Most Common HVAC Problems

Your HVAC unit plays an important role in the overall comfort of your home. It can be easy to forget just how important it’s job is until something seems broken and the temperature is sweltering hot or bitter cold. If you are experiencing issues with your HVAC unit, you might be able to troubleshoot them yourself, or in some cases you may need a licensed expert from A. J. Danboise to come take a look.

Here are some of the most common HVAC problems, and suggestions on how you or your local HVAC expert might be able to solve them.

1.      Dirty Filters

Even if you have the best HVAC unit on the market, it will not operate at maximum efficiency with a dirty filter. Filters should be changed at least once every 90 days, or sometimes even as regularly as once per month. If your filter becomes too caked with dust and pollutants, your HVAC will have to work harder to maintain the air flow and cool your home. This issue has the easiest fix on the list: just make sure to check on your filter and replace it as it gets dirty.

2.      Refrigerant Leaks

Most HVAC units use a liquid refrigerant to cool air as it flows into your home. However, if this substance finds an escape route and leaks out of your unit, there will not be enough to chill the air adequately. Warmer air blowing into your home can be a inconvenient or even extremely uncomfortable depending on the season. If your refrigerant levels seem low, call an HVAC technician to have them assess the problem. They can compare the levels your unit is using and compare them to the manufacturer’s specifications for that HVAC.

3.      Thermostat Sensor Issues

The sensor inside your thermostat is used to detect the air temperature inside your home. Based on the temperature it reads, it will signal your HVAC to turn on or off. This process is designed to ensure your HVAC maintains a comfortable temperature in your home. If your air conditioner or heater does not seem to turn on when it needs to, or it turns your HVAC on and off too many times per day, your sensor might not be operating properly. A licensed HVAC professional can help you determine if the problem is with your thermostat rather than your unit.

4.      Ignition Problems

Sometimes elements like pilot lights, igniters, or other electrical components within your HVAC are due for a replacement. If your HVAC has issues starting, you might be able to take a look inside and diagnose the problem yourself. However, it is best to have a professional do any replacements within your unit.

5.      Uneven Heating or Cooling

If some parts of your home are receiving more cool air in the summer or warm air in the winter than others, the problem might not be with your HVAC. Sometimes if certain rooms don’t seem to have climate consistent with the rest of the house, it has to do with gaps in their sealing. If you can seal up these problem areas, it might improve the air flow and temperature control.

Fall has officially arrived in Southern Michigan, bringing with it a welcome lull in temperatures. With cooler days and even colder nights, your air conditioner is finally able to get a break from the hot summer months, but don’t send your HVAC system into hibernation yet. The subtle decrease in temperatures is the perfect time of year to prepare your HVAC system for the heating season. These 8 easy steps will ensure your HVAC system is ready to deliver when the winter months arrive.

Step 1: Check and replace your air filters.

Regularly checking and replacing HVAC filters is one of the most important things you can do to ensure the systems longevity and prevent breakdowns. Change air filters at least every 3 months. For allergy sufferers or homes with pets, change filters more frequently.

Check your air filters every 2 to 3 weeks to make sure they are functioning properly. Improperly functioning air filters can prevent a home from heating or cooling adequately and efficiently, taxing your system and increasing costs.

Step 2: Clean your outdoor unit.

This fall, check your outdoor unit for debris and damage. Trim any tall grass, shrubs, or trees that have grown too close to the exterior unit before winter weather arrives. Then, clean the unit by switching it off and rinsing out dirt, twigs, and any other debris with a garden hose.

This is also a good time to notice if there is any damage or debris that is hard to remove from your outdoor unit. For damage or anything unusual, call AJ Danboise and speak to one of our HVAC professionals.

Step 3: Clean your air ducts and vents.

Air ducts and vents are responsible for circulating air throughout your house. To make sure the air in your home is being properly filtered and circulated, regularly clean your air ducts and vents and have all of the registers open. Obstructed air ducts force HVAC systems to work harder, decreasing both efficiency and lifespan.

To get your air ducts and vents ready for fall, check to make sure all of the registers are open and that they are not covered or obstructed by furniture, drapery, or other items. Then, vacuum any visible dust from your air ducts and vents. Use a wet cloth to remove any dust left behind by the vacuum.

Step 4: Find and seal any possible air leaks.

