IS YOUR OUTDOOR UNIT ON FIRE?

IS YOUR OUTDOOR UNIT ON FIRE?

We frequently get panicked calls from customers who report that the outdoor unit of their heat pump system is on fire, with smoke pouring out the top of the unit. Thankfully, this is generally not the case. During the course of normal heat pump operation, frost forms on the ODU’s coil, and this needs to be defrosted to keep the system running efficiently. The unit will go into defrost mode, and in cold weather it causes a large amount of steam to pour out of the top of the unit. The defrost cycle is brief, so if you notice this phenomenon at your home, go out and make sure that you don’t smell actual smoke…the defrost cycle typically lasts 1-7 minutes, and is usually accompanied by a hissing sound. The ODU’s fan will not be spinning during this process. Just a word to the wise! Visit our website for helpful HVAC DIY tips…. www.comfortheatingandac.com

WINDY WEATHER TIP!

This is going to sound super-simple, but it’s effective. For homes with older, leaky windows–draw your curtains during windy weather to keep heat from escaping. The same applies with older doors–simply put a towel at the base of the door to keep the heat where it belongs–inside!

Is Your Gas Furnace Killing You?

Captain AC — Tue, 11 Oct 2011 20:19:13 +0000

OK, the title is a bit dramatic, but unfortunately it’s rather true.

When gas is combusted in your furnace, it passes into a “heat exchanger,” a steel device that heats up, with resultant heat being disbursed through your home via a blower. The heat exhanger is made of steel, and become reusted (due to a leaking evaporator coil or from the natural condensation formed from combusted gas). When the heat exhanger rusts enough, holes form and carbon monoxide is passed into your home through the ductwork.

This is not good!

Yearly checkups of your gas furnace are critical for a number of reasons, and this carbon monoxide issue may be one of the most important reasons to have your system checked yearly.

Make sure to keep carbon monoxide detetcors throughout your home–preferably one that plugs in and has a battery backup. Call your local HVAC company at the first sign of carbon monoxide detection!

Shedding Light on HVAC Solar

SHEDDING LIGHT ON SOLAR

Solar power has been around for a long time, and recent advances in solar technology have started to make it a truly viable option for residential HVAC applications. Lennox is now offering solar systems that will completely power straight AC systems, and up to 66% of a heat pump’s energy (for most Virginia residents). These solar systems will actually send power back to your utility company (during low demand periods), offering you a credit on your utility bills. In addition, there are substantial federal tax credits for solar installs (up to 30% of the cost), and “renewable energy credits” that offer $120 for every 10,000 kw hrs. produced by your system!

Lennox has an excellent website that should answers all your questions about how these systems work, and there is a great calculator that show exactly how much energy you can save with various configurations of panels vs. systems.

Before you delve too far into the wild world of solar, here’s the bottom line—these systems aren’t cheap, and are suited for homeowners that plan on being in their home for more than 10 years. This 10-year mark is a general break-even point for cost vs. savings.

Thermostat Etiquette – Save Money AND Your System!

Thermostat Etiquette – Save Money AND Your System!

Here are a few simple tips in the realm of Thermostat Etiquette:

1) For non-programmable thermostats, try to employ a “set it and forget it” attitude with your thermostat. Between 72 and 74 degrees is optimal for heat pump operation. The less you change the temperature on the thermostat, the less the system has to work to match your request. When you do adjust the temperature, keep changes within an eight degree range (in other words, don’t move a thermostat from 74 to 64, as the unit will run a very long time to get the job done–money out of your pocket and strain on the system).

2) With programmable thermostats, setting a range of temperatures is fine, but keep the range within an eight degree split. Let’s use a thermostat with “Wake, Leave, Return, Sleep” settings as an example. Many of customers use the following settings, which use a six-degree split: Set the thermostat to have the home at 72 degrees when you wake, 78 degrees when you leave, 72 degrees when you return, and 74 degrees while you are sleeping. Most programmable thermostats (such as the Honeywell 8000 or Lennox’s iComfort) have an “intelligent recovery” feature, which allows the system to gradually achieve the various temperature settings. It will typically start working an hour before the desired temperature change time.

3) Keep in mind that one of the summertime functions of a straight AC or heat pump is to remove humidity from your home. Anytime you open a window, humidity can enter the home and send the system into work mode to get rid of it. It’s actually best to keep your home “sealed up” throughout the summer to keep your dehumidification working in an optimal fashion. Conversely, systems installed with a humidifer (highly recommended with any gas furnace) keep moisture in your home during the winter, and the same concept applies (although you are probably less apt to open windows in the dead of winter!)

BUYER BEWARE – HVAC INSTALLATIONS

Captain AC — Fri, 05 Aug 2011 18:20:50 +0000

Here’s the bottom line–your HVAC installation is only as good as your installer.

We’ve been in the HVAC business for over thirty years, which is wonderful for knowing that we will be there for you years down the line, but i unfortunately has ZERO to do with the actual installation of an HVAC system in your home. The experience you need to worry about is that of the installing technician.

