What Are the Benefits of a Geothermal System?

Friday, October 31st, 2014

Choosing a new air conditioning or heating system can be a difficult process considering all of the options available in today’s world. But if you need a new heating and cooling system, it’s tough to beat the efficiency of a geothermal system. Geothermal heat pumps depend on the stable temperature beneath the earth’s surface to circulate heat. Learn more about these systems in this guide.

Roznovak is your professional source for heating and air conditioning installation or any residential AC service here in Los Angeles.

How It Works

A heat pump is a type of system that moves heat from one area to another. In an air-source heat pump, refrigerant pumps through an indoor and outdoor component to move heat from the inside to the outdoors in the summer and from the outside to the inside in the winter. A geothermal system works a bit differently. Water or a water-refrigerant blend pumps through a set of coils buried underneath the ground. In the heating season, heat is absorbed from the earth and moved into your home. In the summer, heat is absorbed from the air in your home and safely deposited outdoors.

Some Benefits of Geothermal Air Conditioning and Heating

  • Environmentally Friendly: Many people praise geothermal heating and cooling for its low environmental impact. Geothermal heat pumps do not release pollutants into the air and use far less power than standard AC and heating systems.
  • Energy Efficient: Geothermal systems are incredibly efficient, saving a lot of money from month to month. In fact, as time goes on, the energy savings combined with the possibility of government incentives can offset the initial cost of installation.
  • Fewer Repair Needs: Generally, geothermal systems require fewer repairs than some other types of heating and cooling systems because they contain few moving parts and because the outdoor components are buried underground, and not exposed to the outside elements.

Geothermal systems are also relatively quiet, have long lifespans, and you may receive local or federal incentives for installing the system. Geothermal systems are great for anyone looking to save money from month to month and retain quality heating and cooling.

Ways You Can Update Your Current Air Conditioning System

Friday, October 24th, 2014

Your air conditioning system does a sufficient job at providing cool air to your home when you need it. But if you’re not getting quite the performance you deserve from your home comfort system, there may be a few changes you can make that will keep you more comfortable, save some money, and even improve the quality of your air.

You know to call a professional whenever you need residential AC repairs. However, the following services are some other ways you can update your air conditioner for a more relaxing home. These require the help of a professional technician, but can help prevent repairs and save you time and money later on.

  • Thermostat Upgrade: Thermostats have an important job: detect the indoor temperature and send a signal to the air conditioner when the temperature is higher than you have set the thermostat. It may seem that all thermostats work the same way, but a new thermostat can help you save energy and ward off repairs. A programmable wireless thermostat can be placed anywhere and has a digital display and advanced settings so that you can vary the temperature throughout the day. A smart thermostat can operate with an internet connection from a computer or smartphone. Controlling the temperature throughout the day keeps costs down and stops your system from becoming overworked and requiring repairs.
  • Zone Control Installation: Zone control systems allow you to adjust the temperature differently in individual areas or zones of the home. Separate thermostats mean family members are more comfortable wherever they are in the home, and it can help you save energy. You can shut off the air in areas of the home that go unused throughout the day, while keeping it on in the main living spaces.
  • Air Filtration System: An air filtration system can keep the air indoors feeling less stale, and can help keep allergies and asthma from acting up by filtering out certain harmful particles, bacteria, and mold spores. Try a new UV air purifier, dehumidifier, or electronic air filters.
  • Professional Maintenance: Finally, you can update your air conditioner by making the call to a professional technician for annual air conditioning maintenance. A technician will inspect the parts of your system, clean some components, and make minor adjustments to keep your unit running in the best shape possible.

Common AC Repairs

Friday, October 17th, 2014

We are at the tail-end of another cooling season, and it’s not unusual for you to see some problems arise with your air conditioner. After several months of operating around-the-clock, your system is bound to have some wear and tear, and you may need to schedule residential AC repair service. There are some repairs our Roznovak technicians see at this time of year more than others, but for any repair you may need, call the experts at Roznovak.

Here is a List of Common Air Conditioning System Repairs

Compressor Problems

The compressor in your air conditioning system operates under a lot of pressure in order to do its job. Operating full time, it isn’t unusual for certain problems to develop. Common issues are electrical problems, particularly with wiring and capacitors, and problems with the motor; oil leaks can also develop. Your compressor is a complex component, and any repairs involving it should be handled only by a trained professional.