Air leaks are the number one cause of inefficiency in HVAC systems. Check windows and doors for any air that might be coming through. Apply weather stripping to windows and doors to seal them from air leaks. If you consistently feel some rooms are warmer or cooler than others, the air leak may be coming from your ventilation ducts. One of our HVAC professionals at AJ Danboise can help you identify the leak and prepare your home for the heating season.

Step 5: Examine furnace burners and blowers.

Fall is the perfect time to test the furnace to make sure it is working properly before relying on it in the winter months. Before turning your furnace, check for any dust or obstruction that may have accumulated over the warm summer months.

Then test the furnace and burners to make sure they are working properly. If you notice anything unusual, call AJ Danboise for a furnace inspection to make sure your HVAC system is ready to heat before the colder months are here.

Step 6: Program your thermostat.

Weather patterns change frequently in the fall in Southern Michigan causing a range of temperatures. This is a great time to invest in a programmable thermostat, if you have not already. Programmable thermostats change based on the outside temperature, helping your HVAC system work more efficiently. With the constant fluctuation in temperatures as seasons change, a programmable thermostat extends your system’s life and saves money on heating and cooling bills.

Step 7: Schedule a professional HVAC maintenance.

Before the colder winter months set in ensure your HVAC unit is functioning properly with a professional HVAC maintenance. Regular maintenance will make sure your system is functioning properly and efficiently when you need it the most.

Step 8: Test it out.

The final step to getting your HVAC ready for fall in Southern Michigan is to test it out. Once the equipment has been cleaned, inspected, and the settings have been adjusted, test the system to make sure that it is working properly.

Don’t get caught in the cold this winter! Use these steps to make sure your HVAC system is ready to function properly and efficiently before you need it most this winter. If you notice anything unusual, we, at AJ Danboise can help! Call today at 1-248-236-5999 for all your fall preparation needs!

Fall Maintenance Checklist for Your Home

With summer becoming a faint memory as the weather begins to cool off, it’s time to get your home ready for the upcoming fall season with a few simple chores around the house! The experts at AJ Danboise have put together some essential tips for preparing for the autumn chill.

Clean Your Gutters
Have all your leaves fallen and left your trees bare? If that is the case, it is time to head out and get those gutters cleaned before the winter season hits! Clogged gutters can cause water and ice to gather which can cause potential damage to your roof or to the siding of your home. Avoid the what ifs and get them cleaned out!

Rake It Up
With all those extra leaves cluttering your lawns, it is about time you bust out that handy-dandy rake and get them cleaned up. By leaving these leaves on the ground during the winter season, you can inhibit spring growth for your lawn.

Seal Up Open Gaps
During the winter, many outdoor critters are looking for a warm place to take shelter from the cold. Avoid those pesky critters from making your home theirs by sealing up any open gaps. If it looks like a place they can enter - it is probably best for you to just seal it up.

Store Garden Hoses
During the winter, don’t forget to remove your garden hoses and make sure they are properly stored away. You shouldn’t leave them on because water can freeze and expand causing the pipes or faucet to break - which would result in a major plumbing disaster. Lastly, you should also turn off the shut off valves to prevent a potential expensive lawn sprinkler system repair. Consider this step a preventative investment for not only your pockets, but also your lawn!  

Give Your Furnace a Check
Getting your furnace checked and tuned up should be at the top of your agenda for the winter season. Your furnace is the headquarters for keeping your family warm throughout the wintry weather months, so it is important to get maintenance performed on it while the weather is warmer outside. A fully functioning furnace will ensure maximum heat output all winter long. Another benefit is that your furnace will be running at its best and most efficient levels. This can help save on your utility bills each month.

Your fireplace is often neglected during the warmer months, so you may forget to give it a once over before firing it up this winter. Check your chimney for any buildup so that you can get it cleaned out. If you see any obstructions, make sure to remove those as well. Any cracks in your brick or mortar, should also be fixed beforehand.  

Be sure to schedule an appointment for one of our professional technicians to come out and inspect your HVAC system. We can check your furnace and heating to make sure you are prepared for the fall and winter months. Our experts will also check your fireplace and make sure it is cleaned out and ready for the colder season. Call AJ Danboise at 248-236-5999 and give your HVAC unit some TLC before the winter leaves you in a tough situation!

Summer HVAC Maintenance Tips

A typical household spends roughly $2,200 a year on energy bills, and nearly half of that comes from heating and cooling costs. With the summer heat in full force, people here in Michigan are turning their air conditioning up to full blast. But you can save electricity and avoid hefty repair bills by giving your HVAC system an annual check-up. In fact, the best time for summer HVAC maintenance is right before extreme temperatures hit, so try our energy-saving tune-up tips today!

