Whether your home just isn’t getting cool enough or you hear strange noises coming from your HVAC system, your air conditioner could be to blame. Recognizing these common signs of trouble can help you identify the problem and know when to call for help with your air conditioning system:

Your air conditioner is making noises.

If your previously quiet home is now full of wheezing, whining or humming, it could be a sign that you need to have your air conditioner repaired. Noises can be the first sign of trouble, and having your unit checked out right away can prevent further damage.

You notice strange odors or excess moisture.

If your home suddenly has a mildew smell or you see condensation or moisture, then your air conditioner could be the issue. A professional can check out your unit to ensure it is working – or find out if it is the source of the moisture.

Any of the above signs is a clear indication that your air conditioner is in trouble; the sooner you call for help, the better. Contact us at Cunningham Associates to take care of your air conditioner so that your home can then be returned to its normal and comfortable state.

What Whole-House Ventilation Can Do for You

Many of today’s homes lack proper ventilation, which can lead to stale and unhealthy air. As a result, some individuals suffer from allergies and other health problems brought on by poor indoor air quality.

Your air conditioner does a great job of cooling air and removing circulating particles, however, alone, it isn’t always enough to renew your home’s air. That’s why you should consider installing a whole-house ventilation system.

A whole-house ventilation system overcomes the lack of proper air circulation experienced by many homeowners. There are three whole-house systems in widespread use, and each of these are described below.

Exhaust Ventilation Systems

An exhaust ventilation system works by using a roof-mounted exhaust fan to suck air from the interior of a home and blow it outside. This causes fresh air to be pulled through the microscopic pores and crevices in the sides of a home.

As a result, air moves across, up and out of a home. Exhaust ventilation systems work well in drier, cooler climates. However, they are not ideal for humid areas where moist air can be pulled through walls, causing condensation inside the insulation and between drywall panels.

Supply Ventilation Systems

Supply ventilation systems work in an opposite manner from exhaust ventilation systems. Instead of pulling air through a roof-mounted vent, supply systems pump air into the home; this  forces air through the walls from the inside to the outside.

Supply systems have some advantages over exhaust systems, such as the ability to filter incoming air through the roof-mounted supply fan. However, during winter, supply systems can create drafty conditions and potentially interfere with indoor heating.

Balanced Ventilation Systems

A balanced whole-house ventilation system is the best solution, since it takes elements from both types of whole-house systems and combines them. A balanced system uses both exhaust and supply fans to provide an even mixing of air inside the home, which can mitigate some of the disadvantages associated with both of the other options.
