When it comes to indoor humidity levels, everyone has their own preference for what feels most comfortable. Generally, a relative humidity level from 35-50 percent is optimal for comfort — not to mention preventing the growth of microorganisms.
Ideal Indoor Relative Humidity Levels by Outdoor Temperature
Depending on personal preferences, the most comfortable indoor humidity level will vary from one household to the next. The following temperatures will give you a general idea of where to keep your indoor relative humidity levels:
• For outdoor temperatures over 50 degrees Fahrenheit, indoor humidity levels shouldn’t exceed 50 percent.
• For outdoor temperatures over 20 degrees, indoor humidity levels shouldn’t exceed 40 percent.
• For outdoor temperatures between 10-20 degrees, indoor humidity levels shouldn’t exceed 35 percent.
• For outdoor temperatures between 0-10 degrees, indoor humidity levels shouldn’t exceed 30 percent.

With temperatures dropping, your air conditioner is likely the last thing on your mind. What many homeowners don’t know is that fall is an ideal time to purchase a new air conditioning system. Below are a few advantages to buying a new air conditioner now instead of waiting until next cooling season, along with tips for protecting your unit at winter approaches.
Avoid installation delays.
The average lifespan for an air conditioning system is approximately 15 years, although it can vary based on usage, maintenance, and environmental factors. If your current air conditioner is nearing or past this mark, you should probably expect to replace your unit in the next few years, if not sooner. Purchasing a new system now instead of waiting will prepare you for next cooling season, and set you up for lower cooling bills.
When you buy an air conditioner in the summer months, you may … Continue reading
The concept of a “preseason” can be misleading.
Preseasons are, more often than not, a ploy by the air-conditioning industry utilized as a means for giving their technicians something to do during the slow periods during the year. And, while it’s not necessarily a bad thing to get ahead of the game — especially at a discount — the outdoor temperatures prior to the season may be outside the parameters needed to accurately check the refrigerant charge in your air-conditioner.
If it’s too cool outside and there is no load “cool inside” your house, the saturation temperature may be too low and the load on the equipment too low to accurately check your refrigerant charge. If the system doesn’t have a history of refrigerant leaks, then a glance may be adequate and you may also be able to include a furnace/heat pump maintenance thanks to the mild … Continue reading
Keeping cooling costs manageable during the dog days of summer can be a challenge. Here are a few tips to keep your checking account from feeling the heat.
Change the filter often.
Very few duct systems are air tight. The increased resistance caused by a dirty filter can make your air-conditioner pull in more air through any cracks and crevices in the return air duct system. If your return is in the attic, that means it’s pulling in extremely hot air.
Keep your condenser coil clean.
The condenser coil outside is where your air-conditioner gets rid of the heat it absorbed inside of the home. Having your unit washed regularly increases the efficiency of your air-conditioner. Also, keep shrubs, grass and leaves away from the outdoor unit.
Reroute your dryer vent.
You can’t fix stupid—but you can reroute it. If your dryer vent is close to or blowing … Continue reading
