Heating and cooling units feature moving parts and airflow, so you’ll get a little noise when the equipment is working. Some factors like performance (peak and low) and age also impact noise levels. If you hear strange clicking and grinding noises, call an expert to examine the cause.

The recommended approach is to upgrade to a proper-size HVAC unit with a good to excellent energy-efficiency rating. You can also perform routine maintenance and invest in a programmable thermostat to ensure your units are running only when necessary. Other options include maintaining insulation to prevent leaks.

Water leaks can stem from various issues, including clogged or cracked HVAC drain lines. Pools of water around the unit may also indicate issues with the collector box, evaporator or the heat exchanger. If you notice water leaks and pools, call a professional HVAC contractor promptly to investigate and fix the issue before the unit suffers further damage.

You should schedule at least two HVAC maintenance services per year as a rule of thumb; one for the heating unit and another for the ac. If you have a new unit, follow the manufacturer’s recommendations. You can also schedule pre/post season service or if you suspect something.

You can replace your HVAC unit if you need an upgrade to a more energy-efficient model. Systems 15 years or older also need an upgrade as they’re likely inefficient for current demands. A replacement is due if your unit requires constant repairs and doesn’t provide the required comfort.

Each HVAC service is unique, but you shouldn’t worry about intense preparations. Simply hire a reputable HVAC company and schedule inspections. Your contractor will inform you about necessary preparations, which may involve moving business fixtures and furniture around to create clearance space for the HVAC team.
