Worried your air conditioner is trying to tell you something? It might be. Here are telltale signs indicating it may be time to consider air conditioning installation in your home. A sudden drop in energy efficiency or frequent breakdowns may be sounding the alarm for replacing your old system with a new, efficient Lennox model.

Inadequate cooling

If your air conditioner is no longer able to cool the room or area as effectively, it may be time to consider replacing it.

High energy bills

An inefficient air conditioner can lead to higher energy bills because it’s using more electricity.

Strange noises

If your system is making loud, strange noises, it may indicate a problem that either needs air conditioning repair or replacement.

Excessive moisture

If your air conditioner is producing excess moisture or condensation, it might be time to replace it.

Unpleasant smells

An unpleasant smell coming from your air conditioner is often an indication of a problem and should be addressed quickly.

Poor air quality

If you notice the air in your home has become stuffy or dusty, it may mean that your air conditioner needs to be replaced.

Advanced age

After 10-15 years, most air conditioners—no matter how well you’ve keep up with air conditioning maintenance—may need to be replaced. If your system is approaching this age, it may be time to invest in a new one.

Benefits of Air Conditioning Replacement

  • Improved comfort: a new air conditioner can help keep the temperature in your home comfortable and consistent.
  • Lower energy costs: air conditioning replacement may help reduce your electricity bills.
  • Cleaner air: newer models are compatible with indoor air quality equipment that removes pollutants from the air and improves air quality.
  • Quieter operation: modern air conditioners are much quieter than their predecessors, allowing you to enjoy a peaceful and distraction-free environment.

Great job by all. They were careful of the landscape replacing the A/C unit. Inside the heating system was replaced and the fit and finish was great. Explained the operation of everything. They came back two weeks later and checked out the operation of the systems plus installation. The tech was here over an hour checking out everything. New system is quiet. This is a company that care about its customer. We highly recommend A-1.
