How to Decide to Repair or Replace

Repair vs. Replace

Questions you must consider when determining if you should repair or replace your current HVAC system.

Age of Equipment?

Equipment that is 10 years old or older is often expensive to repair, with no guarantees that additional problems are not close behind. However, if the system has been trouble free thus far and looks to be mechanically sound, it may be a good decision to wait on replacement.


Does your equipment need frequent repairs?

Frequent repairs are a sign that your old unit has reached the end of its life and is just worn out. Continuing to pay for more repairs is only prolonging the inevitable. The sooner you replace a unit in this condition, the sooner your energy bills will improve, which can end up paying for the new system and saving you money in the future.


How long will you live in this home?

Will you be moving soon? You may not get your investment price from replacing your system if you plan to move within 1-2 years. However, a major factor in buying a home for a person living in Texas is “How good is the air conditioning unit?” If the system is limping along because the current homeowner didn’t want to spend money, then the potential buyer will require the seller to “drop the price” for the value of a new system. Now, the current homeowner has lost the benefit, (i.e. lower utility bills, more comfortable conditions) of enjoying the new system for the past 1-2 years and doesn’t receive the “asking price” because the home needs a new HVAC system.


Are your energy bills too high?

Your air conditioning system makes up as much as 60% of your utility bill each month. Older, inefficient systems use more electricity to deliver the same comfort level as current high-efficiency units do. It is not uncommon for our customers to report dramatic drops in their energy bills after we install their new system. Although each home is different, 50% reductions in utility bills (from the same time period during the previous year) have been reported.


Are you comfortable with your current equipment?

Are some rooms either too hot or too cold? These kinds of problems are usually the result of an improperly engineered system when the home was built or when the last unit was installed. A well trained technician can diagnose hot/cold spots in your house and determine if the problem is related to the unit’s size (tons), inadequate insulation, improper duct work or some combination of these. One of our Comfort Consultants can provide you a Complete Home Evaluation to make sure these problems are dealt with properly.


Does your home have humidity problems?

Poor equipment operation, inadequate installation, improperly sized unit, and leaky ductwork can all cause the air in your home to be too dry in the winter and too humid in the summer. Again you will want one of our Comfort Consultants to perform a Complete Home Evaluation to determine the cause and eliminate it completely.


Do any family members have allergies, asthma or other air quality health concerns?

The air quality inside most homes is actually worse than outside your home. Indoor Air Quality (IAQ) can be dramatically improved 100% throughout the whole house with today’s high tech IAQ technology and air conditioning products. Does your system have variable airflow? New systems keep the air moving at different speeds, adding comfort and improved humidity control.


Why is my home so dusty?

Leaky ducts can pull particles from your attic and crawl spaces and distribute them throughout your home. Sealing existing ducts or, if the duct work in your home is in poor condition, replacing your ductwork can be beneficial.


When is the best time to buy an air conditioning system?

Before it breaks is the best answer I can give you. Too many times people wait till the system breaks, usually right in the middle of our hot Texas summers. Most reputable companies are very busy during the summer, requiring you to make a quick, impulsive decision that can have lasting consequences on quality and overall costs. Planned replacement of your HVAC equipment allows you to make an educated and informed decision, providing you peace of mind knowing that you have made the best decision possible. And always check for manufacturer and utility rebates before you replace. Equipment manufacturers offer seasonal rebates, as well as most utility companies.
