My furnace went out and I had several companies bid for the replacement and all were comparable in price. I went with Allegiance Heating & Air, LLC because they seemed the most knowledgeable and I felt comfortable with them in my home. They replaced it the very next day and were great! Great experience!

HVAC Repair in Pekin, IN And Surrounding Areas

Your HVAC system uses more energy than any other appliance in your home. It also affects how the other appliances function and is one of your home’s greatest assets.

It keeps you comfortable through the sweltering Summers and icy Winters of Pekin, IN. When it’s not working properly, it can create a major disruption to your home and family. In times like these, it helps to have a reliable HVAC repair company you can count on.

Signs You Need an HVAC Repair

It’s easy to recognize when your HVAC system is not working to its full potential. Suddenly (or sometimes over time) your normally comfortable house in Pekin, IN And Surrounding Areas, becomes either too hot, cold, or muggy and stuffy. But knowing what’s wrong and how to fix it is another story.

There are two sides to your HVAC system – the furnace and the air conditioning side. When your system isn’t working as it should pay attention to these simple signs that may help you see what side of your system needs an HVAC repair; and what you can do to fix the problem quickly.

Signs Your Air Conditioner Needs Repair

  • Feel the air in the vents: If the air coming out of your vents is hot– this is a problem with the A/C side. Hot air may be due to a compressor or refrigerant issue. This is actual news. Both of these issues are fairly simple HVAC repairs and inexpensive to fix.
  • Look for moisture around the system. Look in your utility closet for moisture anywhere around the air conditioning system. If you see any type of standing water or leak, it needs to be addressed quickly to get your A/C repaired and avoid further problems.
  • Listen for uncommon sounds. Your HVAC unit should run relatively quietly. If you hear any type of uncommon sounds like grinding, squealing, or banging, that’s a problem. This is a good time to call a Pekin, IN, HVAC repair technician to see what is happening on the inside of your system that is causing the problem.
  • Smell Unusual smells. Take a good whiff and see if you detect any hint of mold, burning, or gas. Natural gas is an immediate furnace issue, but mold or burning may be an A/C problem. Oftentimes, odd smells can be a sign of burned wires inside the unit or a moldy smell may be an issue with the AC not circulating air properly.
  • Feel your home for excess humidity. If you walk inside during a Pekin, IN, Summer and you still feel the humidity, it’s a good indicator that your air conditioner needs to be looked at. Your air conditioner should act as a dehumidifier in your home, sticky air is sometimes one of the first signs that something isn’t right.

Signs Your Furnace Needs Repair

  • The smell of gas or other fuel typically indicates a furnace problem that should be addressed quickly.
  • If your unit has trouble starting or stops frequently before reaching the desired temperature, this may be a furnace issue.
  • CO2 detectors going off are connected to a problem within your furnace.
  • A discolored pilot light that is anything other than blue is an issue to call a furnace technician about immediately.
  • If you do not have adequate heat or a comfortable temperature during the Winter months in Pekin, IN And Surrounding Areas, this is a sign you may need a furnace HVAC repair or maintenance.
  • Squeaking or whistling from your furnace is not normal and should be checked out by an HVAC technician.

How to Tell if You Need to Replace Your HVAC System

    1. Safety First:The health and safety of your family is our number one concern. Don’t risk carbon monoxide poisoning or other dangers to save money on a furnace, there are financing options available to help keep you and your family safe.
    2. How old is your system?The average lifespan of an A/C unit in Pekin, IN And Surrounding Areas, is about 10-15 years, furnaces tend to last a little bit longer. The lifespan of your system is directly related to the maintenance and care it is given. If you’re over 10 years, for either system it might not be worth the cost to repair it.
    3. Does your A/C use Freon:The R-22 Freon has been phased out for more efficient options. The new “Freon” is an R410A refrigerant. If you’re using R-22 in Pekin, IN And Surrounding Areas, you need to replace your unit.
    4. Constant HVAC repairs:Have you had more than one minor HVAC repair in the last year? If so, it might be time to replace your unit. Chances are, small HVAC repairs will add up over time and you’ll be better off replacing it sooner than later.
    5. HVAC repair Costs:There is a simple equation, you can use to determine if it’s more economical to complete any HVAC repair or full system replacement. Take the estimated cost of HVAC repair and multiply it by the age of your unit. If that is more than the cost of a new unit, it’s time to replace it.

For example: If you have a $50 repair on a 5-year-old HVAC (50×5=250). That is a valid repair. If you have a $200 repair on a 10-year-old unit (200×10=2000) It might be worth looking into the cost of a new system.

