We recommend full replacement simultaneously because these units were designed to work together to cool and heat your home properly. If you have a mismatched unit, it won’t work as efficiently so you won’t gain the maximum energy efficiency that you were expecting.
We help you select the model based on the size of your home and level of comfort and efficiency you desire. We perform a detailed load calculation based on your square footage and how much space the unit will need to heat or cool. But it’s not just the size; we also look at the orientation of your home and how much sun it gets, as well as how it is constructed before recommending your new equipment.
Well, it depends. We look at the efficiency of the cooling system by talking with you about the Seasonal Energy Efficiency Ratio (SEER) number. There is also a Heating Season Performance Factor (HSPF) number. We then consider the size of your home, along with discussing your budget, to determine the best fit. There are also add on features to improve your indoor air quality such as home de/humidification and air scrubber systems that are particularly important in Texas.
This is extremely important to the proper functioning of your HVAC system. The contractor not only picks the system with you, but is absolutely critical to the proper installation of the unit. This partnership will last years – they will need to back up their warranty program and will also come out twice a year to do maintenance on the unit. The contractor should have a state license and be well respected. Ask about warranties and guarantees on their work.
