Maintaining your HVAC system is essential to keep it working at its best for years. HVAC components are built to last for a certain period, and if you’ve owned your home for a long time, you might need replacement parts. You might notice an uneven air temperature distribution, odd noises, or a rise in your energy bill. These are all signs that your HVAC system needs servicing.

Air conditioner

How often is air conditioning service necessary for your home? Most air conditioning systems need assistance at least once a year, but they can last longer with regular servicing. During service, your HVAC technician will clean, inspect, and lubricate your air conditioner’s components and recommend necessary preventative maintenance. The technician will also ask you about any problems that you may have with your unit. Some HVAC service companies offer maintenance contracts where you agree to pay a certain amount each year to receive specialized service. Maintenance contracts include twice-yearly inspections, discounted prices on many parts and accessories, and priority service in the event of an emergency.

The frequency of air conditioning service depends on several factors, including the amount of use your air conditioner gets. If you use your air conditioner almost daily, you may want to get it serviced for a year thrice. However, if you use it only during the summer, you may only need service once a year. If you use your air conditioner in the summer months, you may only need it once a year.

Heat pump

Performing preventive heat pump maintenance twice yearly will ensure your system operates at peak performance and efficiency. By scheduling maintenance simultaneously as you would your car’s oil change, you will avoid future problems and increase efficiency. Heat pumps are expensive and require regular maintenance to stay in good working condition. If you don’t do preventive care, you risk spending more money on repairs in the future. To avoid costly repairs, schedule maintenance twice a year.

The first time you should schedule service for your heat pump is before the first winter. A technician will test the refrigerant and inspect for leaks. He will also oil the motors and inspect the electric terminals. Finally, he will measure airflow through the evaporator coil. During these checks, the technician will also ensure the thermostat is functioning correctly. Depending on your brand of heat pump, it may be a good idea to schedule the first service for a year.


You might be wondering how often furnace service is necessary. However, many factors determine how frequently a furnace needs assistance. Generally speaking, you should have your furnace serviced twice a year – once in the fall and once in the spring. This will help ensure that your furnace works efficiently and won’t break down unexpectedly. Additionally, furnace service will help maintain indoor air quality and minimize health risks.

The most common reason furnaces need service is that various components can malfunction and stop working correctly. Without regular maintenance, your furnace will cease to produce adequate heat and may suddenly break down. Moreover, an unserviced furnace is a health risk, as it can cause carbon monoxide leaks. This colorless gas is hazardous and can cause dizziness, nausea, and headaches. In severe cases, exposure to carbon monoxide can even cause death. Each year, approximately 500 people die from carbon monoxide exposure, and 15,000 visits the hospital. If your furnace fails to meet these standards, it can be red-tagged.

Air filter

If you own a home or business, you must know how often your HVAC service will change your air filter. The average replacement interval is 90 days; for a 1″ filter, this time is between two and three months. This period is six to nine months or a year for higher-end filter cabinets. However, the recommended change interval may differ to your home’s use and environmental conditions.

While most HVAC services and manufacturers recommend changing your air filter every three months, the recommended replacement interval may vary based on your location, pets, and the system age. A single-person household without pets should change the filter every two to three months. This frequency may be as much as nine to 12 months for homes with multiple pets. However, a household with several children or pets will probably need to change its filter more often.
