Air Conditioning FAQ

If you have questions about your AC unit and how to take care of it, read below to learn from the experts at Dana's Air Conditioning We offer service on weekends, and holidays at no extra charge.

We recommend servicing your air conditioner twice a year to maintain efficiency. Factors like location, air quality, and pets may require more frequent maintenance. Regular check-ups help keep your system in top shape and prevent costly repairs.

An AC tune-up typically includes a thorough inspection and cleaning of the air conditioning unit. This involves checking the thermostat for accuracy, replacing the air filter if necessary, ensuring proper refrigerant levels, and examining electrical connections and safety features. It's also important to ensure that the AC unit has enough open space around it for adequate air circulation. Regular maintenance like this helps improve the system's efficiency and can prevent more serious issues from developing.

To check if your air conditioner is working properly, look for consistent cooling, effective humidity control, no unusual noises, stable energy bills, and good air quality. Regular maintenance and timely repairs are key to keeping your system efficient.

Bigger isn't always better for air conditioners. Choosing the right size for your home's cooling needs is crucial. An undersized unit may struggle to cool effectively, while an oversized one can cause humidity problems. Our team can help you select the perfect fit for your comfort and efficiency.

With regular maintenance, most air conditioners last 10-15 years. In South Florida's climate, scheduling maintenance more frequently after the 5-year mark can help extend its life. High-end models may last longer, but consistent care is essential to keep your system running efficiently.

Single-stage air conditioners run at full capacity or not at all, which can lead to less efficiency. Two-stage units, however, have two settings—full capacity and a reduced level (about 70%)—allowing for better energy efficiency and humidity control. They provide enhanced comfort and are more efficient overall.

Humidity influences the perceived temperature in a room; for instance, 70 degrees in Arizona feels different from 70 degrees in Florida. ​ An air conditioner not only cools the air but also removes humidity, enhancing its efficiency. Therefore, it's expected that a two-stage AC, which operates longer at a reduced power level, will extract more humidity from your home than a single-stage unit. A variable-speed system will be even more effective in this regard. ​ Pairing a whole home dehumidifier with an air conditioner is often recommended to boost efficiency, regardless of the system type. This should be considered when choosing between different systems. Discussing dehumidifiers with your HVAC contractor is advisable, especially considering your home's average relative humidity and the specific air conditioning system you choose. ​ A variable-speed system also circulates air more often by running longer, which helps remove more particulates, improving air quality. However, this may mean more frequent filter maintenance, among other considerations your HVAC provider may deem important.

Installing a time delay on your air conditioning system offers several benefits: 1. Prevents Short Cycling: Stops the compressor from turning on and off too frequently, which can cause overheating and damage. 2.Reduces Wear and Tear: Limits the high current drawn at each start, allowing the compressor's windings to cool between cycles. 3. Protects Against Power Fluctuations: Prevents the compressor from restarting too soon after a power outage, allowing the refrigerant to stabilize and reducing motor stress. 4. Adds Redundancy: Serves as a safeguard if the thermostat's built-in delay malfunctions, offering additional protection. In summary, a time delay helps maintain your AC system's efficiency and longevity by preventing premature compressor wear and potential damage.

If you're using an older mechanical thermostat, it's wise to install a delay timer on your condenser. Incorporating an extra time delay to your compressor, even if your thermostat includes one, offers multiple advantages: Many new systems already incorporate a compressor time delay relay as part of its control system, but some do not. During a repair, adding a time delay relay to the compressor’s control system can save thousands on future repairs. ​ 1. Prevents Short Cycling: It stops the compressor from turning on and off too frequently, which can cause overheating and damage. ​ 2. Reduces Wear and Tear: It mitigates stress on the compressor’s windings by limiting the high current drawn at each start, allowing the windings to cool between cycles. ​ 3. Protects Against Power Fluctuations: It prevents the compressor from restarting too soon after a power outage, allowing the refrigerant to stabilize and reducing motor stress. ​ 4. Adds Redundancy: It serves as a safeguard if the thermostat's built-in delay malfunctions, offering additional protection. ​ Installing a time delay relay in the control system can prevent the compressor from short cycling. After shutdown, the compressor is paused for three to five minutes before it can restart, helping the windings to cool down.
