Dry Winter Air

Wednesday, October 5th, 2011

Do you get dry itchy skin in the cold Louisville winter? Are you concerned about your wood floors and furniture being too dry? We can help with a whole house humidifier.

Whole house humidifiers are mounted on your furnace duct system and controlled automatically by a humidistat in conjunction with your thermostat.  Three primary types of humidifiers are steam, fan powered and bypass. The steam humidifier uses significantly less water than the other two. It also works well with all types of heating systems.

In addition to making the air moist, it will also make the ‘cooler’ air more comfortable. This allows you to keep the thermostat a couple degrees lower for the same comfort level. In turn, you save on your heating bill.

Honeywell TruSTEAM humidifiers are the preferred choice of Certified Comfort. We’ve installed them in our own homes as well as customers’ homes. Call 244-HEAT today to schedule an appointment to see which humidifier is right for you.

My Review of the Transit Connect

Sunday, August 21st, 2011

I wrote this article for The Smart Van, but decided to place it here, too. Love this new ride…

The Smart Van crew asked me to review the Transit Connect (TC) in late June. However, I hadn’t even put 1000 miles on it and wanted to have some more saddle time before submitting a review. Well, it’s been a busy summer and I’ve been driving the TC for two months now. I absolutely love the TC. I certainly wish I could have purchased this van two years ago. Why all the love? I’ll get there in a bit.

First some background about my company setup. We are a three-man company servicing the metro Louisville, KY, area. I am the owner and service technician. We also have an installation technician and a salesman, who doubles as an installation helper.  From time to time, I assist on installations when service calls are slow.  So, most of my time is spent moving from site to site.

On to the review…

Big plus is the fuel economy of 20-22 MPG. I was in a Silverado 2500 with ABC Service Body and was getting 10-13 MPG. I’ve thoroughly enjoyed the 80%+ savings in fuel over the summer.  The decrease in engine size from eight to four cylinders took a little adjusting. I learned that the gas pedal does go all the way to the floor for a reason. I really have no problem getting into traffic. I have a harder time jumping into my personal driver. Nearly broke my neck when I jumped on the throttle after driving the TC for a month straight.

All my service items are quickly accessed without entering the van. My tool bag and gages are kept on the driver side cargo area next to my refrigerant jug rack. Refrigerant manifold hangs on divider screen. Behind my bag and attached to the divider, I’ve mounted my oxy/acetylene setup as well as three tank holders – oxygen, nitrogen, and acetylene. The passenger side of the cargo area is plenty for an evaporator coil, heat exchanger or compressor.

They key to managing the TC is the shelf package and bin system. If you are trying to use old school side wall mount racks, you will never put enough apples in the apple cart. If this is a dedicated service vehicle (read — no equipment hauling), then you must purchase the Katerack Four Shelf system. Each shelf can hold 300#. http://www.dejana.com/tc/vanupfits/vanSpecialtyPackage4.html

Katerack Shelf Package

The picture from the OEM is overloaded with tools but you get the idea of the shelves. I’ve yet to add bins to organize my PVC and copper. They’re sitting in a couple of milk crates. A friend of mine runs a fleet of these vehicles. They put more inventory on the TC than they can the E350! Plus, everything is right there on the shelf. Inventory loss is VERY low for him. Without organization, I already have more service stock on the TC than my Silverado. Plus cargo and stock areas are extremely accessible. I sure don’t miss climbing in the bed of my truck to get refrigerant, nitrogen, etc. from my Jobox.

Inventory counting is extremely easy with the shelf package. Everything is right in front of you. I can count my inventory in less than ten minutes. Certainly makes supply house stops more productive.

You’ll want to upgrade to the 255° doors. They have stops at 90° to keep them from flying open. However, a simply button push lets the door swing to the side of the van and lock to magnets. Then, you can access the back of your shelves

My ladder racks include a curbside lowering type. No climbing on the van to remove the 22′ ladder. Driver side short ladder requires me to stand on the back but that’s my own doing because I carry a 13′ Gorilla ladder.

A neat feature of the TC is the overhead storage area in the passenger area. I keep service contracts, brochures, equipment stickers and invoices there. Certainly keeps them in good shape. Plus, I don’t have to hang a folder from the divider.

Pricing is fairly the same around here. You can be out the door with the full upfit package (fancy ladder rack, tank holders, cage/divider, and shelves) on an XLT for around $25K. I went with XLT for the keyless entry, power windows and CD player. If I’m spending half my life in a van, I want to enjoy it.

If there’s a downside, it’s the inability to pull a trailer. There are times that we are so busy that I’d like to haul some equipment to the job but can’t do it. However, my equipment distributor makes job deliveries with a day’s notice. So, we’re covered if we need it.

Overall, I am thoroughly impressed with the Transit Connect. The first service technician I hire will go immediately into a TC.

Should you turn the HVAC system OFF when gone?

