Montgomery Village HVAC Guide: How to Install a Programmable Thermostat

Wednesday, February 29th, 2012

Programmable thermostats are one of the best ways to save on heating costs, especially if you have a hard time remembering to turn down the heat in your Montgomery Village home. Installing a programmable thermostat will allow you to set the times you want the heat turned up or down. Not only will this make heating your home more consistent and save energy, but it will also allow you to tailor your heating needs to your schedule.

For instance, you can set the thermostat to turn on before you get up in the morning so that the house is already warm when you get out of bed, and conversely, set it to turn down after you go to bed or leave the house for work. Depending on the brand and setting options, programmable thermostats are relatively inexpensive and easy to install.

Although all styles are slightly different, here are some basic instructions that show you how easy it is to install a programmable thermostat.  Remember, this is only a general guide; always check the instructions inside the packaging of your new thermostat before you install it, or check with an electrician. Remember that Tuckers Air Conditioning & Heating has highly trained professional technicians that can help you install a new thermostat for your heating and air conditioning system.

1. Remove the Old Thermostat

Before you remove the old thermostat, check to see where it’s mounted. If it’s mounted to an electrical box, the voltage used to power the old thermostat may not be compatible with the new one. Ask a certified electrician or heating technician if you aren’t sure.

CUT THE POWER TO THE HEATING SYSTEM TO AVOID ELECTRIC SHOCK. You should always turn off the main power supply to your heating system before installing any new thermostat. If you aren’t sure how to do this, ask your Montgomery Village HVAC contractor. Once you unscrew the mounting plate for the old thermostat, just unhook the wires. Don’t throw an old mercury controlled thermostat. You should ask your local waste management facility how to properly dispose of mercury products.

2. Locate all Wires

Wrap the loose wires around a pencil to keep the wires from falling back into the wall. Identify and label each corresponding wire with a letter (do not use color coding since this is not always accurate). Strip the plastic off the ends of the wires about ¼ inch if you need to.

3. Install and Insulate Wallplate

If the area around the new wallplate is larger than the plate, insulate the hole with non-flammable insulation. Take the wallplate off the programmable thermostat and hold it against the wall to mark the screw holes with a pencil. Pull the wires through the large opening at the bottom and screw the plate to the wall.

4. Wiring

Make sure you are comfortable with wiring before you attempt to do any electrical installations. Check the manual for your programmable thermostat for instructions on wiring that specific model. In general, you’ll want to make sure you match the wire labels with the corresponding terminals on the thermostat. Sometimes there will be extra wires that aren’t needed. Always test it before completing the installation. Don’t forget the battery!

5. Install the Faceplate

Once you have it wired correctly, all you need to do is align the brackets on the faceplate with the corresponding slots on the wallplate and fasten the faceplate to the rest of the mounting. Lastly, tighten the screw at the bottom of the thermostat to hold it in place.

If you have any questions regarding programmable thermostats or this seems much too complicated for you to do on your own, give Tuckers Air Conditioning & Heating a call.

Kensington Heat Pump Tips: What Happens When You Neglect Maintenance

Monday, February 27th, 2012

Just like any HVAC system, the heat pump in your Kensington home needs routine maintenance and yearly check-ups to operate as efficiently and safely as possible. You also don’t want your heat pump to wear down to the point of a major malfunction or breakdown, which can be costly to repair or may require a complete system replacement.

Here are some things that could go wrong and cost you a lot more in the end if you don’t keep up with the regular maintenance of your heat pump.

Damage to the Compressor

The compressor in a split-system heat pump works whether you are heating or cooling your home. In the winter, the compressor reverses the flow of the refrigerant to defrost the outdoor coils, and in the summer it supplies the refrigerant to cool the home, as well as cooling the outdoor coils. Proper airflow is vital to keeping the compressor running smoothly. Filters that are not changed regularly, dirty coils, and dirty fans can all restrict airflow, which will damage the compressor. Debris around the outside components should also be cleared to allow proper airflow.

Decreased Efficiency

When dirty or broken components restrict the airflow, this damages the compressor and decreases the heat pump’s efficiency levels.  Not only is it important to clean your heat pump regularly, but you should also have it checked by a certified heating technician once a year. This will also prevent safety hazards and other hidden issues with the heat pump.

Improper Refrigerant Levels

Most heat pumps are charged with refrigerant at the factory; however, if models that are charged when they are installed are not given the right amount of refrigerant this can also affect performance levels. Refrigerant leaks and other common problems can be prevented by scheduling an annual maintenance visit with one of our qualified Kensington technicians.

Don’t wait until the heat pump in your home stops working, call Tuckers Air Conditioning & Heating to schedule your yearly check-up.

