We just bought a great house with character (yes, a bit older of a house)…now what?

sold home

I interviewed Eric Metzger, owner of “Fixit Once Repairs” – they do everything from home remodels to cleaning gutters and painting houses.  I asked Eric a variety  of questions on the step after the BIG STEP – buying a slightly older home.  What are some important aspects to consider in a “mature home” to ensure you get the most out of your new investment.  Read on to hear what Eric had to say!

What are some of the key factors to think about after buying an older home?

First, you should think about these before you buy the home. After you buy, it’s too late. Would you buy a used car without having a trusted auto mechanic inspect it and take it for a test drive?

Get an inspection done by a referred home inspection company (find a certified home inspector on HelpHive) other than your realtor’s.  Then work with a referred licensed contractor/handyman to determine what needs to be repaired based on the inspection.  For certain items, inspectors are forced to document as protection for both themselves and their insurance!  Everything else on the report will be cosmetic or safety issues that need to be taken care of, or might need to be done to secure financing. These costs can be negotiated as part of the purchase of the home – have some or all of the work completed before closing depending on who’s paying for the work.

What areas should I check first to ensure I’m not going to run into any problems?

Your inspector will cover the major ones in the report.   Structural, electrical, plumbing, moisture damage, evidence of pest infestation or damage caused from pests and/or wood destroying organisms, drainage, roofing, heating/cooling, and anything else visible during that inspection that is notable..

How can I determine if I have wiring issues aside from waiting for something to break?

This goes back to the inspection.   “Fixit Once Repairs” did a complete gut and rebuild of a home in Everett, due to an overloaded circuit in the garage.  The breaker didn’t trip causing a fire that did $115,000 worth of damage and took two months to complete. After gutting the home, the only items left were the exterior wall studs, siding, roof trusses and the sheathing on top of the trusses. All windows, doors, wiring, drywall, flooring, roof, insulation, cabinetry, fixtures, etc. were damaged from water and smoke. Electricity can be your friend if handled correctly and safely. It can cause lots of damage or worse if not respected.

How can I determine if I have plumbing issues aside from waiting for something to break?home-inspection

The inspection should identify any current issues. Once you own the home, inspect or have someone inspect all areas in the home where plumbing is accessible and visible, including attics, crawlspaces, and the garage. Where pipe, etc. run through walls, look for evidence of staining or water damage/leaks. Quarterly inspections by the homeowner and a yearly complete inspection is what Eric normally recommends.

What about insulation, windows and the furnace?  How do I ensure I’m going to be okay through the winter?

Insulation:

Age of the home will most likely determine the R value of the insulation in the walls of the home unless it has had extensive remodeling done. The higher the R value number, the better the resistance to allowing heat or cold into the home. The parts of the home that are accessible, such as crawl spaces and attics, may have been upgraded. Eric recommends R38 or higher in attics and R21 for walls/crawlspaces.  Eric recommends having non-insulated areas dealt with right away to conserve energy and reduce costs. Some insulation is better than none. Older homes that have not been upgraded could potentially have minimal or no insulation in the attic or crawl, and as little as R7 in the walls if any.  A home built in 1972, for example, was built with R7 in the walls and R13 in the attic. Current code is R21 for walls and R38 for attics.

Windows:

Vinyl or wood framed windows are better than aluminum because they don’t radiate the outside temperatures (heat/cold), like aluminum framed windows do. Dual pane (two sheets of glass with an air space in between) windows are better than single pane windows for insulation value as well as sound dampening. On new windows, look for a Low E rating (indicates a low energy rating which is good). If you don’t know if the windows in a home are dual pane or not, take a lighter or match and put it next to the window. If you see a reflection in the second pane, it is a dual pane window.

HVAC:

Furnaces or HVAC/heat pumps should have filters cleaned at least monthly and a maintenance service done by a qualified technician annually. A well maintained system will save you in the long run on both energy costs and repair bills. Dirt and dust is not the friend of an HVAC system or furnace.  Just like changing the oil and filters in your car, you need to change and/or clean the filters in your HVAC system.  There are many safety related items involving HVAC systems that could be dangerous or even fatal. If your home did not have the manuals for your system, check for a sticker on your system for the company/model/serial numbers and contact the company to request a copy.

The house has a basement.  What type of issues should I be prepared for or look for?

