3 Signs you Need Air Conditioning Repair

Whether your home just isn’t getting cool enough or you hear strange noises coming from your HVAC system, your air conditioner could be to blame. Recognizing these common signs of trouble can help you identify the problem and know when to call for help with your air conditioning system:

Your air conditioner is making noises.

If your previously quiet home is now full of wheezing, whining or humming, it could be a sign that you need to have your air conditioner repaired. Noises can be the first sign of trouble, and having your unit checked out right away can prevent further damage.

You notice strange odors or excess moisture.

If your home suddenly has a mildew smell or you see condensation or moisture, then your air conditioner could be the issue. A professional can check out your unit to ensure it is working – or find out if it is the source of the moisture.

Any of the above signs is a clear indication that your air conditioner is in trouble; the sooner you call for help, the better. Contact us at Cunningham Associates to take care of your air conditioner so that your home can then be returned to its normal and comfortable state.

What Whole-House Ventilation Can Do for You

Many of today’s homes lack proper ventilation, which can lead to stale and unhealthy air. As a result, some individuals suffer from allergies and other health problems brought on by poor indoor air quality.

Your air conditioner does a great job of cooling air and removing circulating particles, however, alone, it isn’t always enough to renew your home’s air. That’s why you should consider installing a whole-house ventilation system.

A whole-house ventilation system overcomes the lack of proper air circulation experienced by many homeowners. There are three whole-house systems in widespread use, and each of these are described below.

Exhaust Ventilation Systems

An exhaust ventilation system works by using a roof-mounted exhaust fan to suck air from the interior of a home and blow it outside. This causes fresh air to be pulled through the microscopic pores and crevices in the sides of a home.

As a result, air moves across, up and out of a home. Exhaust ventilation systems work well in drier, cooler climates. However, they are not ideal for humid areas where moist air can be pulled through walls, causing condensation inside the insulation and between drywall panels.

Supply Ventilation Systems

Supply ventilation systems work in an opposite manner from exhaust ventilation systems. Instead of pulling air through a roof-mounted vent, supply systems pump air into the home; this  forces air through the walls from the inside to the outside.

Supply systems have some advantages over exhaust systems, such as the ability to filter incoming air through the roof-mounted supply fan. However, during winter, supply systems can create drafty conditions and potentially interfere with indoor heating.

Balanced Ventilation Systems

A balanced whole-house ventilation system is the best solution, since it takes elements from both types of whole-house systems and combines them. A balanced system uses both exhaust and supply fans to provide an even mixing of air inside the home, which can mitigate some of the disadvantages associated with both of the other options.

Avoid Serious Health Problems by Working with a Heating Contractor

Many problems can arise with heating in your home and it is not one of those things you can choose to ignore. At best, not having sufficient heat will make you and your family uncomfortable. Then again, in the worst-case scenario, it can lead to serious health problems.

Problems That Arise with a Lack of Heating

Not having sufficient heat can lead to someone getting sick. When you catch a chill due to a lack of heating in the home, it can lead into a long-term illness.

Plus, not having sufficient heat also means that you might end up buying a number of space heaters which will run up your electricity bill.

People have also been known to do senseless things like turning on the oven and leaving it open in order to make the house warmer. This is very dangerous as the gas can spread throughout the house and cause an explosion. Even if there is no explosion, you and your loved ones might inhale a lot of gas which is terrible for your health.

Therefore it’s very important to have your heating working properly. This will protect you and your loved ones in the long run.

Advantages of Working with the Same Heating Contractor

The best thing is to have a heating contractor on speed dial so that you can request service for your heating problems and get everything take care of as soon as possible. It’s a good idea to use the same person no matter what problems you might have. Once you’ve worked with a heating contractor and you know that they do a good job, you can keep working with them.

The advantage of this is that the contractor will understand your heating system inside and out. So when you call them with a problem, they’ll probably already have the solution. This saves time and money in the long run.

We encourage you to reach out to us at Cunningham Associates with any questions or service needs you might have.