DIY Maintenance

Clean & Change the Air Filter. If you only make one tune-up this season, make sure to give your air filter some TLC. Cleaning your air filter can lower your air conditioner’s energy consumption by up to 15%. In the summertime, you should wash your reusable filter or replace your disposable one at least once per month.

Clean the Area Around Your Outdoor Unit. Keep vegetation at least two feet away from the unit so it is free to pull in air. This includes making sure your grass is not too tall and raking up leaves in the fall season.

Call a Professional

Some parts of a thorough annual check-up require taking apart an AC unit, so you’ll need to call a service technician for a quick, professional check-up. If you call one of our technicians to service your HVAC unit, we will do the following:

Clear the Drain. A clogged drain can waste nearly as much energy as a dirty filter because your unit has to work harder to send out even less cool air.

Clean the Outdoor and Indoor Units. The technician will keep the outdoor condenser fan running efficiently by cleaning the fan blades and will maintain the unit’s ability to cool the air moving through it by removing dust and other buildup from the indoor evaporator coil.

Help Your HVAC Save Energy

To get the most bang from your HVAC buck, use these general energy-saving tips. They will help you support your system and save energy around the house.

Get a Programmable Thermostat. It’s easier to save energy with a programmable thermostat than a regular one because you don't have to think about it each time you want to change the temperature. You pre-program your settings so that the thermostat raises the temperature while you're at work and asleep, and kicks on the air conditioning when you're at home and awake. With "smart” programmable thermostats, you can even control the temperature from your smartphone.

Seal Your Heating & Cooling Ducts and Any Open Spaces. Make sure doors, windows, and nooks and crannies are shut and properly sealed. The less cool air that escapes your home, the less energy you'll waste, and more comfortable you'll be.

Set Your Thermostat to Your Ideal Temperature.  Setting the air conditioner to a colder-than-desired temperature doesn't cool down your house any quicker – it just keeps the unit working longer than necessary. So, set it to where you want it. And remember: You save up to 1% on your yearly cooling bill every time you raise the temperature by one degree for a period of eight hours. So, set it to around 78° - after all, it is summer!

Using a humidifier in the summer seems a bit ridiculous. After all, why would you want to be humid during the hottest season? Summer doesn’t always mean it’s time for fun activities and hitting the pool. Summer is the prime season for allergies. With all the bugs and pollen spreading throughout the air, it’s not uncommon to notice more runny noses than usual. On top of that, the constant use of an air conditioner can make the air dry. Dry air can cause irritation if allergy symptoms are already present, and can even lead to infection in some cases.  


What role would a whole house humidifier play in fixing any of this? The uses of a humidifier go beyond just making areas in your home humid. In fact, there are some significant reasons to use a whole house humidifier in the summer, and the experts at AJ Danboise have documented them for the benefit of our Southeastern Michigan neighbors.


Benefits for Summer Humidifying:

It Can Remedy Allergies

  • Hydrating during allergy season is helpful in fighting the symptoms.
  • Having cool mist absorbed by your body will help energize it and clear up congestion in the nose and throat.
  • Humidifiers can help fight off infection with their ability to kill germs and other contaminants.
  • Combatting dry air can build your body’s defense toward sicknesses and allergies.


It’s Healthy for Your Skin

  • Whether or not you’re sick, your body needs moisture.
  • Using a humidifier to moisturize is great for your skin, and can help clean your pores as well.
  • Hydrating your skin will give it a healthier look and keep your body temperature at a stable level.
  • The hot sun can dry out your skin, so it’s good to rehydrate constantly.
  • Keeping your skin hydrated will help prevent wrinkles as well.


It Can Cool You Down

  • Fighting the heat can be difficult during the summer, but a humidifier can help cool you down without using a lot of energy.
  • Using a humidifier in tandem with the air conditioning can keep rooms cooler, allowing you to raise the temperature of the A/C – and use less energy.
  • Using a humidifier can make you feel cooler for longer periods of time, due to the hydrating nature of the affected air.


A humidifier can make your summer even better. If you notice any damage or leaks in your humidifier, contact AJ Danboise today. We specialize in whole house humidifier installation and repair, and are always looking out for our Southeastern Michigan neighbors. Give us a call at 248-236-5999 to schedule an appointment and get started. Remember to stay hydrated and have fun this summer!
