Furnace or AC Unit? Common Types of HVAC Systems

After 30 years in the HVAC business, we have learned how to help customers with any type of home ventilation system. From interactions with our cherished customers over the years, it appears that homeowners know a fair amount about home heating and air conditioning options. It’s great to have in-depth conversations about some of the key features of the homes air control system.

One question we keep getting asked is: what are some of the common types of HVAC systems that could work for me? This post is meant to answer this question for all our inquisitive customers.

Single or Multi-Stage System

Single and multi-stage systems are popular in hot and cold climates alike. The system is designed to operate effectively on the hottest or coldest days of the year, thus guaranteeing warmth or cool air throughout the home.

Single-stage systems are common in older homes and can only operate at only one level of heating or cooling. This can get expensive and be rather loud to live with, which is why the multi-stage system was designed. The multi-stage system operates much like a light dimmer switch in that it has the ability to adapt to the temperature outside.

The single-stage system is certainly less energy efficient than the multi-stage system. It’s a popular choice for homeowners with older property to update their HVAC system to multi-stage.

Zonal System

Another newer option is a zoned system. The home’s furnace or AC unit can be applied only to specific areas of the home that need it most. It is the most effective way to deal with heating and cooling in the home, and most homes built today come with this kind of infrastructure. The zonal system saves energy, cuts back on costs, and is quite functional for homes of all shapes and sizes. HVAC 1

Specific Changes to Heating or Cooling Components

Sometimes a home just needs an update in the heating or cooling department. This is the case for people living in hotter climates that need a fully functional AC unit but do not require a furnace.

Total Comfort offers all these types of HVAC upgrades to their customers. Contact us today for more info about how we can bring more heating and cooling comfort to your home!


Energy Efficiency in HVAC Units

Energy efficiency is the name of the game for modern HVAC systems. It’s one of the few excellent reasons why a homeowner would look to replace the system they already have in place completely. But, there many ways a conscientious home owner can make their older units perform better and keep their monthly bills down at the same time.

An Older Unit Can Operate More Efficiently

If you’ve noticed a spike in your gas or electric bill, there are a few things you can try before you replace the system entirely.

Change the Air Filter Regularly

Checking your air filter on a monthly basis, and replacing it if necessary is a good way to keep your costs down. The problem with dirty filters is that they slow the flow of air and force the system to work harder. That means more energy is being used and higher energy bills. Changing the filter once every three months, and checking monthly during the summer and winter, when the HVAC is working its hardest, is the best way to keep your costs down.

Yearly Tune Ups Will Pay for Themselves

A tune up for your car improves your gas mileage. A tune up for your HVAC system will enhance its energy efficiency. On top of that, an excellent HVAC service can catch minor problems before they turn into major ones. A yearly tune up will pay for itself.

Install a Programmable Thermostat

If you’re like most people, you work for a living and are generally out of the house while you’re working. That means there are large chunks of time during the day when you’re not home. Installing a programmable thermostat is an ideal way to cut your costs. It can save you around $180 yearly.

Seal Your Ducts

Forced air systems work most efficiently when there is a clear passage from the HVAC unit to the living space. If there is anything either obstructing or venting air anywhere, but in your living space, it’s forcing the system to work harder to cool or heat the room. That costs you more money, both in monthly utilities and in wear and tear on the unit.

5 Common HVAC Problems to Check For

Diagnosing Your Own HVAC Issues

Working in the business for over 30 years has taught me a thing or two about HVAC companies. Some will only try to sell you new equipment even when your old HVAC system just needs minor repairs. While it’s certainly sometimes the right choice to upgrade your HVAC system if it’s bleeding you dry each month on your utility bills, sometimes all you need is a small repair. If your HVAC system doesn’t seem to be working properly, there are a few things that you can check.

Refrigerant Leaks

What you’re looking for here is an air conditioner that seems to be blowing out warmer air. Most of the time, when that happens, it’s simply a refrigerant leak. While it’s not a major issue, it’s something that you want to have repaired because it will force the condenser to work harder and shorten the life of the HVAC system.

Compressor and Fan Failure

When your air conditioner seems not to be adequately blowing out air, this indicates a problem in the electrical wiring. In some instances, the wires have begun to corrode, and this will happen with older units, or units that are powered on and off frequently. It can be fixed without scrapping the unit.

