HVAC Maintenance Plans for Homeowners
Nothing is worse than having your air conditioner fail on a hot day in the summer, or having your heater fail in the dead of winter. That’s why we offer routine preventative maintenance plans for residential customers that can find and fix potential problems before they occur.
Our maintenance plans include tasks such as:
- Flushing the drain
- Add Clorox tablets to the drain for mold prevention
- Check Freon levels
- Clean the coils
- Inspection of the unit
We recommend that for units two years old or older, you have them inspected at least once a year. This is especially true if you use natural gas, because frequent inspections could detect a gas leak early on before it becomes dangerous.
Common Heating and Cooling Systems for New River Valley Homeowners
There are many methods for heating and cooling a home, but in our service area some methods are more common than others. The most common combinations we see are:
- A gas furnace with a heat pump
- A gas furnace with air conditioning only
- Heat pump with electric backup
There are many factors that will affect which method is most energy efficient for any given home, including the size of the home, whether or not the home has natural gas available, and the age of the home. Air Tech can give you advice about which combinations of methods would make the most sense for your circumstances.
Tankless Water Heater Installation and Repair
A “tankless” or demand-type water heater provides hot water only when it is needed, instead of continuously heating a large tank of water. This could potentially save you money on energy costs depending on your situation.
The diagram below from the Department of Energy shows the basic elements of a tankless water heater.
With tankless water heaters, when the hot water tap is turned on, cold water flows into the unit and is heated by a gas burner or electric heating element.
Because the hot water has to be heated as it flows through the unit, the flow rate is limited to 2-5 gallons per minute. Sometimes, this may not be enough for large households--for example, if multiple people are showering at the same time, there might not be enough hot water for everyone.
To get around this problem, you could install multiple tankless water heaters that run in parallel or install separate tankless water heaters for certain appliances like dishwashers that use large amounts of hot water.
The advantages of a tankless water heater include:
- They can be 8%--14% more energy efficient for homes that use 80-90 gallons of hot water a day
- They have easily replaceable parts that can extend their life beyond 20 years, compared to 10-15 years for storage water heaters
- Energy Star qualified tankless water heaters can save the average family $100 or more a year

Residential HVAC Frequently Asked Questions
Below are some answers to questions we frequently get asked by our residential customers.
Do you offer WiFi thermostats?
Yes, we can install Wifi thermostats that allow you to change your thermostat setting from anywhere.
What temperature should I set my thermostat at?
Most people find that a temperature of around 72—75 degrees is comfortable. If you want to save energy when you are away from home at work during the day, you can raise or lower the thermostat setting by about 4 degrees. If you change it by any more than that, the energy savings will be mitigated by how hard the system has to work to get the temperature back to the original setting.
How often should I change the filters on my system?
For standard filters, you should change them about once a month depending on how clean your home is and whether or not you have pets. In the case of whole-house HEPA filters, they only need to be changed about once every 6-12 months.
How often should I have my HVAC system checked?
We recommend that your system be inspected once a year if it is older than 2 years. This will help detect problems early-on when they are less expensive to fix, and also prevent common issues like mold build-up before they even occur.
