Evaporator Coil Service, Installation, And Replacement

Dependable evaporator coil replacements in Spring & the Greater Houston Area.

Losing the ability to cool your home during a hot, Texas summer is simply unacceptable for most homeowners. One of the most important elements of your home's AC system is the evaporator coil, and once it develops a problem, the entire system is compromised. The most common problem with an evaporator coil is leaking of refrigerant as a result of corrosion. Lack of maintenance can be another issue resulting in drain backups and water damage to home. Annual maintenance inspections and cleanings will help to reduce and prevent evaporator failures.

Some of the signs of evaporator coil trouble include:

  • Lukewarm air coming from your vents

  • Uneven temperatures inside your home

  • High humidity levels inside the house

  • A/C system is freezing up

  • The A/C is cycling on and off with no change in temperature

If the evaporator coil is dirty or damaged, it won't be able to do its job properly and your AC system won't work the way it should. Sometimes, all it takes is a good cleaning to get it working smoothly once again. In other cases replacement may be needed.

Evaporator types and applications

Slab Coil

There are a quit a few things to consider in terms of replacement of an evaporator coil. System installations vary quite a bit with home construction as to location and type. If your air handling system is located in your attic as most are in the Houston area it will be installed as a vertical or horizontal installation meaning that the air flow through the system is being delivered either vertically or horizontally. Evaporators are available as a dedicated horizontal design in both slab and box coil design applications. While slab coils are only suitable for horizontal installations, box coils are available for both horizontal and vertical applications. We have found that horizontal system installations with slab coils are longer lasting and have fewer repair issues over time than the other alternatives I.E. vertical and horizontal box coil installations.

Box Coil

Horizontal box coils are installed in a great number of homes in our area as they will typically require less attic space for the installation and can be installed in tighter spaces. We have found that these installations develop refrigerant leaks at a substantially faster rate than their slab coil counterpart installation. Cleaning of these coils requires a complete removal and reinstallation and in most cases is cost prohibitive. Air flow through these coils is also compromised with a higher resistance to air flow or static pressure drop because of their size constraints. It is typically more work to install a slab coil vs box coil if space is limited but the benefits of longer lasting and less repair problems makes it well worth the extra expense.

Vertical to horizontal System conversions

Vertical air conditiioning system installations in attics has become common practice in our area by homebuilders. This practice is done to lower the upfront cost of the typical air conditioning installation. with no regard for the cost of premature evaporator failure and damage to electrical components in the furnace from drain leakage over time. We have seen systems that should have lasted 10-15 years with minimal problems being replaced prematurely due to large repair expenses and reliability issues. The good news is that these issues can be corrected in most cases with professional conversion of the installation to horizontal with a slab evaporator coil.
