The importance of getting your HVAC system serviced annually

Almost all manufacturers of HVAC systems recommend that you get your unit serviced and inspected at yearly intervals. However, a lot of us overlook this necessity and miss out on service for longer durations of time, either because of forgetfulness or cost issues. Skipping on yearly service on your HVAC system can have several side effects such as- spending more on energy bills and putting the health and safety of your family at risk. A certified HVAC service technician will ensure your unit is operating correctly and at its best efficiency - which will help you save a lot of money in the long run.

Checking for dangerous leaks:

In case you own a natural gas or oil furnace, your unit will burn fossil fuel. When fossil fuels burn they produce a dangerous bi-product known as carbon monoxide. A service technician will ensure that there is no risk of this deadly byproduct being emitted from your furnace. Even small leaks can be dangerous, so a yearly service inspection to look for the lethal poisonous gas is advised.

An HVAC expert ensures that your unit is operating correctly and is clean of dust, dirt, debris and other similar materials that can catch fire easily. One of the biggest benefits of having an HVAC system serviced yearly is maximizing its efficiency. Fuel that goes into these units is expensive, so making sure your system is burning it at an effective rate is related directly to the money you will have to spend on your energy bills. An HVAC service technician will know how to adjust your furnace to make sure it is operating at its best efficiency. "Tune ups" and inspections will lead to lower bills and less fuel consumption.

Preventive maintenance:

Having your system serviced on a yearly basis is a great way to perform preventative maintenance. It is advised that annual service should be performed before the winter months to make sure the furnace will work effectively throughout the season. A lot of times, an HVAC service provider will catch potential problems before they arise and offer preventive solutions in the form of replacement of parts or repair. This can be highly beneficial to homeowners who will not have to undergo the struggle of having their unit break down in the cold winters, leaving their loved ones with no heat for days or weeks till it can finally be repaired.

The benefits of having a furnace serviced and inspected by a professional technician are several. You will be able to save a lot of money on your energy bills and fuel costs, and have peace of mind that the furnace will operate properly on even the coolest of winter days. One of the best ways to look for a good service provider is to search online. The internet offers plethora of options for you to choose from. Once you find the right engineer to service and inspect your HVAC on an annual basis you can rest assured that your HVAC unit will operate safely and at the best efficiency.

Can your HVAC system decrease your home air quality?

Dirt, dust and debris have a tendency to get accumulated within the air ducts of your HVAC if you do not clean them regularly. They become breeding grounds of dangerous fungi and bacteria that may cause problems such as allergies, asthma, and respiratory problems.

So, to ensure respectable indoor air quality, you must clean the air ducts regularly and thoroughly.

When is the right time to clean the HVAC system?

Whether you perform the cleaning yourself or take the help of a professional, you should know when your air conditioning system needs cleaning. Here are a few signs that indicate towards an unclean HVAC machine:

1.Noticeable mold growth within the ducts

Mold is essentially a fungal growth that gradually spreads within the hard surface of the HVAC system. By cleaning regularly, you can remove the growth of molds. But, if the molds get accumulated over a period of time, your HVAC will require professional cleaning. 

2.Ducts congested with debris and dust

When the ducts in the HVAC system are blocked with debris and dust, you are likely to inhale unhealthy air that may lead to health issues. Moreover, your system will also become less efficient in terms of performance.

Although you can clean the small debris on your own, for tougher molds, debris or clogs, you will need professional help, as HVAC cleaning companies use EPA approved sanitizers to apply on the problem areas.

How to choose a HVAC cleaning company?

After inspecting the condition of the system, if you decide to hire a professional, you must speak to at least three cleaning companies. Verify if they have proper accreditation and licenses. By doing this, you can rest assured that you have selected a knowledgeable, responsible and reliable service provider who knows how to do his job well.

Another way to short list a good service provider is to ask for recommendations from friends and family. You can even call your neighbor to find out which company does the best job within your area.

