What are signs that my AC needs a tune-up?

Signs that Your AC Needs a Tuneup


AC Tune-UpWhile your air conditioner is a great thing to have and a great way to stay cool in the summer, there are things that can occasionally go wrong with it. Aside from regular repairs that could be the result of something not working, you may need an AC tune up. There are a few signs that you should look for that will tell you whether or not it is time for you to tune up your air conditioner.

Not as Cold

When your air conditioner is not running as cold as it should be, but is still working, it might mean that you need to have it tuned up. If you notice a major difference in temperature, you probably need it repaired. A slight difference or air that is not blowing ice cold simply means you should have a tune up.

Running Harder

Have you ever noticed that your air conditioner is making more noise or seems to be struggling harder than it should be to cool down your house? When this happens, it usually means that you should get your air conditioner tuned up. Make sure that you pay close attention to how your air conditioner runs normally so you can have an idea if it needs tuned up.

After Time

If it has been a while since your last tune up, you probably need to have your air conditioner checked on and tuned up. Even if there is nothing wrong with it, it’s ice cold and it is not making any strange noises, you should consider having it tuned up. This will ensure that your air conditioner will run properly for a long time and it will enable you to spend less money on more costly air conditioner repairs in the future.

When you have an air conditioner, just like any major appliance, you must perform regular maintenance. This includes having it tuned up on a regular basis. Make sure you know the signs to look out for when you need it tuned up and get it done as quickly as possible when you notice the signs.

How should I choose an HVAC technician?

Choosing an HVAC contractor

HVACThere’s nothing worse than having your heating or air conditioning go out, and it always seems to happen at the worst possible time. It’s important that you do your research on local companies before you let someone come in to your home and work on your air conditioning system. Most people are unaware of what qualities make a good HVAC company. I want to give you an insight into these qualities so that you can make the best educated decision for your needs and avoid further problems later on. There is nothing more powerful and reassuring than word of mouth. Talk to your friends and see if they have had any experience with HVAC contractors in your area. If you do not have any friends with helpful knowledge try looking at business review websites and read what costumers have said about their experiences. After you have some candidates in mind you should verify that they have the proper licenses and certifications for your local area.

Never assume that someone who is offering their services is properly licensed. During a repair there are many things that can happen. It’s important that the contractor you are using has insurance to protect both themselves as well as you in the event of an accident. Any reputable company will be willing to come out and do an inspection of your problem free of charge before determining cost and making a repair appointment.

After the inspection, get an estimate on paper as well as estimates from a few other companies so that you can get the most competitive rate in your area. Using these steps when searching for a HVAC contractor will help keep you safe and insure that the job is done to the highest degree possible while keeping you from being over charged for services. Always remember that knowledge is power and you, the consumer, must be protected when any services are provided.

What does the SEER rating mean on an AC unit?

What Does the SEER Rating Mean on an AC Unit?


AC UnitConsumers are constantly trying to make educated decisions and use all types of information available to them. The Internet, commercial and industry magazines, and consumer ratings are all helpful tools that lead buyers in one direction or another. Sometimes all the information can actually be more of a hindrance than a help as the details and overwhelming data become difficult to understand or sort through and prioritize. There are some simple ways to help consumers make the decision that is best for their specific needs based on the items available and the intended use.

One of the most important factors to understand about product labels is the energy efficiency ratings. Since most consumers are interested in reducing both their carbon footprint and their utility bills, these labels seem to target specific, environmentally conscious buyers. Aside from the yellow Energy Saver labels, the most recognized labels on an AC unit is the SEER rating. Both are important to understand for the purpose of consumption and overall utility costs, but they have very different perspectives and give information based on two different arenas.

The Energy Saver rating is basically an estimate of how much the unit will cost to operate. This abstract number is based on the cost of energy but does not necessarily incorporate family size, approximate usage, or other factors that could affect the price of electricity and other utilities. The SEER rating is used to differentiate the efficiency of AC units based on their Seasonal Energy Efficiency Ratio (hence the acronym). This number is more specific to both the unit and the intended usage. Since an AC unit is only used for one purpose, to cool a specific area, it is easier to measure the output cost based on real data.

Generally speaking, the higher the SEER number, the higher the energy efficiency of the AC unit. Since each unit is expected to last for at least ten years, purchasing a unit today will likely save homeowners quite a bit of money because newer units will be at least 10%-30% more efficient than the units they are replacing.

Why should I install a digital setback thermostat?

Benefits of Having A Digital Setback Thermostat


ThermostatThe bitter cold of winter and the sweltering heat of summer can put quite the strain on home heating and cooling costs. You want to be comfortable without breaking the bank. Installing a digital setback thermostat can help ease some of these costs.

