Furnace Repair FAQ: Why Doesn’t My Home Get Enough Heat?

Monday, September 29th, 2014

If your home seems uncomfortably cold no matter how high you set the thermostat, chances are something isn’t right with your heating system. There are a number of possible causes for heat loss in your home, but the most common is the furnace. Read on for a breakdown of possible problems with your furnace, and what to do about them.

Power/Ignition Issues

If no heat seems to be coming through the vents, your furnace may be having trouble igniting. The first thing to check is the pilot light. If the pilot light is lit, the problem is elsewhere. If the pilot light is out, it is recommended that you call a professional to re-light it for you. If the pilot light is on, but your furnace is not igniting, the gas valve may be closed. It is also possible that not enough gas is getting through the gas line and into the furnace. Due to the exact nature of determining the right amount of gas to flow into the furnace, it is best to call a professional to diagnose and fix the problem for you.

Delivery Issues

If your furnace is on but not delivering enough heat, the problem may be in the ducts. Check to make sure that heat is coming out of all the vents evenly across rooms. If one room is much colder or does not have heat coming out of it, it is very likely that you have a break in your ducts. Check your air filter as well, which should be located where the return air duct meets the furnace. The furnace repair may be as simple as cleaning or replacing your filter.

If you have checked all of these factors and your home still isn’t getting enough heat, it is time to call a professional.

Why Schedule Annual Maintenance for Your Heating System?

Monday, September 15th, 2014

We are in the last stretch before the cold weather arrives – is your heating system ready to go? One of the best ways to get your heating system in shape for the cold weather and get ahead of any potential problems is by scheduling a fall maintenance appointment for your heating system in Washington, DC. Maintenance offers several benefits that we’ll outline below, and as with any air conditioning services, it’s important to always hire trained professionals. Polar Bear Air Conditioning & Heating, Inc., has been helping customers in the Washington, DC area with their cooling and heating equipment for over 15 years, and we can help you get ready for this winter.

What Happens During a Maintenance Appointment?

Your Polar Bear Air Conditioning & Heating, Inc., technician will conduct the following during a routine maintenance appointment:

  • Full inspection of equipment, including heat exchangers and burn assemblies.
  • Check electrical components, including wiring and terminals.
  • Lubricate all moving parts.
  • Check refrigerant levels (for heat pumps).
  • Check fan belts and adjust belt tension on covered equipment.
  • Provide written recommendations for corrective actions, if any.

Benefits of Annual Fall Maintenance

There are several important benefits to scheduling annual fall maintenance for your heating system:

  • Prevent repairs – no one wants to find out their heat isn’t working on a cold winter day. Scheduling annual maintenance helps you get ahead of possible repairs by spotting them early with the thorough inspection that occurs during a regular maintenance visit.
  • Increase energy efficiency – a tuned-up heater runs better than one that is dirty and suffering from normal wear-and-tear. When your AC runs optimally, it uses less energy.
  • Extend life of equipment – the average lifespan of a furnace is about 15 years. Keeping your heater in good working order can extend this lifespan.

One of the best ways to prepare your home for winter is by scheduling heating maintenance in Washington, DC.

Fall offers a great window of opportunity to schedule maintenance, so contact Polar Bear Air Conditioning & Heating, Inc., and make an appointment with one of our experts today.

The Best Time to Schedule Heating Maintenance in Arlington

Monday, August 25th, 2014

Winter is still a few months away, but the change from summer to fall will start you thinking about how to heat your home for the coming cold weather. It’s likely that the furnace or boiler in your home hasn’t come on for a few months, and during that time it may have developed dirt, dust, damage, or mechanical troubles. When you first turn the heater on to deal with the arrival of cold weather in the late fall, you don’t want to discover an unpleasant surprise when the system either works poorly—or doesn’t work at all!

To prepare your home’s heater, and yourself, for the approaching colder weather, you need to schedule heating maintenance in Arlington, VA from a professional HVAC company. When you call Polar Bear Air Conditioning & Heating Inc. to arrange for regular maintenance, you’ll receive top-quality work from the most skilled technicians around… because those are the only kind of technicians we hire.

When is the best time for heating maintenance?

Right now.