How to Incorporate Heating Into Your Room Addition

Changing up your floorplan is an increasingly common project. You might want an extra room. Or, maybe that garage would work better as a study. Even expanding an existing room needs a lot of planning and groundwork. Don’t let air conditioning get lost along the way. Keep these three heating considerations in mind when starting to build:

Will the new space have adequate ventilation?

Houses have a lot of invisible ventilation. Brick walls aren’t solid: they have minute gaps in the grout to allow for air flow during contraction and expansion. Every roof is ringed with a series of vents that let air escape from your attic, and that’s not even considering the (at least two) attic fans your house should have closer to the peak of your roof. Make sure your contractor has accounted for air flow in your new space, especially if you have gas appliances or use a furnace.

Can your HVAC handle the new load?

Heating systems are designed around the square footage they have to keep warm. Even knocking down a wall or changing the floor plan without incorporating new area can make your existing HVAC less effective. Have an expert check that your heater can fully heat the new space without impacting its effectiveness throughout the rest of the house.

Who is making the HVAC changes?

General contractors generally aren’t licensed to install, repair, or modify heating and HVAC systems. Double check that your contractor is bringing in expert professionals who are certified to make the changes you need. It might be more expensive upfront, but it will save you a lot in time, money, and stress over the years.

The Benefits New Heating Installation Could Provide You With This Winter

By now there have been enough cold days this season that you likely have a good idea as to whether or not your furnace may need replacing this winter. However, if you have yet to have your furnace replaced, either due to the cost of replacement or due to the fact that you do not want to deal with the stress of having your HVAC system replaced, you may be surprised to learn how beneficial having your furnace replaced can be. If your aging furnace has been struggling to keep up with the needs of you and your family, here are just a few of the benefits of having it replaced this winter.

Boost Efficiency

If your furnace is 15-20 years old or older, you may not realize how inefficient your system is, and you may be surprised to discover how much money a new furnace could save you. A new furnace will be much more energy-efficient, which will help to greatly reduce the cost of heating your home this winter.

Benefit From a Programmable Thermostat

If your furnace is 20 years old, then you may not have a programmable thermostat. A high-efficiency HVAC system will come with a state-of-the-art programmable thermostat that will give you the ability to not only program your system to turn on and off at specific times, but also, systems with specific zones will allow you to heat certain rooms independently from the rest of your home. This will give you unprecedented control over how and when you heat your home, helping to further save you money on your energy bills.

Breathe Easier

If your furnace is 20 years old, you may be surprised by how much dirt, debris, and allergens have been collecting in your unit and your ductwork over the years. These irritants are then spread throughout your home when you run your furnace leading to increased allergy symptoms and other respiratory problems for you and your family. By replacing your aging furnace you will be helping to make the air in your home more breathable year-round.

3 Reasons to Schedule a Furnace Tune-Up Before Winter Hits

November weather means turning on your furnace for a long winter. If the first cold snap hasn’t hit your local area yet, then now is the best time to get your furnace serviced. Here’s why:

  • The beginning of winter is a busy season for heating contractors and furnace repair companies, which could delay your repair. You don’t want to wait until after the first big storm to get your furnace serviced. Not only can that leave your home without heat during the following low temperatures, a long delay can damage your heating system more or even be dangerous if you have a gas-powered furnace.
  • Servicing your system can help solve problems before they start. Small malfunctions and inefficiencies build up over time, and getting your HVAC checked before you use it regularly can help you catch those problems before your system breaks. Having your furnace serviced means a trained professional checks your ventilation, gas and power connections, and the internal cooling system, which saves you money on larger, preventable repairs.
  • Tune-ups help your home’s air quality. Any air conditioning system in your home collects dust and debris as it circulates air. While changing the filter is one of the best steps you can take to ensuring that allergens are removed from the air and your system isn’t overworking due to poor ventilation, sometimes it’s not enough. Dust can build up in the internal workings of your furnace and mildew that may have built up during the furnace’s dormant season needs to be removed.

Scheduling a tune-up for your furnace before the busy winter season not only helps ensure the system will run once the weather turns, it helps keep your furnace running efficiently. So, contact Cunningham Associates to set up a time to schedule a tune-up.