A digital setback thermostat is a programmable thermostat that adjusts the temperature of a home (or business) according to a series of programmed settings that go into effect at various times of the day. They are designed for people who live on a fixed schedule, such as leaving and coming home from work at the same time each day. A digital setback thermostat reduces heating/cooling losses by allowing the temperature differences to be reduced at times when the amount of heating or cooling would not be noticed. For example, you leave for work in the morning and come home eight hours later. While you are gone, your home may be running its furnace or air conditioning while no one is there to reap the benefits, thus racking up a high heating/cooling bill. With a digital setback thermostat, units are programmed to kick on only at select times, such as when a family is due home from work and school. Digital setback thermostats can also be programmed to fit around sleep schedules.

Newer homes are often equipped with digital setback thermostats, but upgrading to one is easy to do either by yourself or by hiring a trusted HVAC specialist. To get the most out of your investment, the thermostat should be installed on an interior wall away from elements that can influence readings, such as direct sunlight, skylights, drafts, doorways, and windows. Be sure your thermostat is easily accessible for easy programming and is not blocked by furniture. When programming, take into account bedtimes and waking up times of household members and the peak times your home is occupied. Adjust the thermostat for times in which the house in unoccupied for more than four hours.

A digital setback thermostat makes your London home comfortable  while reducing energy costs. Considering installing one? Call City Gas Services today at 020 8882 2266. 

What are the benefits of having a programmable thermostat?

Benefits of Having a Programmable Thermostat


Programmable ThermostatThe use of programmable thermostats has become extremely popular over the last few years due to their ability to provide consumers with more accurate, more convenient, and more affordable personal comfort by using preset temperature levels.

Regardless of your lifestyle, programmable thermostats can be very beneficial to you and your family. If you work outside of the home, or are gone for hours at a time, you can set your programmable thermostat accordingly while you are away, and set it to return to your preferred comfort level shortly before you return. If you are at home most of the day and night, you can set your programmable thermostat to regulate the temperature of your home according to your activity levels throughout the day, etc. For example, you may wish to reduce heating or cooling during periods while you are asleep, but return to normal comfort levels when you awaken.

As a bonus, the settings on these devices can be manually changed to override the automatic presets if needed. If you are using the oven, for instance, you may wish to manually override your presets while the oven is in use to conserve energy or better regulate the temperature in your home.

Not only are these thermostats much more convenient, but they are typically more accurate than manual thermostats as well. A programmable thermostat typically offers more setting options and more precise temperature management for a multitude of programming choices. Additionally, your programmable thermostat can be programmed to repeat various settings each day, or to rotate stored settings on various days at your preference.

By giving the homeowner the ability to set automatic temperatures according to various factors, programmable thermostats can save enormous amounts of energy, and some of your hard earned cash as well. Most homeowners will notice a substantial reduction on their utility bill within the first year of properly employing a programmable thermostat.

For those homeowners who are environmentally conscious, this device is a very attractive option. The programmable thermostat contains no mercury and is considered eco-friendly as well. In addition, the use of less energy reduces greenhouse gas emissions that are associated with high energy production.

How often should I check my heater’s gas pressure?

The Importance of Gas Pressure in Heating Units


London Heating EngineerBeing a homeowner is one of the most enjoyable things a person can be. Unfortunately, it can also be one of the most stressful when something in the home goes wrong. But, with proper maintenance and care the stress never has to happen! One of these important preventative actions is to check the gas pressure in your home’s heating unit. While this might sound complicated, in reality this is quite simple.

Every heating unit, no matter its make or model, comes equipped with a mechanism to regulate the gas pressure within. This mechanism needs to be checked periodically to make sure that the pressure is at the required level. Gas pressure can be either too high or too low, but whether it’s one or the other still ruins the operations of the machine. Proper pressure is needed to ensure that fuel actually reaches the gas lines to power the unit. If pressure is simply too low, then the heating unit will not work, probably at all. But, if the pressure is actually too high, the machine has a chance of exploding and causing untold amounts of damage to the home, and people, around it.

Moreover, regularly checking the pressure in a heating unit can expose problems that possibly were not noticed before. Over time, a machine will experience wearing. To the untrained homeowner, this goes unnoticed. Eventually, cracks do develop, and this means that unwanted and now wasted gas is leaking into the home. A regular check up on the gas pressure can detect these problems, and put an end to them before they become much worse.

While quite a few homeowners will have the do-it-yourself attitude, it is highly recommended to instead have a trained technician come in a thoroughly check the machine. While the associated upfront cost may be higher, the risk of having damage to home and family is significantly reduced.

Why is my boiler acting up?