Wednesday, July 6th, 2011

I was recently asked on a Google+ discussion if you should turn your air conditioner OFF when gone. Plenty of room for disagreement even among the professionals. When taking a purely energy conservation viewpoint, you’ll definitely save when using setback periods. However, we buy these HVAC systems for comfort. How comfortable is an 80*F home after climbing from your 65*F car and the 50*F vents blowing on you during your commute? Not really comfortable.

Programmable Thermostat

There’s a simple solution to help – a programmable thermostat with dehumidification capabilities. Research shows use that humans are most comfortable when the humidity is 40-60% and the indoor temperature is 68-78*F. A home at 78*F and 50% humidity has the same comfort feel to most people as a home at 70*F and 60% humidity.

What about dehumidification? Let’s consider the function of an HVAC system in cooling mode. It’s purpose is to cool and remove moisture. If you’re in a deep setup, then the AC won’t be running. If it’s not running, then it’s not removing moisture. So, I prefer the programmable thermostats that can also dehumidify. They do this by cycling the system for 10 minute periods when there is no active call for cooling.

With that, I recommend a setback similar to the EPA (Energy Star):http://www.energystar.gov/index.cfm?fuseaction=find_a_product.showProductGroup&pgw_code=TH and http://www.energystar.gov/index.cfm?c=thermostats.pr_thermostats_guidelines.

Keys to the savings: setback period should be at least ten hours and 7*F (heating) and 4*F (cooling). Read the footnote on the second link.

What about my own home? Cooling 78*F. Heating 68*F. Set to dehumidify to 50%. Today it’s 78*F in the home with a humidity of 44%. Very comfortable. Actually a bit of a chill as I entered from work. Set it and forget it because we are gone less than ten hours at a time.

Why Air Flow is Critical to HVAC Life

Sunday, July 3rd, 2011

One of the many things we check on our service calls is system air flow. Air flow is critical to a long lasting air conditioner and furnace. Why? Let me explain.

I’ll first cover the heating side, your gas furnace. Inside your furnace is a heat exchanger. The flame shoots inside the heat exchanger and the fan blows air across the outside. If the air flow is insufficient, the heat exchanger becomes too hot. This excess heat stresses the metal. Over time, this stress leads to cracks in the heat exchanger. That is a fire and carbon monoxide hazard. By law, we are required to disable and tag a furnace with a cracked heat exchanger until the furnace is repaired or replaced.

What about the cooling side? Above your furnace is an air conditioning coil. Refrigerant (you may call it freon) flows inside the coil. The furnace fan blows air across the coil to cool the air and your home. When the air is cooled, heat is being transferred to the refrigerant. We need enough heat added to the refrigerant to boil all of it because the compressor in the air conditioner is designed to only pump gas (completely boiled refrigerant). If there is any liquid, compressor damage will occur.

In summary, proper air flow is important to both the heating and cooling sides of your HVAC system. There’s nothing more important during the design and installation of your system. Proper air flow ensures a long lasting system.

Waiting To Replace Your HVAC System

Tuesday, June 14th, 2011

So, you are considering selling your Louisville home but your air conditioner is not working well. Do you live with it thinking you won’t be in the home in a couple of years or replace it with an energy efficient air conditioner and furnace?

Three reasons to replace that dinosaur system now.

1 – If it’s more than ten years old, it’s up to 30% less efficient than today’s minimum efficiencies. You’ll save on energy consumption with a new system.

2 – Utility rates increase every year. No matter how much we dislike it, LG&E gets their rated increase approved annually whether it’s electric or natural gas rates. Back to point number one, you’ll save money with a new system.

3 – Let’s say you you do put your house on the market. The buyers will use the age and condition of your heating and cooling system as a negotiating point. A new HVAC system eliminates that point. Plus a stack of lower utility bills is on your side of the negotiating table.

If you can afford to do it, purchasing that new system makes sense.

Rob’s Crockpot Pulled Pork

Saturday, June 4th, 2011

A friend of mine asked for my pulled pork recipe on Twitter. Since there aren’t enough characters to share a recipe there, I’ll share it here. We are a family on the go and are always looking for easy meals. This is one of my favorites.

Ingredients:

  • Pork loin
  • Onion
  • Desired spices

Start with a pork loin that’s big enough for your family. I like to cook 1/3 pound per serving. Nice to cook a little extra for a couple of lunches.

Place your pork loin in the crock pot. Cover 2/3 with water.

Thinly slice your favorite onion and place on the pork loin. I use just enough to cover the top of the loin.

Add any additional spices that you’d like to the water.

Cook on high for 4 hours or low for 6-8 hours. I usually start the crock on low as we’re leaving in the morning, and the meat is tender by arrival from work.

Remove the loin from the crock and carefully place on serving platter as it’s hot and tender. I like to use two forks like a big cob of corn. Then, use the forks to pull and separate the loin.

