Common Causes of Uneven Temperatures in the Home

Schedule Now

Temperatures in your home can vary from room to room, from level to level and even from one spot in a room to another. The causes of uneven temperatures are many, and solutions can vary, from regular air conditioner and furnace maintenance, to installing the right size HVAC system for your home. The following remedies may cure cold or hot spots in your home.

Do-It -Yourself Solutions

Correct uneven temperatures with simple solutions such as these:

Change air filter. Dirty air filters slow down airflow so that conditioned air can’t reach rooms in the volume needed to cool or heat. Check your filter and change it regularly.

Unblock registers. Have you placed furniture or other obstructions in front of or on top of air registers? Try moving the obstructions and see if the situation improves.

Check return vents. Check return vents for dirt and dust buildup. Use the brush attachment on the vacuum to clean the vents.

Reverse ceiling fan blades. If your ceiling fan blades can be reversed, switch them to go in a clockwise direction in the winter. This pushes warm air from the furnace down to floor level.

Adjust dampers. If your system has dampers, try adjusting them to provide the right amount of conditioned air in each room or level of the house. Do not close them completely.

Professional Solutions

Correct HVAC sizing. Unfortunately, HVAC systems are often sized incorrectly, resulting in uneven heating and cooling of the home. The best time to correct this is when you are looking to replace the furnace or A/C. Have your consultant accurately gauge the correct heating and cooling load, what size equipment is needed, and how much ductwork capacity is needed by using industry software called Manuals J, S and D.

Inspect ductwork. When you schedule A/C or furnace maintenance, have your ductwork inspected for holes and loose segments. You may even repair them yourself with mastic sealant and foil tape.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