There isn’t a simpler, or better, answer than that. In general, its never too late to schedule heating maintenance—you can’t afford to skip a year—but the ideal period to have the tune-up and inspection work done is during the start of fall.

One of the reasons that this is the best time to arrange for heating maintenance is that the work calendars for HVAC companies are more open during this time of year. Between the air conditioning emergencies and installations of summer, and the many winter repair calls, the fall is a period when technicians have an easier time scheduling work when it’s convenient for customers. Don’t wait until the top maintenance companies are literally snowed-under with emergency heating calls: take advantage of the slower season.

Scheduling maintenance in early fall gives you a good buffer before the cold weather to arrange for any repairs the heater needs to have done. You can probably deal with having the heat shut off in your home for short periods of time if it’s necessary for the repair work. If you should need new heating installation, you definitely want to have some extra time to schedule the work while the weather is still warm.

Polar Bear Air Conditioning & Heating Inc. offers a Preventive Maintenance Program that will take care of both your heating and cooling systems during the year. Our technicians will do a thorough inspection of your heater in the fall to find any potential malfunctions, and then tune-up, clean, and adjust the system so it will perform at high efficiency throughout the winter.

This fall, trust to our more than a decade of experience with heating maintenance in Arlington, VA. Call Polar Bear Air Conditioning & Heating, Inc. today.

What Qualifies a Boiler for the ENERGY STAR Label?

Wednesday, March 12th, 2014

When shopping for a heating system for your home, one of the main criteria you should use to help you select a unit is efficiency. The more efficient a furnace or boiler, the more you can expect to save on your energy bills. You will also help with energy conservation and protecting the environment.

One of the easiest ways to tell that a heater is energy-efficient is to look for the ENERGY STAR label. (And yes, it is trademarked in ALL CAPS; we’re not yelling at you.) In this post we’ll explain what the ENERGY STAR label means and how a boiler in Washington, DC can qualify for one.

To find great installation on an efficient ENERGY STAR boiler, contact Polar Bear Air Conditioning & Heating Inc. We’ve kept the nation’s capital warm since 2001.

The ENERGY STAR label and boilers

In 1992, the Environmental Protection Agency and the U.S. Department of Energy instituted the ENERGY STAR standard for products created in the U.S.A. Appliances, ranging from HVAC systems to computer peripherals, that use on average 20–30% less energy than the federal requirement earn the ENERGY STAR label to show they go beyond the minimum in an effort to conserve energy and save consumer dollars.

According to the ENERGY STAR website, for a boiler to qualify for the label it must have an AFUE rating of 85% or greater. This means that the boiler burns at least 85% of the fuel available to it and converts it into heat. So for every 100 units of fuel, the boiler must generate 85 BTUs of heating, wasting only 15% of its fuel. Features of ENERGY STAR boilers that help them reach this level include: electronic ignition, which means no standing pilot light drains extra power; advanced combustion technology that draws more energy from the fuel supply; and sealed combustion that reduces drafts.

Some boilers are even more efficient

Keep in mind that 85% is the minimum to receive the ENERGY STAR labels. There are models with even greater efficiency. When you are searching for a boiler in Washington, D.C. to keep you warm through the winters and other cold days of the year, look first for the ENERGY STAR label, but also check on the AFUE rating and consult with an installation professional to make sure you are getting the right boiler for your needs.

Trust to Polar Bear Air Conditioning & Heating Inc. when it comes to putting a new boiler in your home. We offer a wide range of services for boilers and other heating systems.

Air Duct Problems and Furnace Repair

Sunday, March 2nd, 2014

Furnace repair is sometimes not a simple process. Your home contains numerous elements that can help or hinder proper heating, but a good technician can usually deal with any component in the process that isn’t functioning as it should.  Take for example, the duct system that carries heated air from your furnace to the various rooms of your house. Air duct problems and furnace repair go hand in hand: when issues crop up in your air ducts, they invariably affect the way your furnace functions.

Air ducts carry the heated air form your furnace, which means they can affect your air en route if there are problems. The most obvious is a breach in the duct system which allows the heated air to escape and/or cooler air to enter into the ducts. Both conditions have the same effect: lowering the temperature of the heated air and forcing your furnace to work harder to compensate.

