Mountain Lands Heating & Air - Lehi's Certified HVAC Services

Common signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your energy bills. If you notice any of these, it's crucial to call a professional. Refrigerant leaks not only reduce cooling but can cause serious damage to the compressor, leading to costly repairs.

In the Lehi area, with our construction, wind, and seasonal changes, we recommend checking your filter monthly and changing it at least every 60-90 days. If you have pets, allergies, or notice more dust in your home, consider changing it every 30-45 days. A clean filter protects your HVAC system, maintains efficiency, and improves the air your family breathes.

Absolutely. A severely clogged filter restricts airflow, causing your furnace to overheat. As a safety measure, the system will shut down to prevent damage—this is a common cause of "no heat" calls in Lehi, especially during peak winter use. Regularly changing your filter is the simplest, most effective way to prevent this inconvenient and avoidable breakdown.
