What constitutes an HVAC emergency?
While a broken HVAC system is a nuisance it doesn’t always mean you need emergency repair services. For example, an air conditioner doesn’t need immediate repairs if it’s the middle of winter.
- Heat emergency: A broken furnace in the middle of a freezing Wisconsin winter would be an emergency. A fireplace or space heater may help you stay warm for a while but you will still want repairs sooner rather than later.
- Cooling emergency: A broken down A/C unit is an emergency if temperatures are high (ex: over 82 degrees) and you have no other ways of keeping cool. If you have fans or windows and the temperature outside isn’t too high you can likely wait a few days for repairs.
Homes with babies should be kept somewhere between 65 and 75 degrees since infants cannot regulate their own body temperature. For these families, almost any HVAC problem will be considered an emergency.
What is an Energy Star Rating?
An Energy Star Rating is a US government rating given to products and practices which meet or exceed specific guidelines on energy consumption. Products with the Energy Star label effectively help to reduce greenhouse gas emissions and save the users money on their energy bills without any reasonable loss in performance. See Donovan & Jorgenson's Energy Star Products.
Why is my drain hose filled with black stuff?
Your hose will build up with dirt, debris and sometimes algae over time. Flush it with a strong bleach water solution or replace the hose.
Why are my windows wet?
Condensation on your windows is usually caused by stagnant air. Keep air circulating with a furnace blower fan.
I have dry sinuses, my woodwork is splitting, and my carpet is shocking me. What gives?
Your home is too dry. Add a household humidifier to fix the problem.
How often should I service my heating and cooling equipment?
An annual tune-up for your furnace and air conditioning system will be sufficient. Your furnace equipment can be tuned up any time of year and does not have to be done before the start of the heating/cooling season, if you keep up with regular maintenance. Air conditioning tune-ups need to be performed when the outside temperature is above 60 degrees.
How can I conserve energy and reduce my bill?
Invest in energy-efficient appliances - save money and help the environment.
- Air conditioners up to 19 SEER efficiency rating
- Furnaces up to 98% efficient, look for at least 95%
- Geothermal heat pumps maintain the highest efficiency on the coldest winter night or the hottest summer days
- Gas or electric dryer booster fans shorten drying times reduce energy usage and costs and avoid excessive wear and tear on your dryer
- Programmable thermostats can save up to 20% on your heating costs
- Area-by-area zoning – subdividing your house into different temperature zones can help conserve energy
- Whole house humidifiers allow homeowners to reduce the thermostat setting 2-3 degrees
What size should my furnace or A/C be?
This question is best answered by a professional on a home visit. Many factors affect the accurate sizing of an HVAC unit including:
- Size of the space
- Orientation of the home
- Ceiling height
- Window efficiency
- Age of the home
My A/C unit is low on Freon. What is happening?
If you notice your unit is low on Freon, either it was never filled properly or it is leaking. When your system loses refrigerant, the performance suffers. The system can freeze, and cause more problems down the line. Contact a certified Milwaukee HVAC professional from Donovan & Jorgenson.
