If it is less than 10 years old and the repair cost is less than half the price of a new unit, then repairing may be the better option. However, if your unit is over 15 years old, requires frequent repairs, or isn’t keeping your home comfortable, replacing it with a new energy-efficient model can save you money in the long run.
Common indicators include warm air blowing from vents, weak airflow, frequent cycling, high humidity levels inside, water leaks around the unit, and unusual noises. If you notice any of these signs, it’s time to schedule a service call.
It’s recommended to have your HVAC equipment serviced at least once a year. Ideally, schedule maintenance twice a year, once in spring and once in fall, to ensure optimal performance.
Ductless mini-split ACs are ideal for homes without existing ductwork, room additions, or areas that require individualized temperature control. They offer energy efficiency and flexibility in installation.
Heat pumps provide both heating and cooling, making them versatile for year-round comfort. They are energy-efficient and can reduce your carbon footprint. However, their efficiency can decrease in extremely cold temperatures, so it’s essential to consider your local climate.
Signs include frequent repairs, increasing energy bills, uneven heating, strange noises, and the furnace being over 15 years old. If you experience these issues, it might be time to consider a replacement.
Yes, by incorporating air purifiers, humidifiers, dehumidifiers, and ensuring regular maintenance of your HVAC system, you can significantly enhance your home’s indoor air quality.
First, check your thermostat settings and replace any dirty filters. If the problem persists, it could be due to issues like refrigerant leaks, compressor problems, or ductwork obstructions. It’s best to contact a professional technician to diagnose and fix the issue.
