"TERRIBLE, TERRIIBLE, TERRIBLE!!!! My home warranty company sent Salego to my home due to furnace cycling on/off.(Furnace was still heating house, just took a little longer than normal.) technician arrived and instead of looking for a problem, immediately started changing settings which the furnace had been set to for many years. He Increased high limit shut off temperature, and increased blower to max speed. (Furnace had operated perfectly fine on previous settings for many years.) After making those adjustments, the furnace would not even ignite. (My furnace always ignited prior to technician making those adjustments.) technician never performed any diagnostics or checked functioning of a single sensor. Instead, he looked inside the heat exchanger and said “this furnace is shot, the heat exchanger is cracked.” Technician then began discussing prices of new furnace. Once again, my furnace was heating my home prior to this service call, now technician was leaving and my furnace wouldn’t even ignite. I asked him to make it work again due to me having a 1 year old child in the home and needing heat. Technician refused to make furnace operable because of the risk of carbon monoxide. I explained I have CO detectors which have never detected any CO in the house but he still refused to make my furnace operable. Conclusion: I paid $75 for technician to make my problem worse and completely disable my heat. What a deal, huh? A 2nd opinion revealed heat exchanger is not cracked and my furnace is not “shot.”"

Air Duct Cleaning questions, answered by experts

If you just moved into a new house or found significant mold, dust, or pest remnants in your vents, or you see condensation on your air vents, you can easily find a highly trained pro to do the job correctly by asking a few key questions:

  • Do you have proof of liability insurance?

  • What about worker's compensation insurance?

  • Are you a member of the NADCA?

  • Have you worked on my model of HVAC system before?

  • What is included in your contracted amount?

  • Can you provide local references?

Professionals suggest through ventilation, source removal, or filtration systems.

Finding mold in an HVAC system is never fun, but the good news is you can clean it and send those spores packing. That being said, hiring a helping hand may be necessary to fully remove the mold and prevent regrowth. Professionals use specialized tools and cleaners, such as antimicrobial solutions and HEPA vacuums, to safely remove mold from ducts, coils, and other components. For small amounts of mold, homeowners can clean visible areas using a mix of water and detergent, but they must wear protective gear and avoid spreading spores.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

It can take anywhere from a few days to several weeks to clean smoke damage, depending mostly on the extent of the damage and the method your professional uses. Ozone smoke restoration is a popular option that takes just 24 to 48 hours, but you may need multiple treatments to remove odors. For major house fires, it might be a better option to replace smoke-damaged materials, which could take six to 12 months.
