"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

Heating and Air Conditioning questions, answered by experts

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.
