"I was very impressed with the work done by Hawk Air Duct Cleaining. After a mold remediation, I wanted the ducts cleaned to make sure they were not harboring any spores or toxins from that incident. Hawk was professesional, communicated clearly, and did an excellent job. Their vacuum truck creates a negative pressure in the whole system and then they cleaned each duct individually. They even left the vent covers sparkling."

"I had an issue with my computer where it was opening lots of pop ups, ad bars, and windows with ads for games. I had tried several different programs to try to remove it with no luck. I finally decided to call North Alabama Technical Service to see if I he could help. I was expecting to set up a time for him to look at it but he connected to my computer immediately and within an hour had it fixed and running perfect again. Great service at a great price and I didn't even have to disconnect it and carry it somewhere! Would call again if I have another issue I can't resolve myself."

Air Conditioning FAQs, answered by experts

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

In some cases, yes, portable air conditioners are worth buying. They’re a relatively affordable option for cooling small spaces. (On average, they cost between $100 and $500 per unit.) Plus, they’re easy to set up, and you can move them around to cool various parts of your home as needed. However, they aren’t the most efficient AC option, and they tend to be noisy.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.
