Heating Tune Up and Furnace


A heating service we offer our customers is known as furnace tune-ups, important for maintaining maximum efficiency and output. 

A heating or furnace tune-up is different from a heating repair in that it helps maintain your furnace for improved reliability and durability. 

What is the goal of a Heating Tune-Up?

The goal of a heating tune-up is to keep your system in like-new condition, which helps prevent breakdowns, extend the life of the furnace, provide healthier indoor air and use less energy to save you money on your utility bills.

Other Things We Look For During Heating Maintenance Tune Ups

Maintenance Tune ups are so important for your furnace because it ensures a long longevity for your system.

Much like taking your car to the shop every few months, we perform system checks on your furnace to keep it running smooth all year long.

Not having regular tune-ups can lead to costly repairs down the road or even a hefty replacement.

In addition to the checklist above, here are some other things we check for during a routine heating tune-up service:

Dirty Air Filters
. For maximum HVAC performance and airflow, air filters should be replaced regularly. Assured Comfort recommends changing the filters every 3 months.

A dirty air filter can cause your HVAC system to use more energy when pulling air through the filter, which results in higher energy bills, poor overall HVAC performance, and dirty indoor air. An extremely dirty filter can cause your entire system to eventually freeze and shut down.

Clogged Drain Lines. This is a result of the build-up of dirt and other organic materials in your home’s drain lines. Clogged drain lines can lead to severe HVAC damage because they cause water to back up and ultimately overflow the drain pan. In addition, clogged drain lines can result in mold and mildew growth, which left untreated, can be dangerous to your health.

Blown Fuses. Sometimes a blown fuse is a result of a breaker issue. However, fuses that blow frequently could indicate more severe problems with your HVAC.

Refrigerant Leaks. An HVAC system should not leak refrigerant. If you’re experiencing refrigerant leaks, this is a problem that requires repairing rather than simply replacing the refrigerant. 

If you’re noticing higher utility bills or longer than usual times for your home to reach your desired indoor temperature, your refrigerant levels may be too low. In either case, please call Assured Comfort so we can inspect your refrigerant levels.

This is something we always check out during routine maintenance. Keep in mind Refrigerant R22 is in the phase-out process because it’s harmful to the environment as well as indoor air.

Refrigerant leaks are not normal and according to the EPA are bad for the environment. Refrigerant levels are always checked during routine maintenance. We can check to see if your system currently uses R-22, which we can replace. Handling freon can be dangerous, and should only be performed by a professional HVAC technician.

Dirty Condenser Coils. Failure to have your condenser coils cleaned can negatively impact your HVAC system’s performance. In fact, dirty coils can reduce your system’s efficiency by nearly 40%, which can shorten the lifespan of your unit.

Electrical Problems. Wiring and electrical components of your HVAC should be checked regularly by an HVAC technician to prevent system malfunction and even entire system outages.

Frozen Evaporator Coil. Low refrigerant levels can cause the evaporator coil to freeze, which can result in restricted airflow. An HVAC technician will inspect your evaporator coil during a routine maintenance to make sure it isn’t frozen or in a position to freeze over.

Thermostat. Thermostats are used to control the temperature of your indoor air. Sometimes, they can break or stop working and require a replacement. Contact your HVAC technician if you think your thermostat needs an upgrade. Did you know that keeping a consistent temperature in your home can also keep a furnace running smoothly during winter?

Shutting the system off and on is worse than keeping your thermostat at the “heat” setting during winter and leaving it at the optimal temperatures when you’re away and when you return to your home, which is generally somewhere between 68 and 72 degrees Fahrenheit. That’s during the waking hours of the day when family members are home.

The thermostat can be turned to between 62 and 58 degrees (or even a little lower) when household members are away at work or school, or at night when everyone is sleeping underneath their blankets in bed.

There’s no need for your furnace and heating system to waste energy since when family members are asleep and less active. This temperature range is also just high enough to prevent pipes in the home from freezing if outside temperatures dip and family members aren’t home to address the situation.

It’s also a good idea to resist turning your heat off completely when you’re not home.

Turning the heat off entirely means your house is largely subject to environmental factors.

So if it’s super chilly outside and there’s an arctic blast blowing, your house will cool down so much while the heat’s off, that when you get home and turn the heat back on to bring your house back to a comfortable temperature, you will cause your unit to work harder, use excessive amounts of energy and cost you more money than if you only turned your thermostat down 10 degrees or so while you were away.

Certainly having a programmable or smart thermostat makes this kind of regular temperature adjustments much easier to maintain.

A programmable thermostat can regulate household temperature according to your activity, sleep and work schedule. You can program your thermostat to change the temperature about half an hour before you wake up in the morning, leave for work, arrive home from work, and go to sleep at night.

You can also have a separate temperature programming for the weekends while you are home more. According to heating industry experts, a programmable thermostat can reduce your heating bill by 10 percent by automatically making adjustments in your home’s temperature during the day.

It’s worth noting that the temperature ranges we’ve stated here are just guidelines.

Probably most people will fall within 68 to 72-degree daytime comfort range, but not everyone will find the exact same temperature ideal.

Exactly where you and your family members fall within these ranges is subjective.

Chances are, there’s going to be someone in your household who’s comfortable with temperatures a couple degrees cooler or warmer than others in the family.

The challenge is finding that happy medium.

If everyone in the family likes the thermostat set to 70 and you’re the only one who’s still chilled, you may just need to invest in some extra slippers and sweaters so that you can keep the rest of the family happy.
