Common Problems with Gas Water Heaters

Are you having trouble with your gas water heater? Problems can range from a pilot light gone out to the need for replacement. Here are a few common problems with gas water heaters:

Pilot Light is Out

problems with gas water heatersOne of the most common problems with gas water heaters is that the pilot light will go out, leaving you with no hot water. If you turn on the shower and it won’t get hot, check your water heater. Be sure to follow the proper method of lighting the pilot light if it is out. If it won’t light, make sure the gas valve is in good shape and then check the thermocouple.

Bad Thermocouple

A bad thermocouple can cause various problems with your water heater. You might not be able to get the burner or pilot light to work. If you decide to replace this part yourself, follow all proper safety precautions when handling your water heater! Otherwise, call a skilled HVAC technician to repair your water heater.

Leaking Water Heater

If your water heater is leaking, there is a serious problem and you’ll likely need to replace it. Most conventional tank-style water heaters last about 10-15 years. However, hard water, poor maintenance, and other problems can shorten its lifespan. Call a technician right away for water heater repair or else you could risk flooding and damaging your home.

If you face any of these problems with gas water heaters, call Sanders & Johnson Heating and Air Conditioning at 303-422-6606. We’re happy to provide water heater repair and replacement in Denver, CO!

Ductless Mini-Split Heat Pump, Are There Benefits?

Are you considering a ductless mini-split heat pump for you home?

A great addition to any space, there are many benefits of a ductless mini-split heat pump: Like central air and heating systems, ductless mini splits have two main components: an outdoor compressor/condenser and an indoor air-handling unit. A conduit connects the outdoor and indoor units.They are high efficiency air conditioners that can also operate in reverse to heat your home.

Compact Size

Compared to window units, ductless mini-split heat pumps are much more compact and versatile. You can hang the indoor unit from the ceiling or on a wall, and there are even stand up models. This not only increases your interior design options, but also provides greater safety. Even the outdoor unit is fairly small.


A big draw for many homeowners is the green features of a ductless mini-split heat pump system. These systems can reduce your electricity use by about 50 percent compared to a traditional furnace. Plus, because it is ductless, you will not lose or waste energy through poorly insulated ductwork.

Double the Benefits

Another great benefit  is that it can function as an air conditioner or heater. Because it does not produce heat—only moves it from one place to another—the heat pump can do both. Plus, you can install multiple indoor units for only one outdoor unit. With individual thermostats, this lets you control the temperature of multiple zones in your house. Enjoy the flexibility and efficiency of a ductless mini-split heat pump today!

heating bill

Some people may think that it necessary to constantly crank up the heater or the furnace to make sure that they stay warm.  That will just increase your heating bill. Although turning on your heater is an obvious choice for one that desires to stay warm, you have to put up with outrageous heating bills during this cold season. The pros at Sanders and Johnson Heating and Air Conditioning are here with some tips that will help you save on your heating bill throughout the season.

Here are just a few suggestions — but if you need something more call Sanders & Johnson!

  • Insulation for the attic door: Even if your attic has adequate insulation, chances are that the access door is lacking and is allowing warm air to escape through the hatch. To make sure that your attic door is effectively blocking airflow, trying attaching fiberglass batt insulation.
  • Cover your windows with a plastic film: About 25 percent of heat loss in your home can be contributed to your windows and patio doors. Adding a transparent, plastic film can assist in reducing that loss. It’s inexpensive, easy to install, and even easier to remove once the weather begins to warm up again.
  • Prevent warm air from escaping through your chimney: Even with the flue closed, heat can escape through your chimney. A simple solution is a chimney balloon. Putting one of these in your chimney helps to stop unwanted airflow and helps to save as much as $100 in a year on your heating bill.

We understand that saving money is important to any property owner. So if you need help or have any questions on how you can save money on your heating bill in Denver, contact Sanders and Johnson Heating and Air Conditioning.

Seasonal Heater Maintenance with Sanders and Johnson

Regular air conditioner and heater maintenance is always a good idea, especially when the weather changes. If you don’t check your air filters often, the beginning of each new season is a good time to do it. With chilly air already hitting Denver, you may be ready to fire up your heater. Before you do, follow these quick HVAC maintenance tips to keep your system running well.

Heater Maintenance: Change Your Air Filters

heater maintenance

You should check your air filters once a month for built up dust, hair, and other particles. Don’t wait until they are clogged up; this can cause your HVAC system to perform at sub-optimal levels. As your system pumps cooled or heated air throughout your house, the filter catches dust, allergens, spores, and other nasty particles. Regularly changing the air filter will help keep your home air cleaner, may improve your allergies and asthma, and reduce your energy bill.

Have A Test Run

Before the really cold weather hits, give your heater a test run to make sure everything is working properly. As it sits unused over the summer months, dust builds up in the furnace filter and in your ducts. Have you ever noticed a burning smell when you first turn on your heater after months of disuse? This is the dust burning off, and is no cause for concern. However, if the smell does not go away within an hour, or if it smells electrical, turn the heater off and call a professional HVAC contractor as soon as possible. You may need heater maintenance or repair.