Similar issues can arise if the ducts become dented or build-up inside them reduces the air flow. Furnaces depend on a regular flow of air to raise the temperature in your house. When a blockage in the ducts reduces the flow, the furnace must again work harder: raising monthly costs and increasing the chances of a more serious breakdown in the future.

In addition, the environment around the ducts can cause problems. Say, for example, that a stretch of ducts lies in the crawlspace next to an outside wall. The cold surrounding air will cool the sides of the ducts, which will in turn cool the air inside. You can alleviate this problem by adding more insulation to the crawlspace, or by insulating the ducts directly.

Reliable heating repair services like Polar Bear Air Conditioning & Heating Inc. can help with these issues. Call us today to set up an appointment!

How Electric Ignition Works on a Gas Furnace

Tuesday, February 25th, 2014

If you installed a gas furnace for your heating in Washington, DC, instead of an electric one, it was probably because of the savings you receive using natural gas, a more economical power source than electricity. However, if you have a modern gas furnace, it still needs a small amount of electricity to run. The key electrical system in a gas furnace is the electric ignition, which we’ll examine in detail.

The two types of electronic ignition systems

Gas furnaces originally used standing pilot lights to ignite gas burners (and you’ll still find older models that use pilot lights). However, because standing pilot lights consume extra power to stay lit, they reduce furnace efficiency. The new electric ignition systems require only a small amount of electricity and do run continually. This is one of the reasons that new furnaces have higher efficiency ratings.

There are two types of electric ignition systems in gas furnaces:

  1. Furnace intermittent pilots – This system does use a pilot light; however, the pilot light comes on only when needed and an electric spark activates it. When the thermostat calls for heat, high voltage sent through the igniter causes a spark that ignites the pilot, and it supplies sufficient heat to turn on the burners. The pilot light shuts off when the burners do.
  2. Hot surface igniters –  This is the more common system, and requires no pilot light at all because the ignition generates enough heat to ignite the burners. They are made from silicon nitride or silicon carbide and operate similar to light bulbs: current passes through them and causes their surface to turn hot. A sensor detects this heat, and then opens the gas valve to send natural gas to the burners. The heat from the igniter activates the gas jets. These igniters are durable and dependable, although they will need replacement at some point during the furnace’s lifetime. Make sure you have regular maintenance for your gas furnace so your technician will know when to change the igniter.

Maintenance Is Key

Gas furnaces are safer today than ever before, and it is partially thanks to electric igniters. But don’t let your furnace go without yearly maintenance: keeping those igniters working their best is how you know your furnace is working its best. Contact Polar Bear Air Conditioning & Heating Inc. to sign up for our maintenance program for your heating in Washington, DC.

What is a Boiler Expansion Tank?

Monday, February 17th, 2014

Boilers in Washington DC are as common as forced-air furnaces: one of the pre-eminent ways we keep our homes cozy and warm in the nation’s capital. Boilers use heated water running through a series of pipes and radiators to provide heating for your home. They work extremely well in older houses which don’t have a duct system for forced-air furnaces, and also in newer houses which benefit from the comparatively simple heating process they use. The boiler’s expansion tank is a key part of that process, and it helps homeowners if they understand how it works.

In simplest terms, the boiler expansion tank helps control the pressure in the system. A boiler with too much pressure can cause a lot of problems, which makes the expansion tank an important safety feature. As the water heats up in the boiler, it expands which increases the pressure in the system. The expansion tank contains air, which unlike water, can be compressed. The air in the expansion tank thus acts as a kind of spring, absorbing the increasing pressure of the hot water without placing too much strain on the system.

Expansion tanks come in two basic types. The compression tank is a steel-walled model that uses a gauge to measure the overall pressure in the system. A bladder or diaphragm tank has a rubber bladder installed inside that can fill with water as the boiler does its job. There’s air outside the bladder on the inside of the tank to help it do its job.

Obviously whenever there’s problems with the boiler expansion tank, you need an expert to repair the damage. Trouble can come in the form of rust or a similar breach, or a damaged bladder if you’re using a bladder tank. If you own a boiler in Washington DC, then Polar Bear Air Conditioning & Heating Inc. is here to help. We can address your boiler expansion tank issues with courtesy and care, so don’t hesitate to give us a call today!

Which System Needs Fewer Repairs, a Furnace or a Boiler?

