Why Heating Installation in Mission Is Mostly a Heat Pump Question
In most of the country, heating drives the whole HVAC decision. In Mission it is the smaller half. Winter lows are mild, the cold nights are few, and the cooling load is many times the heating load. For that reason most replacements in the Valley are a combined system, where a heat pump or an air handler with a heat source takes care of both seasons in one unit.
A heat pump moves heat instead of making it, which makes it efficient in our climate, where outside air rarely gets cold enough to hurt it. A gas furnace paired with a separate AC costs more up front and makes sense in some homes, particularly where gas service already runs to the house. We walk through the tradeoffs for your situation instead of defaulting to one.
Sizing Heat Is Different From Sizing Cooling
A common mistake is to buy a large amount of heat because the number looks reassuring. Oversized electric strip heat costs more to run and does not make the house feel any warmer on a mild night. We size the heating side from the same load calculation as the cooling, so the system matches the house instead of the nameplate on whatever it replaces.
Ductwork matters here too. Heat is delivered through the same ducts as cool air. Leaks in the attic lose heat as well as cold, and a house with poor ducts feels uneven no matter how good the new equipment is. We inspect the ducts before we quote.
What Happens When You Replace Both
Because the Valley's HVAC systems are usually combined, a heating replacement often means a full system replacement. If your outdoor unit and air handler are both old, replacing one and keeping the other is usually false economy. The matched pair works better and carries a single warranty. If only the heating element has failed in an otherwise healthy system, we say so and fix that part instead of selling you a new unit.
Installations come with a one year labor and ten year parts warranty. Our contractor license is TACLA35238R, and installation is done by licensed technicians.
Timing Your Installation
Heating installations are easiest in the shoulder months, from late September through early November, before the first cold fronts and before Winter Texans arrive. Installing in January means working around a cold house and a busy schedule. If you know your heater is on its last legs, a fall appointment is the cheaper and calmer way to handle it.

Mission Heating Installation FAQs
Does Cool Aid install heating systems in Mission?
Yes. We install heat pumps, furnaces and combined systems for Mission homes, sized to the house.
Do I need a heat pump or a furnace in the Valley?
Most Valley homes do well with a heat pump because winters are mild and one unit covers heating and cooling. A furnace can make sense where gas service is already in place. We explain the tradeoffs for your house.
Should I replace the heater and the AC together?
If both are old, usually yes. Matched equipment performs better, and one installation visit costs less than two. If only one part has failed, we tell you and repair it.
How long does a heating installation take?
It depends on the system and the ductwork. A straightforward swap can take a day. We give you the expected timeline with the quote.
What warranty comes with a new heating installation?
One year on labor and ten years on parts for new installations. Keep the equipment manufacturer's paperwork with it.
