It is generally recommended that HVAC systems be serviced at least twice a year, preferably before the start of the heating or cooling season. Regular maintenance can help ensure that the system is running efficiently and can prevent breakdowns, which can be costly to repair. Additionally, regular maintenance can improve indoor air quality and reduce energy bills. However, the frequency of service may depend on factors such as the age of the system, its usage, and the manufacturer's recommendations. It's important to consult with a qualified HVAC technician to determine the optimal service schedule for your system.
The lifespan of an HVAC system can vary depending on several factors, including the quality of the system, the manufacturer, the frequency of maintenance, and the climate in which it operates. On average, a well-maintained HVAC system can last between 15 to 25 years. However, if the system is poorly maintained or used frequently, it may have a shorter lifespan. It's important to keep up with regular maintenance to extend the life of the system and to replace the system when necessary to ensure optimal performance and energy efficiency.

Gas furnace flamed out, needed help ASAP
Lady PIlot - Millersville, MD 21108
After reading the online reviews describing the excellent service customers experienced from Bayside Heating and Cooling, I was pleasently pleased and very grateful that Keving was able to come the day I called to troubleshoot my thermostat/ furnace issues. To be concise- his commitment to fixing my problem went above and beyond. His friendly, knowledgeable demeanor gave me confidence that I had truly chosen the exact company to carry out this job. After eight years of taking my heating system for granted I have now decided to begin a bi-yearly inspection by Bayside to maintain the system at optimum level. Thank you Kevin, and Bayside!