Moisture/water leaking through the walls or floor. If the exterior walls were not treated with a sealant or that sealant has deteriorated with age, the walls could start to have water leaking into the basement. If the foundation drainage system is damaged, clogged, or non existent, water could be standing underground against the wall of the basement and will eventually find a way in.  Basements inherently tend to be damp and moist and therefore you need to inspect for mold issues caused by lack of air flow and moisture. There is quite a bit of evidence on health issues caused by mold, so basement inspections should be taken seriously.

The Top 5 Air Conditioner Brands

Tuesday, June 30th, 2009

A common question at this time of year: “Boy it’s hot!  Maybe we should get an air conditioner.  But which one is right for me? And who can I hire to install it?

Buying a new air conditioner can be quite confusing, not to mention finding a qualified HVAC contractor who you can trust to install the system. I’ve heard all the horror stories from home owners who weren’t happy with the system they purchased and had installed. The top 10 complaints:

  1. It doesn’t cool my home properly
  2. It’s way too noisy – I can’t sleep with that thing on!
  3. The guy who installed it didn’t answer my questions and tracked dirt on my carpet
  4. It leaked water on my garage floor
  5. It broke down after one year
  6. I’m freezing downstairs and way too hot upstairs
  7. My electric bill has gone way up!
  8. The contractor won’t return my phone calls
  9. The company that installed it went out of business
  10. It broke on the hottest day of the year

I’ve been installing and servicing air conditioners and heat pumps for 10 years and have heard it all.  Here’s my run down of the top 5 air conditioner brands:

  1. Lennox: Starting at the top, Lennox has been around the longest and are the efficiency leaders – the other guys watch and learn from them.  Dave Lennox holds the patent for the heat exchanger system that has saved people money over the last century.  It’s a very reliable and a nice looking unit sitting next to your house.
  2. Rheem: Rheem is the next company on my list – I enjoy installing their equipment. They have a small foot print for their units, which makes the ease and cost of installation significantly lower than other brands. Rheem has also been in business for over 80 years, so I like their longevity.
  3. Trane: This is a good piece of equipment that uses the latest in new technology for their air conditioners. As sometimes happens, their strength is also a weakness and has therefore put them lower on my list. The very technology that makes them cutting edge has resulted in a rash of circuit board failures and recalls. That’s a major problem when you sell the most expensive air conditioner on the market. However, they still have a solid product, which puts them in the middle of my list.
  4. Carrier: Here’s another brand that’s been around a long time and has a pretty good track record. Their downfall is similar to Trane. They had major warranty complaints (calls from customers to come back and fix something within the first few years of the warranty period) and recalls on their heat exchangers for 90% of their furnaces. They’ve also had circuit board problems.
  5. American Standard: They have great ratings on their equipment and air conditioners. They are manufactured by the same company as Trane so you are basically buying the same product as a Trane. I’m rating them lower because they are positioned as a generic brand so any heating company can install their product. This can be the worst thing to happen – a quality product not properly installed.

ht_pumpBut not to fear, you can be happier than this little guy IF you choose the right equipment AND contractor.

Start with some research as a followup to my list above – you’ll be looking at your needs and your budget. Then get 3 estimates from reputable companies. Homeowners either don’t get enough estimates or (believe it or not) get TOO MANY estimates and end up more confused than when they started. So, if you’re planning on purchasing an Air Conditioner this summer, get started today – find 3 quality HVAC contractors online or via referrals and get those appointments and quotes moving forward.  And stay tuned – I’ll be doing a follow-up post on what to look for and how to select a good contractor to do the work!

Summer Heat & Pollen Won’t be a Problem This Year at This House

Monday, June 22nd, 2009

It may not be June 21 yet but Summer is definitely here! A friend recently wrote me extolling the heat pump they installed last summer as doing the job of temperature control better than expected as we experience record dry weather and more than a hint of the heat to come. They’re looking forward to a hot summer – and a cool house. The reduction in fuel bills is a benefit as well. Their two regrets are that they didn’t get the heat pump until August last year (miserable July, great September) and that they missed the tax credit offered this year for the same unit. “Minor regrets true, but I’m glad for the comfort in our home these days as our hybrid system now delivers great temperature control and amazingly clean air as well.”

How is the Air in the House Cleaner You Ask?

