FAQ

Why should I have regular (or preventive) maintenance? And how often should I have it performed?
Regularly scheduled preventive maintenance is essential for your heating and cooling equipment. These sensitive systems work hard day-in and day-out to maintain your home climate. Continual operation – as well as frequent starting and stopping – can contribute to increased wear and tear on your home HVAC unit. Regular maintenance is essential for increasing the lifespan of your heating and cooling equipment, and it improves effective performance. 

Regular maintenance inspections can help identify major issues (including leaks, rot, soot, frayed wires, and corrosion) that can contribute to decreased performance and even equipment failure. Regular maintenance may also be required to receive the full benefits of your systems limited warranty. Schedule a preventive maintenance check with Sunny & Cool to ensure your equipment is operating in top condition and to help reduce future issues in your home heating and cooling equipment.
What equipment requires regular (or preventive) maintenance?
You should have your heating and cooling equipment tuned up by a professional annually in both the spring and the fall. If you have an air conditioner and heat pump, your service technician should inspect your fan, compressor, indoor and outdoor coils, and all refrigerant lines.

For homes with boilers and furnaces, inspections should cover ductwork, pipes, dampers, valves, chimneys, registers, radiators, pumps, blowers, oil tanks, fuel lines, and all components of the boiler and furnace themselves. A full check of your systems is key for maintaining their performance in the summer and winter months and for maintaining the complete coverage of your systems' limited warranty.
What type of filter should I use? And how often should I replace it?
While a standard air filter will do the basic work of keeping your ductwork and system clean, it will not improve your home’s indoor air quality. Many homeowners rely on media air cleaners to solve this problem. A media filter is situated between your main duct return and the blower cabinet to improve a standard air filter’s removal of dust and particulate matter by up to seven times. Beyond this, an upgraded pleated media filter can even remove viruses from the filtered air. 

Whatever solution you decide upon, you should always match your air filters to the capacity of your HVAC blower. To ensure optimized performance and air quality, we recommend replacing disposable filters monthly or cleaning reusable filters monthly as well.
What’s wrong with my noisy air conditioner? Can I fix it myself?
First things first, you shouldn’t attempt to fix your noisy air conditioner on your own! Unless you have professional knowledge of HVAC electrical system layouts and the proper meters to test all the working components of your AC, you are putting yourself and your air conditioner at significant risk for harm.
What is the best thermostat setting for summer?
Saving money on your monthly electric bills in the summer is important—so what is the best thermostat setting during the hottest season of the year? We recommend keeping your thermostat set to 72 degrees (at the lowest) with the fan set to AUTO rather than ON.
Why are heat pumps more efficient?
Heat pumps are one of the most energy efficient HVAC systems available on the market because they don’t burn fuel to provide heat. In addition to their high efficiency, they can operate as both a heating and cooling system, thus reducing the number of systems that require maintenance, repairs, and replacements.
