Heating and Air Conditioning questions, answered by experts

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.