Silver Spring Heating Advice: Simple Steps to Prevent Heat Loss

Friday, February 24th, 2012

There are two fundamental ways to make your Silver Spring house warmer. One is to generate heat, which is the job of your furnace or boiler. The second is to keep the warm air in — and thereby keep cold air out — which is the job of your system of insulation.

The idea that the physical structure of a home can be a component of the HVAC system is one that is often overlooked, but when you think about it, it makes sense. The insulation, windows, doors and building materials that comprise your home are designed to keep the place warm against the cold and vice versa.

So, when bolstering your HVAC system to promote efficient heating, it is important to also consider heat loss and how to prevent it. This is a process that can get out of hand if you go overboard, so it is important to prioritize. Let’s look at the top 3 places to start when trying to prevent heat loss.

  1. Doors and Windows:  If you have older doors and windows, they could be a source of heat loss in your house, even if they are always closed. Replacing your windows and door with Energy Star rated ones will make sure that you are not losing heat to the outside AND still getting all the heat energy from the sun. Installing storm windows or putting up heavy curtains in winter can also help cut down on your heat loss.
  1. Seal off drafts. If any opening to your house, such as windows and doors, is improperly sealed, improperly installed or if the surrounding construction is deteriorating, you can lose a lot of heat. Check any drafts that you notice that might indicate a problem, and also if your vents and air ducts are leaky.
  1. Start at the top. If you want to go farther in sealing your house up against the cold, it is time to work on the insulation. When installing new insulation, remember that heat rises, so you get the most bang for your buck by starting at the top. If you only have the budget or time to insulate one space, make it the attic. You can work down from there.

These areas should be your top three priorities on your mission to prevent heat loss in your Silver Spring home. If you start here, you will get the best gains with the least effort. For more information on how to reduce you heat loss, give Tuckers Air Conditioning & Heating a call!

Germantown HVAC Tip: Benefits of Getting a Home Energy Audit

Wednesday, February 22nd, 2012

You may have heard of home energy audits, in which you inspect your Germantown home to find ways to improve its energy efficiency. What you might not know is all the ways an audit can help you save energy and be more environmentally friendly. Here are the four main benefits of getting a home energy audit:

Learn About Loss

The main idea behind getting a home energy audit is to figure out the heat loss (or gain) of your home. That is, how much heat are you losing to the outside world? Heat that doesn’t stay in your home obviously does little to benefit you in terms of keeping your house warm, and can be costly in terms of increased utility bills and repair costs over time.

 Identify Weak Spots

Aside from determining how much heat your home is losing, a home audit can also point you in the direction of weak or thin spots in your home’s insulation. By identifying areas that are letting out the most heat, you can prioritize your strategy to prevent heat loss. Most often, this starts with doors and windows.

 Opportunity to Upgrade

A good home energy auditor will present you with solutions for your heat loss problems, creating an opportunity for you to upgrade the equipment or materials in your home. This can solve your heat loss problems in one fell swoop. Such solutions include energy efficient glass, new sealant around doors and windows or upgraded insulation, especially in upper floors.

 Save Money

Preventing heat loss increases the efficiency of your heating system, which saves you money. Your heating bills are reduced, and your furnace has to run less, which means fewer repairs and a longer life for an expensive piece of equipment. In short, spending money on a home energy audit and heat loss solutions are sound investments.

The benefits of a home energy audit are numerous, which is all the more reason to take advantage of having one done in your Germantown home. It is also a good thing to do for the environment! For more information about home energy audits, give Tuckers Air Conditioning & Heating a call!

Bethesda HVAC Advice: Seasonal Air Quality Control

Monday, February 13th, 2012

For people who suffer from seasonal allergies in Bethesda, air quality is a key concern. Allergens in the air cause brutal bouts of sneezing, runny nose, itchy eyes and even sinus headaches. Even taking refuge indoors will often not assuage these symptoms, as indoor air is often comparable to outdoor air in terms of allergens and overall quality.

That is, unless you take care to control the seasonal air quality in your home, which can not only help ease the suffering of allergies, but also soothe asthmatics, keep out pollutants and generally promote better overall health.

How do you go about controlling the air quality in your home? To start, try these simple tips:

  1. Vacuum carpets regularly. Use a vacuum with a HEPA filter and invest in some allergen suppressing bags.
  2. Keep your vents clean. This is also a good maintenance practice to lengthen the life of your ventilation equipment.
  3. Dust hard surfaces and wash bed linens weekly.
  4. Install HEPA filters in your ventilation system, such as in air conditioners or other air handler units. Use a higher rated filter to keep out more allergens and pollutants.
  5. Invest in and use an air purifier. Again, make sure to get one with a HEPA filter.
  6. Have your home tested for radon and carbon monoxide. Have smoke, carbon monoxide and radon detectors working properly at all times.
  7. Use a humidifier to keep overly dry air from irritating sinus passages.
  8. Keep doors and windows closed tight, especially during allergy season(s).