You can leave it plain at this point if the kids don’t like barbecue sauce. When we have a family gathering, we place the pulled pork back in the crock (after draining water) and mix with barbecue sauce. You can serve right from the crock and keep it warm in the crock. We leave it plain when it’s just the four of us as the kids prefer ketchup. Ya, they’re kind of weird like that.

Anyhow, there you have it. That’s our super simple pulled pork recipe.

Repair or Replace

Monday, May 30th, 2011

When our Louisville clients have a major ac repair, we are often asked if they should replace the HVAC system or simply repair the air conditioner.

Two factors influence the decision the most: age of your HVAC system and cost of the repair.

If it’s great than ten years old and you have a major repair (compressor, condenser fan motor, evaporator coil), you should seriously consider a new heating and cooling system. An HVAC system of that age is not nearly as efficient as today’s system. Plus, a new air conditioning system has a 10-year parts warranty standard with 10-year labor warranties available.

If you’re on the fence regarding a new system, here are some things to consider. First, your old system is considerably less efficient than a new system. So, your energy consumption is higher the longer you wait. Second, air conditioners and furnaces increase in price roughly 3% each year. You’ll pay more for that new system the longer that you wait. Combine those two, and you can see why waiting to purchase a new HVAC system may not be the best choice.

If your HVAC system is under 10 years, then repairing it may be your better choice. We offer a two-year guarantee on all of our repairs. Plus, we can show you ways to save money on future repairs through our service agreement program.

Give us a call today at 244-4328 or send us an email via our contact us page.

Continuous Fan or Auto Fan

Thursday, March 3rd, 2011

Louisville HVAC clients often ask how they should operate their furnace fan – auto or continuous? So, what should you do? Well, it depends…

If you have a high efficiency filtration system and a variable speed ECM blower, you will want your fan running continuously to circulate the air at a low velocity. The lower speed of continuous fan allows for better filtration. The continuous fan will provide more air exchanges each day. Thus providing cleaner air to the home.

What about the rest of us with standard filters and blower motors? If you live in a humid area where the air conditioning system must remove a lot of moisture, you’re better to leave the fan in Auto. You can see as much as a 10% reduction in indoor humidity during the summer. Continuous fan will evaporate the water from the coil that the air conditioner just removed. So, there’s a trade off between circulating the air and humidity control.

Another consideration is register location. If they are placed low on the wall, then the air likely blows on you. You wouldn’t want room temperature air blowing on your skin during the winter. Probably wouldn’t feel to bad in the summer. So, maybe you’d be better only running continuous fan in the summer.

So many things to consider. I suggest running the fan in the mode that makes your home the most comfortable. If you just can’t get comfortable, then gives a call (244-HEAT), we’ll be more than happy to provide a system evaluation.

Hybrid Heat

Tuesday, March 1st, 2011

Louisville utility rates are on the rise. Conventional gas furnace and air conditioning systems can be a burden on the budget. Have you considered a hybrid heat system?

Hybrid heat systems consist of a heat pump and gas furnace. Most homes in Louisville utilize an air conditioner and gas furnace. Most older furnaces are 68 to 80% efficient.  All York condensing furnaces are at least 95% efficient. However a heat pump is 200-300% efficient! You can utilize the heat pump in weather over 30F to provide super efficient heating.

Our most popular hybrid heat system consists of a two-stage gas furnace with variable speed motor and a 15 SEER heat pump. This system offers the savings benefit of the hybrid system and the comfort of two-stage gas heat. Our most recent installation utilized a two-stage heat pump, too. Our client has four stages of heat! Talk about comfort!

If you’d like to know more about a hybrid heat system, send us an email or call us today!

HVAC Tax Credits Revisited

Saturday, December 18th, 2010

The Bush era tax cuts have been extended along with several tax credits.  Among those extended are the 25C tax credits for HVAC upgrades. In 2010, qualifying heat pump and furnaces were  eligible for a 30%  credit for the first $5000 in upgrades ($1500 maximum). What qualifies? See this link. (Energy Star site.)

In 2011, this credit rolls back to the 2008 levels. Here’s a summary (hat tip to ACCA Insider):

For 2011, eligible taxpayers would be able to claim up to $500 in tax credits for installing energy efficient equipment, but the most a taxpayer could claim for a qualifying central air conditioner or heat pump would be $300, $150 for a qualifying furnace, and $50 for a qualifying advanced main circulating fan.

The tax extender package reinstates the lifetime credit caps, which disqualify any homeowner who has claimed more than $500 in 25c tax credits since January 1, 2005, from any further credits.

The tax extender package also modifies some of the minimum standards to qualify for the tax credit. The qualifying guidelines for natural gas and propane hot water boilers, and oil furnaces and hot water boilers are increased to 95% AFUE. Changes to the qualifying standards for central air conditioners, and heat pumps in effect in 2009 and 2010 remain the same for 2011.

The short version: If you waited until 2011, you may still be eligible for $500 in credits if you haven’t claimed the credit since 2005.
