Frequently Asked Questions About Heating & Air Conditioning

On average, air conditioning units last 12 to 15 years, while heating systems last 20 to 25. If your HVAC systems aren't getting regular maintenance, it's likely they won't last this long. It’s very important to get your systems checked annually.

Generally, furnace systems should be checked in the fall and ACs in the spring. Equipment should be serviced at least once a year for optimal efficiency and longevity.

If your current system is older, you should definitely consider the costs of repair versus the savings of purchasing a new system. Often, repair will ultimately cost more than replacement — especially if your system is older. Older systems tend to use more energy than modern alternatives.

New options can be up to 60% more energy-efficient. If your AC or heater is 10 years or older, you should consider replacing it. Also, consider your comfort level. Are you getting the desired heating or cooling from your system? With our cost-benefit analysis, we’ll advise you on your options with repairing or replacing.

There are many energy-saving options to take advantage of. These include upgrading to a high-efficiency system, installing ceiling fans to change the direction of airflow, closing vents in less-used rooms, adjusting temperatures by just a few degrees while out of the house (up in the summer and down in the winter), changing your air filter regularly, and installing a programmable thermostat.

Tune-ups can ensure that your HVAC systems are working efficiently. A professional will check to make sure the key components of your HVAC system are working properly and make adjustments when needed. Some things we check are carbon monoxide emissions, leaks, unit wiring, and the ignition system.

Dust and debris can disrupt a system’s airflow, so filters should be regularly cleaned on both indoor and outdoor units. Refrigerant levels, coils, and bulb temperatures should also be regularly inspected. Specific to cooling systems, evaporator and condenser coils should be cleaned, as should the blower component. For heating systems, the gas and oil connection should be regularly maintained, as well as the gas pressure and heat exchanger.

Changing filters is absolutely critical. One of the biggest reasons changing filters is significant is because it improves the indoor air quality by keeping your house free of germs and dust. Cleaning the filters also increases the service life of your system while keeping it running at its best. If a filter is left unchanged for a long enough time, so dirt and allergens build up, your system can fail altogether. Another benefit is that you'll ultimately save money and reduce your monthly HVAC bills.

Choosing the right HVAC system for your home is easy when you work with professional technicians. We can discuss your temperature preferences, measure your home size, evaluate your insulation, and talk about other factors before installing a new system.

Choosing the right HVAC system sizing for your home depends on several factors including square footage, insulation, layout, and climate. Using an air conditioner size calculator has many limitations, which is why getting a professional HVAC load calculation is the best way to determine the correctly sized HVAC unit for your space. This is crucial to avoid inefficient operation, high energy bills, and uneven cooling or heating. 

A proper HVAC maintenance schedule recommends servicing your system twice a year—once in spring and again in fall. Following a seasonal HVAC tune-up plan improves energy efficiency, prevents unexpected issues, and extends equipment lifespan. An HVAC maintenance plan is key if you're wondering how often to service HVAC systems for peak performance. 

If you notice uneven temperatures, strange noises, poor airflow, or rising utility bills, these are clear HVAC repair signs. When to call for AC repair often depends on symptoms like frequent cycling or your AC making noise. Furnace issues or other HVAC troubleshooting needs should never be ignored, as they can lead to more extensive repairs. 

A ductless HVAC system, such as a mini-split installation, is ideal for homes without ductwork, finished basements, room additions, or areas with inconsistent temperatures. These ductless air conditioner systems offer zoned cooling and are known for being energy-efficient HVAC solutions that are easy to install. 

The key difference between a heat pump vs HVAC system lies in how they operate. A heat pump provides both heating and cooling using electricity, making it ideal for mild climates. In contrast, a traditional HVAC system typically includes a separate furnace and air conditioner. A properly sized electric heat pump system offers efficient year-round comfort and lower utility costs with professional heat pump installation.