  1. Cost of energy bills:A typical HVAC system accounts for 50% of the utility bills for homes in Pekin, IN And Surrounding Areas, each month. If your energy bill keeps going up, but your rates remain the same, your unit is having to work harder and consume more energy to keep up. There’s no way to fix this, and it’s time for a replacement soon.
  2. Efficiency of your current system:If your current system has a SEER rating of below 13, or if it’s the wrong size for your home, it’s probably time to replace it.

How Long Will Your HVAC System Last

Your HVAC system is one of the biggest assets to your home or business. So it only stands to reason that you would want it to last as long as it can. The short answer is: it depends on how well you maintain it. Maintaining your HVAC system could get you an additional 10 years before you have to worry about a replacement. With regular HVAC maintenance and HVAC repair, your system should last a good 15 to 25 years.Some of the features on your system may need to be replaced before the full unit goes out. For example, the dehumidifier usually lasts 8-10 years and sometimes the ventilation or ductwork may need additional maintenance.

HVAC maintenance

The lifetime of the system also varies based on the type of system you have. Oil-based furnaces will only last a few years, while geothermal systems may last you your entire lifetime. Both of these systems are rare in Pekin, IN And Surrounding Areas. Boilers are an outdated system in most areas that tend to last a little bit longer than central air systems, but not by much.

Benefits of a Well-Functioning HVAC System

Fifty years ago, having a cooling and heating system for your home or office in Pekin, IN And Surrounding Areas, was seen as a luxury. Today, it is a necessity. Not only have we grown accustomed to this comfort, but the benefits of a well-functioning HVAC system are essential to the proper day-to-day function in today’s world.

  • Furnace and A/C savings: When you replace an older system, you will see the benefits on your energy bills right away. Older systems use more energy and therefore cost more to run daily.
  • Comfort: Increased technology makes your home more comfortable than ever. Consistent levels of airflow maintained humidity controls and constant temperature monitoring are just a few of the features that make your HVAC system essential.
  • Air Flow: Better air flow means more comfortable temperatures throughout your house and less static air that becomes stagnant and moldy.
  • Noise: Older models are significantly louder than the latest model of HVAC systems on the market. Today’s equipment has sound-absorbing technology to ensure you stay comfortable without the additional noise of traditional HVAC fans and motors.
  • Environmental Impact: A well-functioning HVAC system conserves more natural resources by using up to one-third less fuel than older models.
  • Options: Now, your HVAC can learn your habits and your work schedule to keep your home comfortable while you’re home and save money while you’re gone.
  • Increased Resale Value: A new high-efficiency HVAC system can give your home the leading edge and is quite appealing to home buyers in Pekin, IN And Surrounding Areas.

Benefits of Proper HVAC Maintenance

Some home and business owners have the notion once you install an HVAC system you can shut the door and forget about it for 10 years. This could not be more wrong. Just as your car requires oil changes and your teeth require a cleaning, proper maintenance is important, and your HVAC system is no different. Regularly scheduled HVAC maintenance has a whole list of benefits including:

  • It will save you money by preventing costly breakdowns and lowering your energy bills. A well-maintained system also lasts longer and stays under warranty so you don’t have to worry about unexpected and expensive HVAC repair bills.
  • Avoid unnecessary HVAC repairs by checking on your system regularly. Most large repairs start as small issues. When these are caught early on, you avoid big breakdowns later.
  • Keeps your home safe from CO2 and refrigerant issues. Both of these ingredients can be potentially harmful and even fatal. Having expert technicians in Pekin, IN And Surrounding Areas, to maintain your system ensures your home and family are safe.
  • Extends your unit’s lifespan by up to 10 years with regular maintenance so you can enjoy your system for longer and keep it working perfectly for years to come.
  • Higher energy efficiency means your system will work better while using less energy. This will show up on your utility bills each month and will keep your family more comfortable without costing you.
  • Better indoor air quality is possible with a well-maintained HVAC system. The EPA estimates indoor pollutants to be 2-5 times higher than outdoor pollution. HVAC maintenance helps to keep the air in your home or office clean and filtered.

FAQ’s About Heating & Cooling

They are sized according to their tonnage. Residential systems can range from 1 to 5 tons. If your system is too small, it won’t heat or cool adequately. If it’s too large – you overpay each month on your utility bills by running a huge system, you don’t need.

This very much depends on the weather in Pekin, IN And Surrounding Areas. However, the average air conditioner is sized to remove the heat from your home as fast as it comes in.

You can control this based on your thermostat settings. Your A/C system should be able to cool the air to about 20 degrees below the outside temperature with no problems. If it’s not cooling adequately, it might be time for an HVAC repair.

This is a matter of personal preference, but we recommend keeping your thermostat as hot as you can stand in the Summer and as cool as possible in the Winter. For most customers, this is between 78°-80° in the Summer and 70°-72° in the Winter.