3 Signs Your Boiler Needs To Be Repaired


London Boiler RepairProper home management is always a key thing when it comes time for someone to own a home. However, being able to maintain the home is just as important because sometimes appliances start to break down. Boilers are one such example of appliances that may need repair.

A good sign that boiler may need repair is when the boiler starts to make a wide variety of sounds not normally associated with it. For instance, there may be a loud banging or a high pitched whining noise coming from it, which would indicate a loose belt inside. If there are any strange noises coming from the boiler, then the need for repairs should be immediate.

Another sign that boiler repair may be necessary is when the heat output around the house isn’t as high as it normally would be. Simply adjusting the thermostat would be enough to disperse heat around the home but there may be times when that isn’t going to fix the problem. The problem could be linked to a faulty thermostat or also to any potential leaks that may be in the boiler itself. This can be just as bad during the winter if ice is forming in places where it shouldn’t, since the heat is dispersing outwards instead of staying around in the house where it normally would.

The pilot light coming on is another sign that the boiler may need to get some repairs. The purpose of a pilot light is to determine the gas quality in the boiler, and if it starts to burn yellow then that indicates that there is a serious problem with the quality and combination of gas in there, particularly carbon monoxide. Needless to say, making repairs for this should be done as urgently as possible. It is very important to take note of this, as it could lead to serious health problems for the occupants of the home, in addition to asthma and allergies.

In conclusion, there are many signs that show that a boiler may need repair. Between warning lights and low heat flow, getting the repairs is vital.

What’s wrong with my boiler?

3 Signs Your Boiler Needs a Tune Up


London Heating EngineerA boiler is an excellent source of heat for your home. Annual preventative maintenance for your boiler is recommended to keep it running as efficiently as possible and avoid a dreaded mid-winter breakdown. Sometimes though your unit may require a tune up before your planned maintenance inspection. There are three helpful signs to keep in mind indicating that a tune up is in order.

Banging Noises: Boilers are complex, mechanical units so they do tend to make some noise, they should overall be fairly quiet and go unnoticed, but you should be fairly familiar with the normal sounds that your unit makes as it works. Pay attention to any odd noises, particularly banging sounds when you turn your boiler on. This can indicate a problem with your blower motor – it will usually need to be adjusted or repaired in some way. Occasionally, banging noises can be an ignition delay, which is actually dangerous.

Utility Bill Increases: A sudden spike in your utility bill with no other known cause can sometimes reveal a boiler issue. It is expected that your energy bill will increase during the winter months, but unless there has been a rate change, your bill should be roughly the same each month. When various parts of your boiler malfunction, need to be replaced or repaired, it can cause your boiler to have to work a great deal harder to get the same job done. Even a small, quick-fix sort of repair that a tune-up can handle will take a toll on your unit’s efficiency. This will in turn show up on your utility bill.

No Heat: Not having heat is probably the most obvious sign that something has gone wrong with your boiler. There are many different reasons that cause a boiler to unexpectedly stop working. Along with a routine maintenance plan it is a good idea to test your boiler before it gets particularly cold out. Make sure it is producing heat and enough of it. Again, boilers are complicated and have many mechanical parts. Sometimes a small thing can go wrong and affect the whole system. Any heating issues definitely call for a tune up.

Where can I find the right HVAC engineer for me?

How To Make Sure You’re Hiring The Right HVAC Engineer


London HVAC Your home is one of your biggest investments, so you’re going to want to make sure it stays properly maintained which will extend the longevity of your home and everything inside it. Having efficiently working appliances is just one of the responsibilities that comes from owning your own home, or even if you’re just renting. One of the most important factors is making sure you choose the right HVAC heating engineer, doing so can ensure that any HVAC work you may need gets properly handled the first time and reduces the risk of needing more work (or having to have the work redone) in the future; which will only cost more.

When it comes to hiring an HVAC heating engineer, you’re definitely going to want to make sure they’re licensed. Letting anyone, or even yourself, do any kind of work on or in your home without having the proper license with the knowledge of doing so is a costly risk. You can ask a engineer how long they’ve been in the business to see how much experience they have; a more experienced engineer is going to know how to handle your HVAC problems effectively and efficiently. It’s also a good idea to make sure that the engineer (or HVAC company you hired them from) you hire has proof of liability and worker’s compensation insurance; because otherwise, if they don’t, you’ll be held liable if anything happens on your property. Checking to see if your engineer complies with safety and health laws is also recommended to ensuring that you pick the right engineer.

Getting a consultation with a HVAC heating engineer before getting the work done can ensure you that you’re hiring the right one. You’ll be able to ask questions and have any concerns addressed. They’ll also be able to go into detail about how they’ll go about fixing your HVAC problems to get the job done.
