Clutter blocks airflow and prevents your HVAC system from circulating air. Furniture and draperies that block supply grilles cause condensation. All this moisture creates microclimates in your home that welcome and feed mold growth.So throw out things you don’t love or don’t use. Push furniture away from vents and grilles to keep air circulating. On humid, still days, run a couple of fans to keep air moving.Related: How to Get Rid of Stuff and Declutter Your LifeMold problems often emerge during hot, humid summers when you’re tempted to play with the air conditioner.
But set the thermostat too high, and the air conditioner won’t dehumidify your air effectively; set it too low, and you create cold surfaces where water vapor can condense. To prevent moisture problems and maximize energy efficiency, set the thermostat at 78 degrees F.When you open windows and doors, you let air conditioning escape, waste money, and invite humid air into your cooler home. This causes condensation, which mold loves. So keep doors and windows shut when the AC is humming.Also, maintain your home at around 80 degrees when you’re on vacation or at work. Too often, we bump the thermostat up to 85 degrees, or turn off the AC when we’re away. This raises temperature and humidity, which creates the ideal home for mold.Related: How to Use a Programmable Thermostat to Save MoneyMake sure your air-conditioning unit is properly sized for your house. If it’s too small, the unit will run constantly, elevating costs but not the temperature; too big, and the unit will constantly start and stop, which wastes energy, too.
Install an HVAC unit that’s just right. For guidance, call an HVAC professional or consult Energy Star’s square footage/AC capacity chart.An indoor humidity monitor will help you keep track of moisture levels that, ideally, fall between 35% and 50% relative humidity; in very humid climates, at the height of summer, you may have to live with readings closer to 55%.But if you reach 60% relative humidity, it’s time to look for the source of the added moisture; how does central air conditioning unit workabove 70% relative humidity, certain species of mold can begin growing.how often to service hvac unitIndoor humidity monitors start at less than $20; ac unit for central airmore sophisticated models that simultaneously and remotely track several rooms can climb to $200.If you get a high humidity reading of 60% or more, make sure your air conditioner is doing its job.
Inspect the condensate drain pipe (the narrow white pipe sticking out the side) to make sure it’s dripping regularly. If it isn’t, the pipe is blocked and water may be accumulating inside the unit — or on your floor. If you suspect a problem, call your HVAC professional. To prevent blockage and mold buildup, pour a cup of bleach mixed with water down the drain annually.If the air conditioner isn’t the issue, search for standing water or chronic dampness that’s increasing indoor humidity and providing a lovely environment for mold. Check for puddles or dampness around hot water tanks, sump pumps, freezers, refrigerators, basement doors, and windows. Inspect crawl spaces for ground water dampness or foundation leaks.Groundwater seeping into crawl spaces can add gallons of moisture vapor into your house every day. The simplest defense is to cover crawl space floors with a plastic vapor barrier — 6 mil polyethylene (landscapers’ plastic) — that traps moisture in the ground.
If you regularly crawl in your crawl space, use a heavier plastic that won’t rip as easily: Some 20 mil plastic coverings are on the market.A dehumidifier removes excess moisture from the air.You can buy a whole house dehumidifier ($1,100-$1,800) that attaches to your furnace, treats air throughout the house, and connects to a drain so you never have to empty a tank. If you live in a very humid area, a whole-house system is the way to go.If you have occasional bouts of dampness and musty smells, a portable dehumidifier will suffice ($150-$200).Most models have an auto shutoff that keeps the unit from overflowing when the storage tank is full. Some portables have a hose hookup that automatically sends water into a nearby floor drain.If you can’t find the moisture problem on your own, or you aren’t sure how to correct a problem you do find, call a home inspector or indoor air quality consultant. Look for credentials from a respected industry organization, such as the American Society of Home Inspectors or the Indoor Air Quality Association.
