Getting Your Furnace Ready for Winter

So far, we’ve been pretty lucky as far as temperatures go this year, but the fact remains that, sooner or later, those temperatures are going to plummet. If you haven’t already prepped your furnace for the upcoming winter months, now is the time to do it. In this part of the country, having a good heating system is crucial, and the last thing anyone wants is to be stuck with a broken furnace when winter’s chill really sets in. Avoid panic by making sure your furnace is in good working order before disaster strikes.

Preparing You Furnace for Winter

Clean Up

If you’ve stored anything near your furnace while it hasn’t been in use, remove it. Also, make sure there isn’t anything on top of or in front of your air ducts or return vents as obstructions could prevent proper air flow and efficient heating.

Replace your furnace filter, and clean dust and debris from vents and burners.

If you have a chimney, inspect it, and remove any debris or bird nests. If it hasn’t been professionally inspected recently, consider calling in an expert to ensure that it is in good condition.

Test Your Thermostat

A thermostat that isn’t working properly can cause major headaches. To test it, simply turn it on and see how it responds. If you have an older thermostat, consider replacing it, even if it’s working fine. Modern thermostats are more efficient. If you opt for a programmable thermostat, you can set it to automatically lower the temperature when you’re away or sleeping, saving you a considerable amount on your heating bills.

Troubleshoot Air Conditioning Problems

The last thing you want to happen on a hot summer day is for your air conditioning to stop working properly. We’ve all been there a time or two. It’s as if your air conditioner is fighting against you, purposely malfunctioning on the hottest day yet, just to get a good laugh. Learn how to troubleshoot air conditioning problems before they become problems!

DIY troubleshooting air conditioning

We’ve put together a list of several of the most common air conditioning problems and how to troubleshoot them. Some of these should by default be left to a certified technician, and we’ll be sure to let you know which ones.

Should you experience any trouble while attempting to troubleshoot air conditioning problems or don’t feel comfortable working on your unit altogether, leave the work to a licensed, trained HVAC professional as you wouldn’t want to cause any further damage to your system.

How to Troubleshoot Air Conditioning Problems

1. Faulty Installation/Improper Sizing

Proper sizing and a precise installation is of the utmost importance when it comes to installing an HVAC unit. A possible indication that your unit wasn’t installed correctly is if it short cycles or if your home never feels cool enough.

If this is the case, have an expert inspect the entire system and ensure that your unit is cooling efficiently. The size of your unit is dependent on the square footage of your home that needs cooling. To give you a better indication, Energy Star has put together a A/C Sizing Chart:

2. Low on Refrigerant

If your unit is low on refrigerant, it means that it was improperly charged or you have a leak. In both cases, it’s imperative that you call a technician as soon as possible to inspect the issue, making any necessary repairs and/or charging the system correctly.

It is not as simple as adding more Freon; if your have a leak, you need to schedule air conditioner repair immediately. Beware of HVAC companies that only refill your refrigerant without addressing the underlying leak problem.

3. Inadequate Maintenance

How well your HVAC unit functions is entirely dependent on how often you schedule professional maintenance. You wouldn’t neglect your car for years on end, so why neglect your HVAC unit? Much like your car, your HVAC unit has numerous parts and components that need cleaning and adjusting annually so that it can operate at maximum efficiency.

Life is often fast paced, with work and/or classes, having to take care of the kids and keep the house clean, prepare dinner, etc. It seems like sometimes there isn’t a moment to spare. Scheduling a tune-up for your unit is the last thing on your mind right now.

The easiest solution is to join a maintenance program; that way, it isn’t your job to remember to schedule your appointment! They’ll do it for you at your easiest convenience.

4. Poor Airflow

If your home isn’t as cool as you’d like to be, there are a few things you can do before calling in an expert. Put it on your chore list to vacuum vents regularly as this will cleanse your vents of all the dirt and debris that could be blocking airflow. Clear away anything that could be blocking airflow, such as furniture, rugs, drapes, etc.

If you really want to improve indoor air quality and home energy efficiency, your best bet is to have your air ducts professionally cleaned every 5-7 years.

5. Change Your Air Filter

One of the most important things you can do to ensure proper airflow is by changing the air filters regularly. While our technicians can change your air filter when performing maintenance, that’s just twice a year.

On average, you should change your filters every 1-3 months to ensure a healthy flow. Forgoing changing the air filter will lead to poor indoor air quality, uneven heating and cooling, short cycling, strain on your system, and a buildup of dust and dirt on your HVAC fan blades and around vents. Put reminders in your phone and calendar so you never forget.

We recommend using HEPA (high-efficiency particulate arrestance) filters. Although they cost more, they do a better job of filtering your indoor air and last a lot longer,