Precautions you can take to minimize contamination of ducts

Oftentimes air ducts within the HVAC system collect significant amounts of dust, debris and dirt particles that end up contaminating the air. Hence, it is important to minimize contamination by stopping dirt from entering the system. For this, you need to ensure the following:

1.Make use of efficient air filters and make sure you change them on a regular basis
2.In case of damage or leakage, get it corrected
3.Make sure there is no moisture present in the system
4.Clean the drain pans and cooling coils by a professional cleaning service
5.Make sure there are no missing filters
6.In case any renovation or construction work is being carried out, seal the air ducts, so that debris and dust don’t enter the machine

Most AC contractors advise on having your heating/cooling system checked twice a year. The whole system should be flushed out of unwanted stuff that gets accumulated. Ductwork also should be cleaned thoroughly. Such cleaning is recommended to ensure that the HVAC systems are operating at optimal levels so that the desired air quality in your house is maintained.

Tips for hiring an HVAC specialist

When your ventilation, heating, or air conditioning system needs to be repaired or replaced, you will probably have to hire an HVAC expert who has the license and specialization to work on the unit. It is important for the contractor to be properly insured, trained, and have certifications that conform to professional HVAC procedures, in addition to other qualifications.

Here are some tips to keep in mind when choosing an HVAC specialist.

1. Ask your friends, family or neighbors for referrals.
   
   Start your search by asking for advice from family and friends. Also, while requesting other people for referrals, make sure you ask them for the reason that required them to hire the HVAC expert in the first place. This should give you a better idea of whether the specific contractor will suit your needs or not. Apart from this, you can also search the local business directories for customer reviews. Do not make the mistake of choosing a specialist based only on an attractive website.


2. Find out if the HVAC candidate has the certifications and licenses needed by the state or local area in which you live.
   
   If you don’t know about the certifications and licenses HVAC specialists are required to have, you can contact a government representative or official from your state or local area. You can also search online to find out about the licenses required in every state and also to confirm the authenticity of the licenses of a particular contractor.
   


3. Verify whether the specialist has low volume of negative reviews and a decent rating in your local area.
   
   Visit the BBB website to research about the shortlisted HVAC contractors. You can also get in touch with the council of BBB for information on specific specialists or businesses.
   


4. The specialists should have insurance.
   
   You should make sure the expert has worker's compensation insurance. If you let anyone work inside your premises and perform maintenances you become responsible for the cost of any damage or injury that may occur, even accidentally. But if you hire someone with a liability or worker’s compensation insurance you do not risk incidental damage of any kind.
   


5. Choose an expert who is ready to inspect the system in your house before offering estimates or starting the repairs.
   
   HVAC specialists must measure air flow, inspect insulation and look for air leaks to make sure all components comply with the HVAC guidelines and the specifications laid down by the manufacturer before providing an estimate or starting the work.
   


6. Get bids from at least three HVAC specialists to compare pricing and work before making your final decision.
   
   Some of the factors that should be taken into consideration when obtaining bids apart from the overall cost are installations to be done, energy savings during the repair work and the warranties offered.
   

As the technologies supporting the HVAC systems advance to newer levels, repairing these units has become all the more difficult for unlicensed individuals. This is particularly true now that so many machines have smart thermostats and other complex pieces of electronics. Hence, it is best to save money by hiring the right professional. Keep the aforementioned tips in mind and you will have no problem shortlisting a skilled and competent service provider.

Tips to find a good central heating expert

Installing a central heating system can be a huge commitment. Since its expensive and an important part of your home, it should not be taken lightly. When looking for someone to install the new machine, you'll want to ensure that you are choosing the right provider. One of the most important factors to consider is the reputation and reliability. If a company is unreliable or suffers from a bad reputation, chances are they will not be able to offer the desired level of service that should be provided to someone investing in a heating system.

Knowledge:

An experienced and skilled HVAC expert will always be aware of the heating methods (such as, broilers vs. furnace, energy efficiency, and the like) in use. They will be able to provide advice regarding any feature of the central heating system. If a person is not well-versed with the functioning and components of a central heating system, then you are unlikely to receive top rate installations or service.

