

Air Conditioning FAQs, answered by experts

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

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.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.