A house call will likely run $250 or more. NEW To My Blog? I'm a Realtor, as you probably know, and so of course I think real estate is a great investment.  Until you end up the landlord to whiny renters.  Over the years the Hubs and I have acquired some rental properties plus the Hubs manages some local rental properties for friends and family who live out of state. Most of our renters are nice, quiet people who pay their rent on time and take care of the property.  Most of them have lived in our properties for years.  We love those renters.  It's the occasional annoying, bitching ones that drive me bananas and that is who I am writing about today.  (Before you start arguing with me and each other read this:  If you are a good renter then don't take offense, this post is not about you.  Actually, even if you're a bad renter, don't take offense, because this post is really only about two people specifically and not even a TYPE of renter.) The Hubs is the one who deals with the renters when they have problems and it's probably a good thing, because I would most likely have a bunch of empty rentals.
Here's the deal, it's 7:30 PM right now and the temperature is 105 degrees.  It has been over 100 degrees for something like 15 days now.  We haven't had rain in about a month.  We are drying up and melting all at the same time.  Everyone's air conditioner everywhere is begging for death and my Facebook and Twitter feeds are filled with people lamenting that their air conditioner has passed over to the other side. This week a renter called us up and told us that the air conditioner was not working properly and they were experiencing "dangerous" temperatures in the house.  We got our usual a/c guy over the take a look and he called to let us know that the unit was shot and we'd need to get a new one.  It would take a day.  We asked what the house temperature was since we'd been told it was "dangerous."  He told us it was 80 degrees and holding.  Not so bad when the outside temp is 104.  (We keep our everyday temperature at 78 in our house.  I guess I'm only 2 degrees from dangerous territory.)
The Hubs told the renter we'd have a new unit installed the next day.  The unit was installed two days ago and every day since the renter has called to complain that the house is "hot."  The first day he called we thought there was something wrong with the new unit so we sent the a/c guy back over to check.  He was met at the door by a cold blast of air coming from inside the house.  He told us the renter was trying to cool the house down to 72 degrees. I wanted to say:  Are you fucking kidding me?  There is no way when it is that blazing hot outside that you can cool your house down to 72 degrees!  No wonder my first unit died, you fucking moron, you murdered it!! Tonight when the guy called he indicated that he would like us pay for a bigger unit for the house so that they can live like sides of beef in a meat locker.  The Hubs was so kind and gracious.  He actually listened to him and sympathized with him and tried to find a solution for this guy. When he got off the phone, I said, "Wow.  
You are such a nice landlord.  I would have told him to suck a dick.  A typical air conditioner can only cool a house down by 20 degrees or so.  He should be thrilled his house is 80 degrees!" Today another renter called to tell us her place was too hot too.  She is getting a new unit tomorrow.  She's another one who is trying to keep her house at 72 degrees.  What is the deal with these people?  I would need a sweater in 72 degrees!! Her unit is a bit different and it needed to be special ordered so it took longer than a day.  She blew her cork.  She also showed her true colors when the repairman showed up and he was not as light-skinned as she would have preferred.  That's when I took a closer look at my contract with her and saw that nowhere does it say that the property is "air conditioned."  Maybe she'd prefer for me to send my repairman home and just lower the rent and call it "un-air conditioned?" Yes, I get that I'm a landlord and I'm supposed to fix things when they go wrong and of course we work hard to get things fixed as quickly as possible, but when we're in the middle of a heat wave it's very difficult to get good people to come and fix the a/c.  
There is a queue and sometimes we have relationships with repairmen that allow us to jump the line, but many times we have to wait our turn.  No amount of screaming and cussing me out is going to help.  In fact, it just makes me want to move slower. I also wonder what these people would be doing if they actually owned these houses.  When you own a house and your air conditioner can't keep up with the blistering weather outside there is no one to call and whine to.  There is no one to listen to your complaints and offer to try and help you.  You're on your own. The worst renter who has bitched incessantly about everything from the day she moved in is actually moving out.  She's bought a home and she's ready to take on home ownership.  I cannot wait until this winter when her furnace goes out on the coldest night of the year.  I cannot wait until her washing machine accidentally over flows and floods her house.  I just wish I could be there to see the chaos and watch her meltdown when the repairman tells her it will be a week before he can get to her.
