{ "item_title" : "Practical HVAC", "item_author" : [" Charles F. Nehme "], "item_description" : "HVAC (Heating, Ventilation, and Air Conditioning) is a system of technology used to maintain comfortable temperatures and air quality in a given environment. It is essential for the health and comfort of people in a variety of settings, including homes, businesses, and factories, as well as in public buildings such as schools and hospitals. To ensure the most efficient and cost-effective operation, proper maintenance of HVAC systems is a must. The most basic maintenance task is to regularly change the air filters in the system. Dirty air filters can restrict the airflow and reduce the efficiency of the system, leading to higher energy costs. Additionally, dirty air filters can lead to the accumulation of dust, dirt, and other particles in the system, which can contribute to poor indoor air quality. Regularly checking and replacing the system's filters is just the beginning when it comes to HVAC maintenance. Other important tasks include inspecting the system for any leaks or broken components, cleaning the coils and condenser, and examining the system's controls and safety features. It is also important to have a professional inspect the system at least once a year. A professional can correctly diagnose any problems and recommend the necessary repairs or replacements. Additionally, they will be able to identify any potential problems or areas of concern that should be addressed in the future. Overall, proper maintenance of an HVAC system is essential to ensure its efficient and cost-effective operation. Regular maintenance can help to extend the life of the system, reduce energy costs, and improve the air quality in the environment.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/856/627/9798566273976_b.jpg", "price_data" : { "retail_price" : "35.00", "online_price" : "35.00", "our_price" : "35.00", "club_price" : "35.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
