Meet the Expert: Micah Sherman, Frontdoor Virtual HVAC Expert
A Frontdoor HVAC Virtual Expert , Micah Sherman has more than 10 years ’ experience in the HVAC field . He grew up in the trades with his dad and started working on HVAC units as a teen . He has a bass heat to aid homeowners solve their mending needs safely .

We added an additional two bedrooms to our 1968 house. Should we buy a bigger furnace to help push the air?—Frank, via Facebook
Micah ’s advice : You have a lot of selection here . Without knowing the accurate size of your home , the rooms you added , or the sizing of your organisation , I ca n’t give you the “ right ” answer forwhat sizing furnace you involve . But there are some thing you could consider when making your decision .
First off , just increasing the size of your furnace wo n’t solve your issuance without adjusting your ductwork as well . It does n’t count how big your furnace is , if your ductwork is n’t large enough to handle the amount of breeze that a larger system can campaign out , then there is n’t any economic value in increasing the size of your furnace .
The right way to do this is to have a Manual J test do on your home by a master . This is a series of computation performed on your domicile to find out the HVAC needs of your home – it will tell you the tunnage required to the right way heat up and cool your house . Any qualified HVAC technician should be capable of perform one of these test .
You could add some canal work to those bedrooms , and that will convey air into those elbow room . However , bear in mind that there is only so much air available to be used . Just like a pie , the more pieces you write out , the less there is per piece . So , the more tune that we divide in your home , the less each way will get . Doing this may lick your consequence , but it could also negatively affect every other way in the house .
Another option would be installing ductless mini - split system in those room . Doing this would hit the need to correct the size of it of your furnace or ductwork , since each way would have its own mini - AC / oestrus system of rules . Many home around the world expend these , and they ’ve convey quite popular here in the United States as well .
I’m 57 and I live in a 1955 Rambler-style home. Growing up I never heard of duct cleaning. However, I have seen ads for it over the past few years. Is it actually necessary, or is it just a way to make a buck?—Mike, via Facebook
Micah ’s advice : Whether or not duct cleansing is necessary heavily depends on what case of duct you have , how dirty they are , and whether they ’ve ever been pick before .
If you have a flexible duct or duct board , Iwould not recommend take a canal cleaningperformed . The hazard of ripping or tear the duct themselves is comparatively high-pitched , which would cause more problems . Also , channel panel has a protective facing built into it , which keeps the fiberglass out of the air current . If the tools used in the duct clean rips this line drive , it expose the fiberglass beneath it which allow it to enter your home .
If the ductwork is dirty enough to guarantee a channel cleaning , it may be worthwhile to consider replacing the ductwork altogether . you could houseclean these types of duct , but there is hazard involved .
If you have metallic element ductwork , ensure that the company doing the duct cleaning has the right instrument . When a proper duct cleansing is done , they will foreshorten a hole into the supply and return to hook up the vacuum and will also brush the runs down towards the system . They will also have a vacuum cleaner truck as well , not a shop vac on wheels .
If you ’re having a duct cleanup performed , TheNational Air Duct Cleaners Association ( NADCA)recommends cleaning your air ducts every three to five years . However , I would urge hold back your epithelial duct before getting them cleaned . Every 3 to 5 geezerhood is credibly too frequent in my opinion . By keeping your HVAC arrangement and home clean , you drastically slenderize the need for canal cleaning . workaday criminal maintenance on your HVAC system helps keep the air in your home clean , thus keeping the canal clean .
In the meantime , you’re able to remove the gentle wind vents yourself and pick them , as well as the duct run as far as you’re able to reach with a shop vac . The duct are ordinarily dirtiest near the vents anyway .
What is the best way to insulate an existing crawl space? I know insulating it will help reduce heating bills but I don’t want to have problems with moisture build-up and mold.—Shawne, via the newsletter
Micah ’s advice : You’re right , having your menage well insulated will decidedly avail reduce your heating system bills . The best way toseal a Australian crawl spaceis to use a vaporization barrier and spray foam . You require to avoid fibreglass insularity . The primary goal here is to avoid wet in your crawl space — we want to do everything we can to avoid mold development .
Spray foam insulant and inflexible foam insulating material are highly resistant to moisture and can effectively varnish gaps , which creates a barrier against humidity and air leak , which is key to avoiding modeling development . And always install a vapor barrier alongside the insulation to further prevent moisture .
You also necessitate to ensure the level itself is dry . It does n’t matter what you do , if there ’s stick out weewee , you ’re in trouble . So before insulate the crawl place , remove any excess water , and then isolate . This might call for add together a drain if you have water frequently ooze into your crawl distance surface area .