Well, they had an EAC (electronic air cleaner) installed on the furnace when the heat pump was put in and the airsneeze quality and reduction of pollen and dust in the house is a terrific benefit. Like many people, my friends have allergic reactions to pollen, bacteria and dust mites. Allergies including hay fever and asthma affect 41 million Americans or about one out of six people. This month here in the Pacific Northwest many are being affected by tree pollen, including maples, alders and the cottonwood cotton floating through the air like snow, reminding us to keep allergy meds stocked up. It’s a blessing to have a set of filters capturing the bulk of the pollen and dust in the house and providing a much healthier indoor breathing experience. The Honeywell EAC is “an advanced and easy-to-use, whole-house solution that traps and filters up to 98% of pollutants from the air passing through your heating and cooling system. This advanced air cleaner captures microscopic impurities like dust, smoke and smog particles in addition to larger particles like mold spores and cat dander. It works by placing an electric charge on airborne particles, and then collecting the charged pollutants like a magnet.  Plus, you can say goodbye to monthly filter replacements by simply washing the air cleaner cells in your dishwasher or sink.”That was the sales pitch, and they are sure glad the HVAC company suggested it to them. My friend gladly admits to being part of the 81% of people using EACs who say they have found “significant” relief from having cleaner air in the home. The unit wasn’t expensive and the filters are easy to clean, they were advised to simply run them through the dishwasher.

How do I Clean My Electronic Air Cleaner Filter Cells?

The EAC filters are two large metal boxes (cells) that come out of the front of the unit and have handles to carry them like a couple of brief cases. The toughest part of getting them out is climbing the ladder to reach them (theirs is installed about 3 feet above the furnace, yours will depend on your system needs).They are multilevels of honeycombed filtering metal sheets and are washed down with hot water in the laundry room sink then run through the dishwasher all by themselves about once every 3 months – a bit more often now in the pollen season. HoneywHoneywell EAC unitell recommends consulting the manufacturer of your dishwasher before you attempt to wash the electronic cells – always a good idea. The only recommended washing methods for Electronic Air Cleaner cells are with soaps that are safe for use on aluminum, such as automatic dishwasher detergents. Set four mugs or glasses upside-down to rest the cells on top of. This protects the cells from the dishwasher spikes that may break ionizing wires, and bend collector plates. Never allow the cells to go through the drying cycle. This will “bake on” any materials that were not removed during the wash cycle, my friend says she opens the dishwasher door after the wash and lets them air dry on the racks. If you don’t let them air dry then be careful when removing cells after washing, the cells may be hot, and sharp edges may cause cuts. After washing the cells, take a clean cloth and gently wipe down the ionizing wires. Then slide them back into the EAC unit.

Many folks say their filter cells come out of the EAC nearly black with dust, pollen and other pollutants and go back in sparkling clean, ready to keep the air in their home cleaner and purer no matter what is floating in the atmosphere outside. Of course having the entire heating system kept cleaner and in better working order by having less dust and gunk in the works is a great benefit as well – and not one to be sneezed at.

Improve Your Home’s Energy Efficiency

Tuesday, December 30th, 2008

Where heat escapes from the average home

Replace the incandescent light bulbs with CFL’s – check…done.

Now what?  Many homeowners are asking exactly that question – as we learn and hear more about global climate change, an increasingly important question for many of us is what else can I do to help?  How can I reduce my carbon footprint?  What can I do to live a more sustainable lifestyle?  This week I discussed some potential answers to these questions with Sloan Ritchie, owner of Cascade Built, a green real estate developer here in Seattle.

There are a number of lifestyle and product choices you can make to help out – however, some are more available than others and some may be cost prohibitive at the current time; who ran out and bought the new Tesla all electric (and very expensive) roadster for Christmas?.  And we all won’t be moving into LEED rated homes anytime soon.  LEED rated homes are a rounding error in terms of market availability and these high efficiency, environmentally friendly dwellings carry a premium price tag (although that’s changing).

Having said all of that, you can still help out in your 1992 built, 2000 sq foot <fill in house type>.  Two words – energy efficiency.  Or more specifically heating efficiency.  Did you know that in the average home 50% of the utility/energy usage is for heating?  If you’re going to expend energy to heat the air in your home, you don’t want that same air to immediately find it’s way to the outside (and possibly cold) world.  I learned a new building term this week (thanks Sloan) – ACH or “air changes per hour”.  It’s a volumetric measure of how much air is replaced in your house in a single hour, presumably air from the outside.  A tightly built home has an ACH rating of .25 – .35.  An average house built today has an ACH in the 1.4 – 1.8 range.  An older, more “loose” house comes in around 2.5 or greater.  So, a tightly built (or updated) home, which by the way is a key element in LEED rated homes, makes better use of the energy expended by keeping much of that warm air in the house – which means using less energy to heat – which means you’re doing more than CFLs.

