Services

One HVAC Contractor for Your Whole System

CityLine Air Conditioning holds Texas license TACLB00033708E and runs its vans and technicians from Richardson. We install Amana and Daikin equipment and service most major brands.

Our work covers the whole system. That means the outdoor AC or heat pump and the furnace in the attic. It also means the ductwork between them and the air you breathe indoors. Whatever part of the system is giving you trouble, one call handles it.

Air Conditioning Services

We repair, tune up and replace central air conditioners. When one of our AC technicians arrives, they start inside at the thermostat and ask what you've noticed. Next, they take gauges out to the outdoor unit. Then they tell you what they found and whether it needs a repair or only a tune-up.

If replacement makes more sense, we can replace the whole system or only the failed part, like a coil or condenser. Either way, the new parts come with a 10-year manufacturer warranty.

Heat Pump and Ductless Mini-Split Services

Heat pumps and ductless mini-splits both heat and cool. A heat pump does it for the whole house through your ducts. A mini-split works room by room, with no ductwork needed. We install and repair both, and we keep heat pumps tuned up as well.

Heating and Furnace Services

Our heating work includes furnace repair, maintenance and replacement. Heating season here usually runs from mid-January into early March. That's why November and December are our furnace tune-up and inspection months.

If your furnace needs replacing, ask about Peace of Mind, our 10-year labor warranty add-on. For $1,200, it brings labor coverage on the new system up to 10 years, matching the parts warranty.

Ductwork Services

Every bit of heated and cooled air reaches your rooms through the ducts. In many homes we visit, they haven't been touched in a decade or more. We clean ducts, seal leaking joints, repair damaged runs and install new ductwork. The result is air that reaches the rooms you need it in.

Indoor Air Quality Services

Pollen and dust hang in the air here for most of the year. Many homeowners don't know their heating and cooling system can be upgraded to filter more of it out. We start with an air quality test. Then we recommend only what the results support. That could be a better filter, UV lights, an air purifier, a humidifier or a dehumidifier.
