When it comes to cheeseburgers, paychecks and defensive tackles, bigger is better. But, for HVAC equipment, that’s not always the case. As we’ve touched on in the past, the HVAC system has become a problem source for home efficiency, and incorrect equipment size is a problem with consequences that, perhaps, are not being adequately communicated. Here are five reasons that oversized equipment is no good: 1. Dollars & Cents Oversized equipment has a higher initial cost and costs more to operate. That’s because the system runs in short bursts, which is about as inefficient as the rush hour stop-and-go routine is on your car’s fuel mileage. Longer run times reduce cycle losses and bolster efficiency. It’s also just plain hard on your stuff. An oversized compressor is destined for a short life. 2. Comfort Oversized equipment causes temperature swings. Shorter cycles leave your system playing catch-up—particularly along the perimeter of… Continue reading

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. • For outdoor temperatures between -10-0 degrees, indoor humidity levels shouldn’t… Continue reading

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
