While a hygrometer is the most accurate tool for measuring humidity levels in the home, you can gauge humidity levels using simpler methods. One way is by observing signs like condensation on windows or feeling excessively sticky or clammy indoors, indicating higher humidity. Another DIY approach involves the “hair method”—aka placing a few strands of human hair in a closed container with salt for several hours. If the hair becomes limp, it's likely due to high humidity. These methods offer rough estimations, but lack the precision of a hygrometer for accurate readings.

Experts suggest your HVAC system should be inspected once per year. If you’re buying a new home, it’s also a good idea to have the house’s HVAC system professionally checked before the final sale. For HVAC systems older than 10 years, it’s recommended they are inspected twice per year. If you suspect a problem, you should schedule an inspection, even if you’ve already had one this year.

Waiving a home inspection could be beneficial if you’re buying a home in a hot location where the seller has many other offers to consider, especially if other buyers are willing to waive the inspection. However, it’s not usually a good idea to waive an inspection, even on new construction. Inspections can identify problems that could cost thousands or even tens of thousands of dollars, so a formal inspection is always worthwhile. If you’re having a new home built, a pre-drywall inspection is often the most valuable, but a final inspection before you close is also a good idea.

Gaps in new construction are common and typically not a cause for concern. New homes experience settling during the first one to two years as the foundation adjusts and building materials acclimate. Monitor gaps during this period and address them once settling stabilizes to avoid repeated repairs.