Making Indoor Heating Systems More Effective

Many people are making their heating systems less effective during the colder months without even realizing it. People who try to find ways to save energy around the house will certainly spend less money on heating in general. However, heating systems in these households will tend to last longer as well.

1. Install energy-efficient windows.

There are lots of energy-efficient windows on the market today. Certain types of windows are much better at providing adequate insulation. As such, people won’t lose as much of the heat that they’re paying for in the first place.

2. Leave as many interior doors open as possible.

Many people are told to close their interior doors in order to make the heating systems work more effectively. However, keeping all of the interior doors closed will just interfere with the airflow between rooms.

In fact, people might end up spending more money on energy during the winter if they constantly keep all of the interior doors closed, regardless of what they’ve been told. The air quality of all rooms will also improve in the process of leaving the doors open.

3. Make sure the floor stays insulated.

Lots of people forget to make sure that their floors are insulated. In fact, a household can lose as much as ten percent of its heat through the floor. People who have carpeted floors might not have to worry about this as much. Placing blankets and rugs on hardwood floors can make a big difference for the people who are trying to conserve as much heat as possible indoors.

Indoor heating systems will be more effective and efficient if people counteract some of the heat loss that can occur throughout a household. Give Cunningham Associates a call with any questions or HVAC service needs you may have – we are happy to help!

 

Short Cycling Furnace Causes: Dirty Flame Rod

Ever wonder what causes a cycling in a furnace? We encourage you to read this article to learn how a dirty flame rod can lead to short cycling.

The Flame Rod 

The flame rod is part of a furnace’s built-in safety system. Its job is to help regulate the state of the gas valve. The idea is that, when ignition is successful, the burner flames will heat up the flame rod, causing it to send a signal to keep the gas valve open. If, however, combustion does not occur, the cold flame rod will soon shut down the gas valve, thus keeping raw gas from leaking out.

Problems 

This is all well and good–so long as the flame rod can do its job correctly. The problem is that, over time, contaminants build up on the surface of the rod. Such contaminants hamper its ability to detect heat. Eventually they will keep it from being able to do its job at all, meaning that the rod, failing to detect heat, will close the gas valve down even when combustion is occurring.

Fortunately, a furnace technician can often resolve this issue simply by giving the flame rod a thorough cleaning with sandpaper or steel wool. If your furnace has been short cycling, it is important to have your flame rod inspected as soon as possible.

Air Conditioning Contractor Explains Why Your AC Keeps Tripping the Circuit Breaker

A circuit breaker protects your electrical system and the electric devices in your home from excessive electrical current. Too much electrical current can damage your air conditioning system and heat up wiring to the point of causing a fire. This is why you should never continually reset a circuit breaker every time it trips.

Now and then a one-time power surge may trip the circuit breaker, such as from a lightning storm. To rule this out, reset your circuit breaker only once before turning your air conditioner on. If the breaker trips again, there’s a problem with either your circuit breaker or the AC system. If the breaker has a burning smell, feels hot, or you see signs of charring, the circuit breaker has gone bad. Otherwise, the issue probably lies with your air conditioner.

Here are four possible problems with your AC:

  • The air filter is dirty. A dirty air filter increases resistance to air flowing through it which then intensifies the workload on your AC system, which ultimately increases the draw of electrical current. This increased current trips the circuit breaker. Replace the air filter and try again.
  • The condenser unit requires cleaning. The condenser unit can get full of dirt and debris, especially in its fins. This reduces air flow through the fins and prevents the condenser from efficiently dispersing heat. The AC then draws too much current, which trips the circuit breaker. If the condenser is dirty and you have experience cleaning the condenser unit, then give it a good cleaning.
  • A motor has a problem. A motor could have shorted out from running too hot. For example, if a fan motor is working too hard to push air, the internal wiring could overheat and break down the insulation; thus causing a short, which trips the breaker. The motor having a bad capacitor can also trip the circuit breaker.
  • The air conditioner has a refrigerant leak. Too little refrigerant causes the AC system to work too hard. If this is the problem, there is no point in refilling your AC with more refrigerant. The fact that your AC worked without problems in the past means that it used to have plenty of refrigerant; which means that your AC has a leak and should be fixed.