Refrigerant Leaks

Your air conditioner needs to run with an exact amount of refrigerant, as specified by the manufacturer. When leaks develop, they lower the level of refrigerant in the system, and as such, create an imbalance in the heat release/cooling process. Refrigerant leaks can develop in a number of places, and are challenging to detect unless you have training. If you suspect you have a refrigerant leak, call for professional assistance.

Fan Issues

The fans in your system help with air flow. Typical fan problems are problems with the motor, electrical issues such as frayed wiring and problems with loose or bent fan blades. Because of the variety of issues that can develop with the fans, it’s important to hire a trained technician to inspect and determine the exact problem rather than handling things yourself.

Your air conditioner works hard during the summer months, and while it may be tempting to just turn it off at the end of this cooling season, it’s always better to attend to any existing problems as soon as possible. Call Roznovak today and schedule your residential AC repairs in Round Rock, TX.

What Is an Energy Recovery Ventilator?

Friday, October 10th, 2014

Energy efficiency is important for you and your home. But sometimes a home can be so airtight that ventilation is compromised. While throwing open a window helps with ventilation, this isn’t a great option when you are heating or cooling your home. However, there is an upgrade you can add to your HVAC system that can provide healthy ventilation while also saving energy: an energy recovery ventilator. An ERV brings fresh air into your home without compromising the heating or cooling, and helps save energy while it does this. ERVs are great devices, which is why we offer them as part of our heating service in Hutto, TX. It’s important to hire only trained professionals when installing an ERV, and the expert technicians at Roznovak are ready to help.

How Does an ERV Work?

The genius of an ERV lay with its core: the heat exchanger. This exchanger exhausts the stale air from your indoors while using the energy from the stale air to pre-treat the incoming fresh air. During the winter months, your stale, heated indoor air is sent to the outside, but the energy from this air warms the incoming cool, fresh air before it enters your home. In the summer, the stale, cool air from your home exits to the outside, but the energy from it is saved to cool and dehumidify the incoming warm air.

Benefits of an ERV

There are several benefits to installing an ERV:

  • Less wear on your system – ERVs help reduce the workload on your air conditioner by pre-treating the incoming air. This means your system can do less work to achieve your set temperature. Less work means less running, which reduces the wear and tear on your system.
  • Improved indoor air quality –an ERV provides constant fresh air to your home. This helps keep clean air circulating throughout your home, maintains humidity levels and improves the overall indoor air quality.
  • Increases energy efficiency – the pre-treating of the indoor air helps to increase the energy efficiency of your system.

If you’ve been looking for a way to have better ventilation in your home while increasing energy efficiency, an ERV may be just what you need. Call Roznovak today and schedule an appointment to discuss how this residential heating service in Hutto, TX may be able to help you.

3 Benefits of Scheduling Heating Maintenance

Friday, October 3rd, 2014

Leaving the heating system alone until it starts manifesting problems is a very common attitude among homeowners. It can also cost you thousands of dollars a year. Preventative maintenance is always cheaper than repairing or replacing a broken part. Cost isn’t the only factor to consider, either.

Read on to discover 3 benefits of scheduling heating maintenance.


Not all problems with your heating system will give you warning before causing the entire unit to break down. If you wait for some sort of sign before calling your HVAC technician, you may get blindsided with a broken system and an expensive repair bill. This could be especially bad in winter, when going without heat for even one day is a very uncomfortable thought.

Scheduling regular heating maintenance gives you the advantage of addressing minor issues before they become big, expensive problems. You can also have the peace of mind that comes with knowing that your heating system has a clean bill of health.


As mentioned above, an ounce of prevention is worth a pound of cure. Little problems that can be easily fixed at first can grow into very expensive problems in short order. This is especially true of parts that the rest of the system relies on. Broken motor? The whole system is useless. Malfunctioning thermostat? Even if the rest of the system is perfectly fine, it won’t work. On top of all that, many manufacturer warranties require that you conduct regular maintenance in order for them to remain valid. If you neglect your heating maintenance and something goes wrong, you may end up paying entirely out of pocket.


There are some occasions where your heating system will display symptoms of a problem before breaking down entirely. That doesn’t mean that you can just ignore those symptoms, however. Even if the problem does not intensify, which is unlikely, you will experience a drop in efficiency from the unit. This can cause your utility bill to go up, as the unit has to work harder to do its job. Proper maintenance saves you from those high utility bills because of a malfunctioning unit.

If you haven’t had your heating unit checked this year, call Roznovak. We’re experts in heating maintenance in Taylor, TX.
