The verb ser (soy) cannot be used with a gerund; you must use estar (estoy).

Calefacción is feminine, so the correct article is la.
Estoy revisando la calefacción y aire y acondicionado.
Both nouns need the article el; dropping it changes the meaning and sounds unnatural.

Cultural Tip
In many Spanish‑speaking countries heating (calefacción) is less common than in colder European regions, so you’ll hear it more in places with central heating or in winter‑time contexts. Air‑conditioning (aire acondicionado) is ubiquitous in hot climates, especially in Mexico, Spain’s southern regions, and Central America. When speaking to someone from a tropical area, you might hear more emphasis on the air‑conditioning part of the sentence.