Tuesday, January 28th, 2014

Which system needs fewer repairs, a furnace or a boiler? If you’re looking to install a heater or a boiler in Alexandria, VA, that’s a pertinent question.  The answer isn’t clear cut – and specifics vary widely depending upon the quality of the system and how well it is maintained. If you look at the averages, however, boilers general tend to need fewer repairs than furnaces.

The reasons for this are simple. On the whole boilers have fewer moving parts than furnaces do, relying on water and pressure to transfer heat through the system. Furnaces, on the other hand, create hot air which is then blown through your house via a system of ducts. This requires motors, fans and other moving parts, which means greater friction on moving parts and greater wear and tear. Granted, the heat required for the boiler to function exacts a toll on its own, but on the whole, boilers tend to last much longer before breaking down.

That translates to a longer life in general for boilers than for furnaces. However, boilers tend to me more expensive to install, and you can’t use your radiators for cooling in the summer. However, you can easily use the duct system of your furnace with a central air conditioning system to cool your home during the hotter months. Remember to talk to an HVAC contractor about what you want from your system, and they can help you determine which heater is right for your needs.

Regardless of the system you select, you’re going to need a qualified service provider to do the job right.  If you need furnace or boiler service in Alexandria, VA, call on Polar Bear Air Conditioning & Heating Inc. We have the training, experience and personnel to do the job right the first time every time.  Contact us today to make an appointment!

Repair or Replace Your Existing Heating System

Tuesday, January 21st, 2014

Heating systems are designed to be run for many years, but sooner or later, you need to face the reality that a new system is necessary. You will have to decide whether you should repair or replace your existing heating system. It’s typically a case by case situation and you’ll need to decide for yourself it it’s worth it to repair a given system or simply install a new one. If you need any help with furnace repair in Arlington, VA, give Polar Bear Air Conditioning & Heating, Inc. a call.

That decision usually boils down to money, and how much you’ve spent on your existing heating system. If repair bills keep piling up and/or you’re dealing with a major cost to a given repair, you might prefer to consider a new system rather than sending good money after bad. Similarly, a furnace that has suffered from overall wear and tear might be due for a replacement, even if you don’t have any specific repairs. An inefficient heater with a lot of worn parts will use a lot more energy than it should to keep your home comfortable. As the months go by, those extra costs will add up until a newer, more efficient heater is really the only viable option.

Those issues can be compounded by the age of the system. In and of itself, an old heater doesn’t necessarily merit any replacement. If it’s functioning properly and you’ve kept it well maintained over the years, it can last well beyond its normal expiration date. On the other hand, if your heater is more than ten years old and you have to repair it a lot, or if it’s using more energy from month to month than it should, then its advanced age may be the final factor in deciding to install a new unit.

When asking whether to repair or replace your existing heating system, you can count on the experts at Polar Bear Air Conditioning & Heating, Inc. for advice. We handle furnace repair in Arlington, VA and we can help determine if your old unit is worth save or if a new one might be best. Give us a call to set up a consultation today. You’ll be glad that you did!

When to Stop Repairing Your Furnace and Replace It

Tuesday, January 14th, 2014

Our furnaces are usually things we rely on more than we think about. As long as you schedule regular maintenance, your furnace should last a good long time. Sooner or later, however, you’re going to need to put your old furnace out to pasture. Deciding when to do that can be tough, especially since buying a new furnace is a sizable investment. Here’s when to stop repairing your furnace and replace it.

The biggest sign of serious problems with your furnace stem from costs. If you find yourself calling a repair service more often than you’d like, or if the repairs are starting to add up, you may want to think about a replacement furnace. In addition, as furnaces get older, they must work harder to do their jobs, which means that your monthly heating bills may go up even if you aren’t using the furnace more often than usual.  Things may get so expensive that the monthly savings of a new unit outweigh the potential costs.

Then there’s the potential that a new system offers. Not only will it likely be a more effective unit than your old one, but it may offer options such as a variable speed fans, which can help you save energy.

All of that can be compounded by the age of the furnace. If yours is older than ten years and experiencing problems, it’s a good sign that you’ll need to think about a new one.

If you need Washington DC furnace repair service, call Polar Bear Air Conditioning, Inc. We can help you determine when it’s time to replace your furnace, and help you pick the right system for your home. Pick up the phone and give us a call today!
