Q: How often should evaporator coils be cleaned?

• <div><p>Your evaporator coils should be cleaned at least <b>once per year</b>. However, the frequency of cleaning depends on your air conditioning system age and performance. If your system is old, keeps breaking down, or continues to underperform, you should have your evaporator coils cleaned twice per season. </p><p>Your home&rsquo;s location also plays a central role. For example, if you live in climates with a lot of moisture, humidity, wind, dirt, or dust, you&rsquo;ll likely need to have your coils cleaned more than once yearly. </p></div>

Q: How do I get rid of mold in my furnace?

• <div><p>Before you start removing mold, turn off the furnace. Clean away any visible mold from accessible areas using a mixture of water and mild detergent. Change air filters and check for moisture sources like leaks. If the problem persists or it's widespread, hire a local HVAC company for professional cleaning.</p></div>

"very poor work quality, I had to have them come back 3 times after the initial installation to repair damages and fix the shoddy workmanship to get the roof right and it still hasn't passed Inspection. On top of that on three other occasions they were scheduled to be there and they just didnt show up at all. They left trash in my yard and in my driveway causing a flat tire on my car due to nails left all over the driveway. I even found missing shingles on a newly installed roof, how does that happen? I also found out after the fact they were TWICE as expensive as their competitors. I called 3 different contractors after getting their final bill and found this out. Twice the price for shoddy work? I'm just glad I was able to get up on the roof and check the quality of the work and demand they corrected it. My recommendation, hire someone else. There are so many other capable company's out there. You dont need to waste your time with this one. It's not worth it."