Dirty Filters

If you notice your energy bill seems to be going up, or the quality of your air appears to be going down, one place to look is the filters. Filters should be changed once a month because the system will have to work extra hard to cool the room. A dirty filter will result in more wear and tear and higher energy bills.

Drainage Issues

If the condensation pump breaks, you may notice water pooling within or around the HVAC unit. This pooling could result in water damage to your home, and it also forces the unit to work harder making it less efficient.

Sensor Malfunctions

The thermostat triggers the HVAC system, so if the thermostat isn’t working properly, it could mean your HVAC system doesn’t know if it’s supposed to be cooling the house or warming the house. Obviously, this is bad because now you don’t have a functioning HVAC system. On the other hand, it’s easily repaired.

Our techs don’t get paid to make sales, they get paid to repair HVAC systems. So if you’re not looking to be sold a brand new unit when all you need is a minor repair contact our client specialists and let us help make your home comfortable again!



Residential A/C Units and Their Common Problems That Need Professional Repairs

With summer just around the corner, it’s the perfect time to ensure your residential A/C is working just fine. You do not want to delay if there are any pending repairs and get stuck in a hot summer with a non-functional air conditioner.

Serving the industry for the past 24 years, we have the expertise you are looking for to fix all your A/C problems.

So before you set out to look for help, find out if you are facing one of these common AC problems and if your air conditioner really needs professional repairs.

Problems with the Electric Control

There are a number of electric devices and control units that make your A/C unit functional – just like any other HVAC system. As far as your air conditioner is concerned, the fan systems, compressor, and the switches sum up as the most recognizable controls. It is very common for the connecting wires – that take care of different functions – to wear out or corrode over the period. Not paying attention to these electric control systems can damage your A/C unit and could cause total breakdown.

Leakage in the Refrigerant

Leakage in the refrigerant tops is one of the most common air conditioner problems that homeowners face. Every unit is dependent on this unique liquid known as ‘refrigerant’ to perform its cooling task. If there’s a leakage and loss of this liquid, your A/C unit will stop working efficiently. Therefore, it is essential that an adequate supply of this special liquid is always provided to the unit so that it functions properly. If you find the liquid pooling outside near the condenser, it could definitely mean there’s a leaking refrigerant.

Inefficient Thermostat

The thermostat is a significant component of your air conditioner as it provides the information that helps the unit determine the temperature it should maintain to provide cool air in your home. It’s usually the problem with the thermostat that leads to various A/C problems. You can blame the thermostat when it fails to read or maintain the right temperature. If fixing the temperature does not help you with your A/C problems, it’s an indication you need to seek help from a professional.

4 Steps to Get Your AC System Ready for Summer

Do you think to get the AC system repaired early or before summer is foolish? Perhaps you think your AC system doesn’t need it. You’ll get it inspected when there’s a need, right?

Get Ready for Summer

Beware! Sometimes, sourcing the right part takes days, and at other times, you might find out that the contractor has been booked for days in advance! *Gasp*

But before this happens, you should identify if your AC is working properly.

Follow these tips to take care of your AC to get cool, breezy summers:

  1. Check Out the Ductwork

Drywall can hide most of the ductwork. No worries, though. Some part is still open for inspection. Be sure to keep an eye out on leaky ducts as they can let allergens and dust inside your home.

Damaged insulation and rust are all signs of a less-than-average duct work. The duct can also sustain damage from innocuous-looking small animals who try seeking shelter inside. You should inspect for any odd smells coming from vents.


  1. Change the Filters

….because if you don’t, you’ll just be interrupting the airflow, which could lead to worse air-conditioning. If your home has central air conditioning, you must get high-quality filters and be sure to change after every three months.

Your lifestyle can have a huge impact on how frequently you change air filters. Turns out, if you have pets at home or kids, you should change filters every month.  In contrast, those with no pets and less frequent visitors are required to change air-conditioning filters after every 2 to 3 months.

  1. Clean the Coils

They help in movement of hot and cold air, so inspect them regularly for even cooling.

For the central air-conditioning unit, you might need to call a professional, in addition to cleaning the outdoor condenser unit.

  1. Install a Programmable Thermostat

A programmable thermostat can save you a huge amount in electricity bills by efficient cooling.

If you have a same daily routine, set indoor temperatures in advance. When you’re not home, the temperatures can be set a little bit higher but cool enough for your pets.