Why? You can buy the best, most efficient system out there, and if the installation job is shoddy, that swanky system can easily fail in just a few years. As an example–if any moisture is allowed into your refrigerant lines (which can happen to inexpereienced techs in humid weather), the system will run fine at first. Over the course of a few years that system will eventually fail as the moisture keeps getting pumped through lines that are designed for freon only.

Our advice–not only look for the best deal & system, but look for the best install crews. Not only ask the age of the compnay you’re buying from (which is important), but also find out the experience and credentials of the actual crew that will be installing your system.

What in the world ARE “Capacitors” and “Relays?”

Captain AC — Fri, 01 Jul 2011 19:06:44 +0000

You may have gotten an HVAC service ticket with the diagnosis of a bad “capacitor” or a bad “relay.” They are one of the more common problems that we diagnose and repair.

So what exactly are these things?

A CAPACITOR is an electrical component that stores energy. It gathers and stores power while the unit is in operation, and releases the charge when needed at time at start-up. Capacitors control the start-up of your outdoor unit’s fan and compreesor. If your system is blowing air, but it is unheated or uncooled–this could be indicative of a bad compressor (although other components could be the issue). Capacitors are round or oval cylanders, and will bulge and even burst when they are going bad or are completely blown.

A RELAY is an electrical component that basically acts as an on/off switch. Relays control your indoor unit’s fan. You may have noticed that when your system turns on, the indoor unit’s fan will energize shortly thereafter–that’s your relay at work! Relays cometimes get stuck, causing your unit to either run continuously (if stuck in the ON position), or not at all (if stuck in the OFF position). A blown relay will not allow the system to run at all.

The Most Important HVAC Tip EVER – Save Money, Change Monthly!

Captain AC — Thu, 12 May 2011 18:55:58 +0000

What’s the tee-total most important thing you can do to maintain your HVAC system? Change your filters monthly! It’s simple, it’s cheap, and it’s critical.

I am still amazed at the deleterious effects of a dirty filter…yet I have a hard time remembering to do it in my home…a monthly note on my calendar has helped.

A dirty filter equals a system that can’t breathe, struggling to get the air it needs to function. As the system struggles more and more, strain is placed on…everything…within the system.

But wait, it gets worse–once a filter gets dirty enough, the particulate matter it is designed to catch starts passing through to your evaporator coil (which is the heart of your indoor uniit). Dirt in this coil is bad…very bad. Cleaning an evaporator coil isn’t cheap, and there’s always the possibility that too much damage has occurred and it has to be replaced completely. I’ve actually seen filters that got so clogged that they folded in on themselves and got sucked right to the coil. Not good….

You don’t need to purchase the fancy jobbies that tout baking soda or allergen fighters (these additives can actually reduce the effectiveness of the filtration)–just basic poly filters will do. With monthly changes it’s all you need.

Filter changes–it’s simple, it;s cheap, and it’s critical–same money, change monthly! Visit us at www.comfortheatingandac.com for more DIY tips!

PETS – GREAT FOR THE HOME, BAD FOR HVAC!

Captain AC — Fri, 08 Apr 2011 16:25:58 +0000

Pets – Great for the home, bad for HVAC!

For many people, pets make our homes complete. Unconditional love and tons of fun, but unfortunately they can also kill HVAC systems. With some simple preventative maintenance, these pet-related issues can easliy be circumvented. Some basic points to ponder:

1) Outdoor Units and Urine: Dogs seem magnetized to outdoor units, finding them second-only to fire hydrants as fantatsic spots to mark their territory. Unfortunately, pet urine on an outdoor unit’s coil isn’t good. It corrodes away the delicate fins that are critical to the system’s function. Solution – keep your outdoor unit protected with some kind of barrier (at least a foot away from the unit itself to allow it to breathe). Latticework is a great solution for this, as it’s decorative and protective at the same time. While we specify pet urine here as being problematic, it should probably be noted the human urine is just as bad…while we hope this isn’t an issue in your neighborhood, it’s something to keep in mind! HA!

2) Outdoor Units and Pet Hair: Your outdoor unit is constantly sucking in air, and unfortunately pet hair also gets sucked up to the outdoor unit’s coil. We’ve gone on some service calls where the outdoor unit resembles more of a big box o’ fur rather than an HVAC system. The more hair that collects on the unit, the more the system struggles to get the air it needs to function. Just like with a dirty filter in your home, this struggle to breathe will eventually culminate in failure of parts, even the entire system as a whole. Solution: Again, put up that latticework to help curtail the fur flow. Also–LIGHLTY rinse your outdoor unit with water, keeping in mind that there are electrical components “close to the surface” that can be damaged if you douse the unit with a torrent of water. As an alternative, you can gently pick tufts of hair off the coil, being careful not to bend the unit’s delicate fins.

That’s about all it takes to pet-proof your HVAC system! Simple solutions to solve what can become complex problems!
