The Tools that we use!
Homeowners expect heating and air conditioning contractors to have the training and knowledge to deliver the Energy Efficiency rating of the Heating And Cooling System they spent their hard-earned money on. Unfortunetely, for the majority of contractors simply don’t know how to provide this service, many simply don’t care! Want proof? Ask if any one of these instruments are in their tool box!
(MRI) Thermal imaging Camera
The Interior -Thermal Camera With an MRI, doctors use the results of the scan to see where serious conditions exist with their patients and then make informed decisions on how to proceed. Home Energy Experts uses a Thermal Imaging Camera (MRI) to scan the interior of a home and to see behind the walls, floors, and ceilings where you might be losing conditioned air and allowing outside air to enter your home. With this never before seen information, it helps us solve your heating and cooling problems.
Air Leakage (Infiltrometer) Blower Door
Outside air that leaks into and out of your home will cause hot air, cold air, and hunmidity to enter and exit your home. Often times this can be harmful or even just dirty to you and your home if that air has to pass thru crawl spaces, attic spaces or garages. We always ask ourselves while testing homes, “where is all the expensive heat or cooling going?” A home that has a tighter envelope, “one with less air leaks” will require less heating, less cooling, less need for added humidity, and be a home with much cleaner air.
Electronic Air Flow Hood
Air flow is the life blood of your heating and cooling
equipment. Electronic Air Flow HoodHow does each room in your home measure up for its heating and cooling demand needs? Your Home Comfort Advisor will use an air flow hood instrument to measure precisely how much conditioned air is getting to each room (provided floor registers and ceiling vents are accessible). If air flow is inadequate, he’ll recommend upgrades that will address problem areas.
Ductwork Delivery Capacity
Every time you visit your doctor, he performs a blood pressure test to check your physical condition. If your test shows your blood pressure is high, your doctor recommends further tests to help you lower it. Like your doctor, we at Nevada Heating and Air analyze your ductwork for its overall condition; our test is called static pressure. If our test shows your static pressure is high in your ductwork, we will recommend solutions to improve it.
it’s our professional experience that properly sized, installed, sealed, and insulated ductwork will reduce your energy cost and make your home more comfortable. Our “Lifetime Ductwork Guarantee” is: Should any part of the ductwork that we have installed or repaired develop a leak, we will repair the problem FREE –both parts and labor — for as long as you own your home.
Analyzing the Attic Insulation
Using our (MRI) Infrared Thermography camera, we can pin-point areas in your attic (red shows areas in the summer and blue shows areas in the winter) where problem areas exist. The amount and quality of the insulation in our attic dictates how hard your heating and cooling equipment has to work to heat and cool your home properly. The EPA estimates homeowners can typically save up to 20% of heating and cooling costs (or up to 10% of total energy costs) by adding insulation in attics and floors over crawl spaces.
In Northern Nevada (Zone 5), the recommended insulation value is: Attic-R38 to R60, Cathedral Ceiling-R30 to R38, Walls-Rl3 to R19, Floors-R25 to R30.
Furnace Combustion Analysis
With a Combustion Analyzer, Nevada Heating and Air can analyze the true running efficiency of your furnace. Standard furnace contractors stop when they plug it in and get it running. But, just like a car, a furnace can be running but not be delivering the best “mile per gallon,” so to speak. Combustion balancing takes a furnace after it is installed and optimizes its burning efficiency to both make sure it is burning safely (low carbon monoxide output to the flue exhaust) and that the fuel being burned is producing the highest level of BTUs (efficiency!)
There’s an old saying in our industry… Air Conditioner “The most important day in the life of your air conditioner is the day of its startup”. For many air conditioning contractors, if you mention “instruments” it scares them because it costs too much, or it takes too long to learn how to use them. Hog wash! It’s obvious they don’t have to pay your higher than normal utility bills or replace the compressor when it fails.
It takes sensitive temperature instruments to monitor both outside and inside temperature and humidity levels to properly balance the refrigerant levels on an air conditioning system. Calculations are then performed after the airflow test to make sure the air conditioner is producing peak BTU delivery efficiency. This procedure takes time and is seldom done on a new air conditioner start up due to cost of the instruments, lack of time, and the installing contractor’s not wanting to spend the extra labor to do so. Often times installing contractors do not even know how to perform this type of air conditioner start up balance.
Our Home Comfort Advisor will use an electronic air thermometer to verify the temperature being delivered at the floor registers or ceiling vents, and the air temperature coming from your heating and cooling equipment. If the air temperature doesn’t meet manufacturer’s standards, he will determine the problem and appropriate upgrades will be prescribed. It is not uncommon for the temperature at your registers to be much less (heating) or higher (cooling) than the temperature directly leaving the heating and cooling equipment.
The Duct Blaster®
Is there a thief in your home? The Duct Blaster
The thief I’m referring to is the hidden maze of gray, black, soft squishy flexible ducts or un-insulated and poorly sealed ductwork. Its function is to carry expensive hot and cold air from heating and cooling equipment throughout a home. If your home has this type of ductwork in your attic or crawlspace, you could be experiencing a great deal of hot air loss in the winter and cold air lost in the summer from your furnace or air conditioner. The larger problem is that if these ducts have holes in them, outside air is moving in and out of your home carrying away your expensive heat or air conditioning! It’s like leaving the door open! This air often travels through dirty crawl spaces or fiberglass insulated attics and ends up inside your home.
The Duct Blaster® involves pressurizing the ductwork with a calibrated fan and simultaneously measuring the air flow through the fan, and its effect on the pressure within the duct system. The tighter the duct system, the less air you need from the fan to create a change in duct system pressure. Testing procedures can be set up to measure only ductwork leakage, which is connected to the outside of your home, or to measure total duct defects. Ductwork testing helps us diagnose and demonstrate ductwork problems, and estimate heating and cooling operating cost overages.

Load CalculationsLoad Calculations
Nevada Heating and Air performs an industry standard room by room computer generated calculation that pin points the exact size of the furnace and air conditioner needed for your home. Correctly sized furnaces and air conditioners are very important not only to obtain perfect comfort in a home, but to use the least amount of gas and electricity. By accurately measuring the home’s living space, the layout of the floor plan, which way windows and doors are facing, the number of stories the home has, the amount, type, and condition of the homes insulation, Nevada Heating and Air can identify if your existing equipment is either too big, or too small, thus wasting your hard earned money because of improper sizing.
Bigger is not better
It’s not uncommon for HVAC contractors to size furnace and air conditioners by the square footage of a home. The problem with this “rule of thumb” mentality, it doesn’t take in the fact that each room of your home has a different heating and cooling need because of its location to the sun. Oversizing the furnace or air conditioner occurs so often in our industry most due to the installing contractor not understanding how much heating or cooling the home really needs. Compile that with the installing contractor also not understanding how the duct work relates to delivering that heat and cooling from the equipment to the homes rooms.