So for those of us that make up the majority of the homeowners and live in an average or older home, how can we improve our ACH?  Well, here’s a quick hit list to get you started:

  1. “air sealing” – the idea is to plug, fill or otherwise block pathways for the air to the outside world – under each faceplate for switches, electrical outlets, phone and cable jacks, install a foam gasket (watch a very short video here) to help prevent air from escaping
  2. While you’ve got the faceplates for various switches and outlets off, have a look to see if you’ve got gaps between the electric box receptacle and the framing.  If so, either caulk (if it’s a small gap) or pack with foam for larger gaps
  3. Make sure you’re windows are well caulked and that the caulk isn’t deteriorating; re-apply caulking as necessary
  4. Check the weather stripping on all exterior doors; if it’s either non-existent or deteriorating, replace it
  5. Take a quick look in crawl spaces, attics and any other non-heated spaces where you might have pipes – find the ones carrying hot water and insulate them.
  6. Make sure to change your furnace’s filter at least twice a year – similar to dryer vent cleaning, the more flow you have through your filters the more efficiently your furnace will run
  7. Next to heating, refrigerators are next in line for improvements in efficiency (and thus savings on the energy use front) – to help the refrigerator be more efficient, simply vacuum the front grill at the bottom of your refrigerator on a regular basis; you guessed it – more flow of air = better efficiency

All of these tips should be doable in a weekend after a trip to your favorite hardware store…  If you’re up for the next level of effort (and potentially investment), here are few more things to consider:

  • how energy efficient are your windows or doors?  Are there more efficient or performant windows available?
  • what about the level of insulation you’ve got in your walls and attic?  Although the builder of your house likely applied what was required at the time, it may be inadequate today, especially if you have an older house
  • Moisture prevention is another key aspect of proper home insulation; if you don’t have a vapor barrier or you have an inadequate vapor barrier between the walls/ceiling and your insulation, moisture can form where the warm air inside the house meets cold air outside the house (yep, you guessed it in your wall and ceiling spaces) – this is a sure way to reduce the efficiency of your insulation
  • what is the ACH of your home?  If you’d like to know, you can hire a professional home energy auditor to actually do a test and help diagnose where you’re losing precious air (using a blower door) or heat (using an infrared camera like the one used to take the picture above)

All of these items are very likely to require additional cost and you’ll probably want a professional involved in order to do it right.

Whatever path you choose, the effort you put into increasing the energy efficiency of your home will pay dividends – first through your own knowledge and peace of mind that you’ve done more than change the lightbulbs.  And once you’ve done a few of the items above, you’ll hopefully see the other type of green savings – that of saving $ on your utility bills.

Tips for selecting heating systems

Tuesday, November 4th, 2008

Winter is now upon us and things are beginning to get colder.  It’s the time of the year when you begin to think of turkey, the holidays, snow and heating systems.  Heating systems?  Yes, if your system is ready for an upgrade, now is the time to get it replaced before the weather gets really cold.

Seth Swetman, Owner, America's Best Heating and AC

Seth Swetman, Owner, America's Best HVAC

There are so many types, that it can be overwhelming to know how to choose the right one for your needs. Recently, we spoke to Seth Swetman, owner of  highly-rated local Seattle area business America’s Best Heating & Air Conditioning about what factors you should consider when looking to put in a heating system this holiday season. Here are the 3 tips he gave us…

  1. Energy Efficiency – The most important thing now is energy efficiency. We are getting a lot of interest in duel fuel heating systems now, which is a gas furnace with a heat pump. This is the most efficient heating system you can buy. The savings compared to just a gas furnace or electric heat is 1,000.00- 1,500.0 a year. People are installing this system then seeing a payback in less than 5 years. That is at today’s costs. The energy costs can go up 5% a year on average. You get the best system and cooling in the summer time. It’s the best of both worlds.  More on home energy efficiency.
  2. Free Money – Most people aren’t aware of the free money available when you upgrade.  Puget Sound Energy is offering a rebate of $350 with purchase of a high efficiency gas furnace and $350 on the installation of a heat pump.  This program is renewed on a year to year basis.  This is a great plus you enjoy saving money every month with your new high efficiency equipment.
  3. Air Quality – We’re seeing a lot of interest in products that improve inside air quality.  Many people are suffering from allergies, pet dander and just plain old dust in their homes.   One of the best products out there is a Honeywell electronic air cleaner which is 99.9% efficient at removing dust and pet dander down to 0.5 microns.  My wife, Laurie, has allergies and has seen a dramatic improvement in her allergy reactions after we installed this system.

I hope this information is helpful to anyone out there looking to put heating in this winter. If you have other tips from your own experience, please leave a comment.
