Q2. What should I do if I am smelling gas?
- Immediately leave your residence.
- Do NOT turn any lights on or off, touch any switches in the home, or any other electronic devices as these can all be sources of fire ignition.
- Do NOT use the telephone inside your home.
- Go to a neighbor's house or use your cellular phone once you have left the residence and immediately call the fire department to evaluate the situation and determine if the property is safe to re-enter.

Once they determine where the leak is you can then contact our office to schedule an appointment for one of our technicians to repair the leak.
Q3. What is the average lifespan of an HVAC system?
The average lifespan of central air conditioners and heat pumps is approximately 12-15 years. Furnaces can last much longer with proper care, however, technological advancements generally warrant the need for replacement within the same time frame. It is also more cost effective to replace your entire HVAC system at the same time rather than replacing individual units on separate occassions.
Q4. How can I extend the life of my system?
"An ounce of prevention is worth a pound of cure". To best maintain the integrity of your system you want to make sure that you schedule annual check-ups for both your heating and air conditioning systems; once during the spring season for your air conditioner and again in the fall season for your heater. Also, be sure to change your filter regularly every 1-3 months, on average. If someone in your home has been sick with an airborne illness (influenza, the common cold, strep throat, etc.) you may want to change your filter as soon as the illness has been treated so that the germs do not continue to cycle through the ventilation.
Q5. How often should I change my filters?
Your filter should be changed regularly every 1-3 months, on average. If someone in your home has been sick with an airborne illness (influenza, the common cold, strep throat, etc.) you may want to change your filter as soon as the illness has been treated so that the germs do not continue to cycle through the ventilation.
Q6. What should I do if my heater or air conditioner is making an unfamiliar sound?
Take note of what kind of sound your unit is making. Shut the system off and call Summit Heating and Air Conditioning at 302-378-1203 or 410-398-3233. There can be a variety of reasons why your unit is making a different sound and needs to be diagnosed immediately by a professional.
Q7. What should I do if my air conditioning unit is frozen?
Shut your air conditioner off as soon as you notice that it is no longer cooling or is beginning to cool less effectively and then call Summit Heating and Air Conditioning at 302-378-1203 or 410-398-3233 to schedule an appointment with a technician. The unit needs to thaw out before the problem can be diagnosed and repaired. If you do not get an appointment the same day that you noticed the unit freezing up you can let your unit thaw overnight by itself but do NOT turn it back on before the technician arrives. If your appointment is the same day it is recommended that you switch your thermostat dials from "COOL" to "OFF" and also from "AUTO" to "FAN". By following these steps your unit should thaw out quicker and allow for the technician to properly diagnose and repair the problem.
Q8. What if my heater is not running at all?
If your heater is not running there are a few things you can do before scheduling an appointment for repair.
- Check to see that the main switch to the unit is on. If the switch is off simply turn it on and this should rectify the situation.
- Check your breakers. If they have been flipped then you should just need to flip them back.
- If there is snow on the ground you are going to want to check your outside vent pipe to make sure the area is clear from snow. If snow is blocking the opening of the vent pipe not only will it cause your system to not operate but can be dangerous, causing carbon monoxide to back up into your home.
If after checking all of these recommendations your unit continues to not operate call Summit Heating and Air Conditioning at (302) 378-1203 or
to schedule an appointment for a technician to come to your home and diagnose and repair the problem.
Q9. Should I cover my outside unit in the fall and winter months?
It is recommended to cover your outdoor unit during the months that it is not in use. However, you want to make sure that you only cover the very top portion of the unit to keep debris from falling into it. You want to leave the sides open to continue to allow airflow through the unit. Inhibiting airflow could cause irreparable damage to the unit.
Q10. What does SEER mean?
Seasonal Energy Efficiency Ratio (SEER), simply put, is a measurement of efficiency for air conditioning systems and heat pumps. The higher the SEER is the more efficient the unit is.
Q11. What does AFUE mean?
Annual Fuel Utilization Efficiency (AFUE) is a measurement of efficiency for a heating unit. The higher the AFUE rating the more efficient the unit is.
