"ThermaTek Heating and Air - Jamey Jamrosz, HVAC Specialist/Owner gave me a quote over the phone. I agreed to have him come for any evaluation of my AC. He arrived within 3 hours of my call. After checking everything out, he explained my options and the cost of each. I decided to go with the repair option, which he proceeded to complete the same day. Jamey was fast and personable. I will follow up with him for my HVAC needs for my condo. I will recommend him to my condo neighbors."

Heating and Air Conditioning questions, answered by experts

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.

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.