By taking charge of the air quality in your Bethesda home, you also take control of a measure of your family’s health. Some of these measures require at least a bit of an investment – for example, higher rated HEPA air filters are often more expensive and need to be changed more frequently – but the benefits to your well being and that of your family are clearly well worth it. If you have any question about what type of indoor air quality system will work in your home, give Tuckers Air Conditioning & Heating a call today!

Chevy Chase Indoor Air Quality FAQ: Things Your Air Filter Can’t Filter

Friday, February 10th, 2012

Air filters are great to have in your Chevy Chase home. Many people who own air filters, especially those who suffer from allergies or asthma, swear by them as being very beneficial to their health and general well-being. They help you feel comfortable knowing that your air is clean and fresh.

But how confident should you be in your air filter? Is there anything your air filter is missing? Can you be sure that your air is as clean as can be?

Well, all air filters have limitations, and many do particularly well at trapping and removing certain types of air pollutants, but at the expense of letting others pass. What your air filter can and cannot do depends on what kind of equipment you have.

A conventional air filter, like the pleated kind you may have in your air conditioner, is designed to trap particles in the air. Pollen, dust, dander and other small but solid pollutants and irritants get trapped in their close-knit fibers. The thing to pay attention here is the filter’s HEPA rating—the higher it is, the smaller the particles it can trap. So, if you are using a lower rated filter, you may be trapping pollen but still breathing in smoke particles. Also, sometimes large, heavy particles settle before reaching the filter and can’t be trapped.

A less common option is the gas-phase air filter. As you may guess from the name, these filters are meant to filter out harmful gases in the air. They do not trap particles and usually have a short life, so they need to be replaced frequently.

In addition to filters, there are other air cleaning options like ultraviolet germicidal (UVG) lights and photocatalytic oxidation (PCO) cleaners. PCOs are meant to filter out harmful gases, but have limited use in homes. UVG lights use radiation that is harmless to people but deadly to microorganisms to pure air of bacteria and other pathogens.

In sum, if you are concerned about the quality of the air in your home, the best strategy is probably to use multiple solutions, such as a combination of an air filter and UVG lights, in order to get rid of as many pollutants as possible. Keep in mind, though, that no system is perfect in keeping everything out of your air. If you need help choosing the right system for your Chevy Chase home, call Tuckers Air Conditioning & Heating today!

Olney Heating Installation Question: What Is a Load Calculation and Why Is It Important?

Wednesday, February 8th, 2012

An integral part of designing and installing a heating, ventilation and cooling system in our Olney home is the load calculation. Calculating the load of a room, home, or building essentially consists of determining how much heat is lost and gained within that area. A proper load calculation is critical to installing an appropriate HVAC system, as well as ensuring maximum efficiency or diagnosing problem areas of an existing system.

The Load Calculation Process

When conducting a load calculation for your home or office, a professional will consider several factors that can affect heat loss and gain. First among these is the construction of the building. This includes not only cubic footage, but also the type of material making up the walls, ceiling and floor, as well as any duct work. A professional performing a load calculation will examine the entire building envelope, including whether the walls are wood or masonry, if there are cathedral ceilings, what type of insulation is installed, and so on.

Secondly, load calculation takes into account doors and windows, as these can affect heat gain and loss. The number of doors and windows, as well as the size, shape and material of each one is included in the load calculation. This includes skylights and sliding glass doors, as well as the type of material shading any windows. A professional will look at pane thickness, number of panes in each window, if there are storm windows installed, any drafts in door installations, and even what kind of drapes are on the windows in order to accurately calculate load.

Additional Factors

There are other factors an Olney professional must take into account, including appliances and occupants. Heavy appliances tend to give off heat, as does having a lot of people in a space, so these must be considered in order for an HVAC system to properly regulate temperature and airflow. Last but not least, of course, is the matter of desired temperature change. By how much do you want to raise and lower the temperature of your home or office?

Calculating load prior to installing a new HVAC system is a vital part of the process. It is also a good idea to perform a calculation with current systems, as it may reveal already existing inefficiencies or deficiencies. An inefficient HVAC system not only results in unsatisfactory heating and cooling, but also unnecessary cost due to wasted energy. As you can see load calculation is an elaborate and complex process, but it is necessary for a properly functioning HVAC system.