Ask around:

There are numerous companies that focus on this type of installation. Ask your family and neighbors about who they used and their experience. You should also perform an online research to find out what the general opinion about a company is and whether they are affiliated to Better Business Bureau. All these factors should help you figure out who you'd like to call to discuss further.

Extra features:

Another option to discuss with an expert is the programmable thermostat. This feature can help you save several dollars on energy bills. It's an easy to install equipment with minimal costs, and allows you to modify the settings of your thermostat for specific temperatures at certain times all through the day. For instance, you can program the thermostat to automatically turn-off during the day, and to switch on an hour before you come home so that your house is warm when you arrive.

Central heating is certainly the most effective and efficient way of heating, as it changes the temperature of the entire house rather than attempting to heat small parts of the house. Also, since you have the facility to regulate your thermostat, you can control the amount of money you spend on heating. However, the central heating professional you hire should be able to install the machine correctly and should be able to give you tips on how to run your system in an optimized manner for utmost efficiency. They must required for two-level or bigger homes that will need separate units for different parts of the house. The experts should also advise you on the most cost-efficient central heating systems available in the market so that you get the most out of your investment.

What does installation of central heating system involve?

Central heating helps in maintaining a comfortable temperature inside the house with only minor variations in heating from room to room. The system gets rid of the unpleasant floor or wall-mounted heaters. Although installation of central heating should be left to a professional, with few simple tools, you can also do it yourself.

How is central heating installed?

Create a blueprint:

The first step involves deciding where the ducting will run with the help of an updated plan of the house. The most important thing to see is if the house has a cellar or an attic. If the house has both, you will have to decide between the floors or ceilings to create vent openings.

The next step involves cutting out vent openings in the ceiling or floor and installing duct openings.

Ducts:

Decide where the air handler and furnace will go and mount them as per the instructions provided by the manufacturer. Move the ducting to the farthest opening from the furnace. 

Also, mount a Y-pipe for every duct opening. Add a second Y-pipe to make two close openings in rooms. Fit hard ducting within a couple of feet of the duct opening and link it with flexible ducting. Repeat the process for each duct opening. If required, cover the main duct with a cap.

Make sure all ducting connections are secure by installing three self-tapping screws around every connection. Coat the connection and screw location liberally with sealing putty.

Thermostat

Direct a 20 gauge cable from the furnace to the location where you wish to mount your thermostat. Connect all the wires at both the ends as per installation instructions for every unit. Thermostat connections will require a screwdriver, while connections at the furnace-side may require twisting together the two wires and securing them with wire nuts or screw blocks.

Rout 12-2:

Direct a 12-2 wire from the air handler and furnace to the electrical breaker/ fuse panel. Connect white to white and black to black. Twist the wire nuts securely onto both the connections. You will also have to fix the bare wire to a secure ground.

The last step involves connecting all the wires to the electrical panel and getting the heating unit ready. This stage involves moving fuses and breakers for balancing the electrical load. 

Although it is possible to install central heating on your own, it is best to leave the technicalities to professionals. The installation of the system is complex and requires technical know-how. There are several expert HVAC installation and maintenance companies out these who can help you with your system and ensure it works seamlessly all season long.

Five most common central heating problems

Having a central heating system is no longer a luxury. For those who live in cold climates, central heating system is a necessity to survive the chilly winter cold. However, installing a quality system isn’t enough, it is also important to make sure your machine remains in good shape the whole year round. By performing regular maintenance, you will be able to avoid costly maintenance charges and a cold house during unbearable winters.

Once you’re aware of the top five problems related to central heating, you will be in perfect position to keep your home comfortable and warm. 

