Frequently Asked Questions

What is a split system HVAC, and is it right for my Cedar Hill home?

A split system is the most common residential HVAC setup — it consists of an outdoor condenser/compressor unit and an indoor air handler or furnace connected by refrigerant lines. It provides both heating and cooling from a single system and is well-suited for most Texas homes. Our team will assess your home’s layout, square footage, and existing ductwork to recommend the right configuration.

How long does a full HVAC installation take?

Most full system replacements and new installations in Cedar Hill are completed in a single day. Our technicians arrive with fully stocked trucks and follow a clean, efficient process from equipment delivery to final testing. We’ll give you a realistic time estimate before the job starts so you can plan accordingly.

When should I replace my HVAC system instead of repairing it?

A system that’s 10 to 15 years old, requiring frequent repairs, or no longer reaching target temperatures efficiently is usually a strong replacement candidate. Upgrading to a modern high-efficiency system can significantly lower your monthly energy bills while improving your home’s comfort. Our technicians will give you an honest breakdown of repair vs. replacement costs so you can make the right call.

Is Ellis Air able to handle both residential and commercial HVAC in the Cedar Hill area?

Yes. Ellis Air services both residential and commercial properties throughout Cedar Hill, Dallas County, and Ellis County. Whether you’re managing a home or a business, our team has the equipment and certifications to handle the job.

Does Ellis Air offer HVAC maintenance plans?

Yes. Our twice-a-year maintenance plan includes two seasonal tune-ups, a 10% discount on all repairs, and a 2-year warranty on completed work. Regular maintenance extends system life, protects your warranty, and catches issues before they become expensive breakdowns. Ask about enrollment when you schedule your next service call.