Clean Up The House

The cleaner your home, the less dust and dirt will make its way into your air conditioner or heater. We’ve all heard of spring cleaning, but a deep clean may be necessary in the fall too. This is especially important if you have pets or several people living in a home. Vacuum, dust, and mop thoroughly. Don’t forget the spaces beneath or behind furniture!

Faulty Air Condition Wiring: Common A/C Problems


Common Problems with A/C could be Faulty Air Condition Wiring

Are you having problems with faulty wiring in your air conditioning unit?  Did you know that this can be hazardous to your family home? Here are a few indications of bad wiring that you can look for and determine whether it is time to have it repaired.

faulty wiring in thermostat

Exposed wires around the A/C unit are typically seen with an improper installation of an air conditioner.  Bad wiring is not only a fire hazard, but it can allow moisture into the unit. Faulty wiring can also create the need for some expensive repairs. At Sanders & Johnson’s one of our professional service techs will come out to fix the exposed wiring.

If your circuit breaker keeps getting tripped when the air conditioner tries to run, you might be a problem with the wiring inside the unit.  If the breaker continues to trip, don’t keep switching it back on because this will just cause more damage to the unit and the wiring. Another cause of the breaker being tripped may be a dirty air filter or blocked airways. This can be checked and cleaned up quickly without needing any repairs.

Another place to look is the thermostat.  Your thermostat could be a source of faulty air condition wiring, especially if it has not been properly maintained through the years or if it is an older model. You can upgrading an older model but that doesn’t always fix any faulty wiring issues.  However, it can  make it easier to make cooling your home more energy efficient.

Air Conditioner Efficiency: Save Money

Get the most from your air conditioner during the summer months: Air Condition Efficiency is the answer.

Lower costs this summer by improving the efficiency of your air conditioner. Doing a little maintenance around the house will help to cut down on your utility costs.  It can also improve the air quality in your home. These tips to improve the efficiency of your air conditioner will help you save money without having to buy a new air conditioning unit.

Air Conditioner EfficiencyLimit Use of Large Appliances

When you use the large appliances in your home such as the dishwasher, oven, washer or dryer, you are actually generating even more heat inside the house.  Here is a helpful hit:  Use these appliances in the morning or late at night.   Temperatures are cooler in the morning and in the evening reducing the overload of running the air conditioner.  if you use them during the hotter times of the day it will make your  air conditioner work even harder to try and keep the house cooler.

Make Repairs to Improve Insulation
Take a look around the house, do you see any cracks?  If you do seal them with caulk to prevent drafts. Any cracks in the walls or ceilings will allow the cooled air to escape.  This requires the air conditioner to run more frequently to keep the rooms cooled.. Making sure your windows are insulated can reduce your energy costs by 25-50%. You can use weatherizing tape around the windows and doors to seal any gaps that also allow air out.

Schedule An A/C Inspection
Scheduling an inspection once a year from a licensed air conditioner technician can help prevent many potential issues with your cooling system. A technician can make small repairs to leaks or other damage that may cause your A/C unit to work less efficiently. They can also clean the air duct system and replace air filters to improve the air quality.

Increase Air Circulation
Try using ceiling fans during the day to help cool air circulate throughout the house so the air conditioner runs less often. The ventilation fans in the kitchen and bathrooms can help with this to by reducing the heat and moisture in those areas.

These are just a few ways you can get your air conditioner running efficiently. Call Sanders & Johnson, Inc. today for preventative maintenance and air conditioner inspections in Denver, CO.

Air Filters – 3 Reasons Your Furnace Isn’t Pumping Out Enough Heat

Why are you so cold? Do you need a new furnace? Maybe just Air Filters!

dirty air filtersIt’s a nasty surprise no homeowner wants to deal with the changing of the air filters. The temperatures plummet outside, and when it comes time to fire up the furnace, not enough heat is coming out.  Brrrr?

So, why isn’t your furnace producing enough heat? It could be due to any number of issues, including:


Here are just a few reasons that you may be experience issues with heat flow.

Dirty air filters — When your filters are dirty, it blocks proper airflow and makes it difficult for your furnace to properly heat your home. Experts recommend changing your filter out at least every 3 months to maintain proper furnace function. So, if you haven’t swapped out your filters in a while, this is a good place to start.

Leaky ducts — If your ductwork has cracks and poorly maintained seals, heat can escape before it gets delivered into your house. This makes your home colder, and it forces your heater to work harder, causing excessive wear and tear.

Undersized furnace — One common reason for poor furnace performance is that the system isn’t the right size for the home. It’s possible that your furnace may simply be too small and too weak to properly heat your home.

If your furnace isn’t producing enough heat, contact the Denver furnace repair experts at Sanders & Johnson. We offer reliable, honest furnace maintenance services at affordable prices to homeowners across the Denver area. Learn more at Like us on FaceBook.