1. Complete heat loss - If switching on your furnace gives absolutely no response, the first thing you must do is isolate the issue – try to analyze where the problem lies. In case the system isn’t getting enough electrical power, it is best to call an electrician. Check out the pilot light. If it’s not igniting, the problem probably lies with the gas supply. You will have to call the gas supplier to tackle this issue. Also, check if the thermostat is “on” and the temperature is high enough to trigger the furnace.
2. Partial heat loss - If your furnace is giving out heat but is not operating at its best efficiency, you may have different problems going on. It is a possibility that your ductwork system is suffering from blockages or leaks. In case you have radiators, it is also possible that the radiators require bleeding to get rid of trapped air.
3. Problem with the ductwork system - Since ductwork is used extensively throughout the house, there can be several blockages due to insects or rodents. A blockage in the ductwork will normally require the services of a professional, who can analyze and fix the problem. Leaks in ductwork, leading to evasion of heat from the ducts also necessitates expert service to mend.
4. Pilot light issues - It is important for the pilot light to be lit continuously for the furnace to work efficiently. If you check the light and it is not lit, you will have to reignite it. In case you see the pilot light is set to “on”, test its strength. The flame has to be blue and strong – not weak and yellow. A weak pilot light can be extremely dangerous, leading to high levels of fatal carbon monoxide. It is best to call a professional if you ever face pilot light issues. 
5. Broken Thermostat - If you observe that your thermostat is malfunctioning, with freezing temperatures one minute and high temperatures soon after, then the thermostat is probably broken. This can cause the machine to misread the real temperature of the room and fail to run properly. It is best to call a professional to recalibrate the thermostat. In case the device is beyond repair, consider getting it replaced.

You may not be able to handle central heating problems on your own; you can certainly diagnose and get a professional to perform the repairs. Use information available over the internet to troubleshoot the furnace. It is also a good idea to call up experienced central heating maintenance providers for professional assistance. 

Water leakage in an Air-Conditioner

A fully functional air conditioner is the most desirable gadget that every household needs during summer. Sometimes even the small cooling issues can lead to big problems forcing you to compromise on cost and comfort levels during hot, sultry days.

One of the most annoying problems that you may encounter with an air conditioner is the dreaded water leak. A water seepage from the air conditioning system can be challenging indeed and difficult to diagnose. It can have multiple root causes and several solutions. This article focuses on few basic things to be considered if there is a water leak noticed in the air conditioning unit.

Main reasons for water leakage in an air-conditioner:

• Faulty pump: The most recurring cause for water leak in an air conditioner is a faulty condenser pump. The main job of this pump is to drive water out of your house. This is the water that is removed from room air by your air conditioning unit. Due to constant presence of water in the pump, it may get clogged and its capacity to pump water may get hindered. This can be tested by pouring water in the condenser pan to see if it can properly pump out excess water.
• Clogged drain line: There is a drain hole in an air conditioner for the wasted water to be driven out. Over time, dirt gets accumulated that may mix with water thereby clogging the drain pipe. Since water flow in the drain pipe becomes restricted due to congestion, water starts leaking through the main unit. By identifying the exit pipe for your drain, the water leak problem can be solved.
• Improper installation: When the main air conditioning unit and drains are not properly installed, it can cause several problems, including water leakage. A window air conditioner must be installed so that it is slightly lower at the rear than the front. This allows easy removal of water from the room towards back of the machine. If installed too low at the front, this water flows into the room rather than moving outside.
• A frozen coil: If airflow is impeded due to extensive use of the air conditioner, frost can form on the evaporator coil which eventually melts thus causing water seepage. The first thing to check in such a scenario is the air conditioner filter. If filters are clogged, air flow to the system is blocked and ice may form on the coil. Even the intake registers need to be checked to ensure that nothing is blocking the air flow into the system. Turning off the unit for a few hours every few days to allow the ice to melt may prove to be a feasible solution.
• A worn-out insulation coil: The insulation coil, at the back of the main unit is responsible for soaking up condensation that is formed on the copper wire. Due to daily wear and tear, this coil may not function properly, thereby causing water to leak from the back of the unit.

Final word of advice, do contact a reliable HVAC technician to ensure professional handling of the water leakage issue.
