Heating (48)

As the cold winter weather arrives in West Haven, CT, and the surrounding region, some homeowners will find themselves with a furnace that won't turn on. 

Before you call Air Specialties for service, there are a few things you can check yourself.

  1. Ensure That the Power Is On. Even though it's gas powered, a furnace requires electricity to run, so check the power to the unit at the circuit breaker panel. If a circuit is tripped, switch it back to the ON position. Note, if the circuit trips again, DO NOT RESET IT MORE THAN ONCE. This is a safety measure to prevent an electrical fire in the event of a malfunction. Have an electrician inspect the system.
  2. Check the Thermostat Is Turned To the HEAT Position, then try turning the temperature up a couple degrees for testing purposes.
  3. Check the Furnace Condensate Pan (Drain Pan). During normal operation, water will drain from the air conditioner or furnace into a pan. If the drain for the pan is clogged, the pan will fill up and trigger a float switch, preventing the operation of the furnace. If the float switch is up (activated), you will need to clear the obstruction to allow water to empty and then reset the switch.
  4. Check the Furnace Filter. An extremely dirty and clogged filter will make the furnace overheat, which will cause it to shut down as a safety precaution. Install a new filter to allow it to breathe easier.
  5. Check the Pilot Light. This only applies to older gas furnaces. Most newer units have an electric ignition. If your pilot light is out, consult your owner's manual for the correct way to light the pilot.
  6. Check the Fuel Supply. If there are other gas appliances in the home, such a gas range or fireplace, check that they are functioning.

If none of the above steps works and the furnace still won't turn on, call Air Specialties Air Conditioning and Heating. We have experience working with all makes and models and can provide prompt, reliable service throughout West Haven, CT, and the surrounding region.

Whether you are heating a home or a business, your oil boiler can fail for several reasons. As a reputable provider of boiler repair services in and around Milford, we've created this piece so that our customers can spot the signs that indicate that their boiler needs repairs.

Equipment is Old

Like all mechanical equipment, boilers wear down over time and require maintenance and repairs. If your equipment is older than 15 years, it may very well be time that you consider a replacement.

Strange Smells

Damaged boilers tend to leak. If your boiler is leaking oil, you may notice an egg-like or metallic smell. Although carbon monoxide is odorless, many gas suppliers add sulfur to make the gas give off an odor and be detected easily.

Power Faults

If your boiler doesn't run after it has been switched on, there could be a power supply problem. A technician will be your best bet for getting to the bottom of a power issue problem quickly and efficiently, especially during the colder months.

Delayed Heating

When a unit is functioning efficiently, heat should be produced very quickly after switching on the boiler system. If it starts to take longer and longer for your boiler to produce heat, you might have a circulation issue. You may also notice your unit shutting down frequently to avoid overheating.


In most instances, the issue can be solved with a single repair, but sometimes a newer, more advanced model is necessary.

Insufficient Heat


When your boiler is producing heat, but your home or office never seems to reach the predetermined temperature, there could be a heat delivery issue. These issues can be caused by many variables, including short circuits in the thermostat, or buildup inside the tank.

When you run your boiler, check the thermostat settings. If your building fails to reach the desired temperature, it’s time to call a professional.

As a trusted heat pump and furnace repair company serving North Haven and surrounding areas, we’re often asked the question, “How long will my ductless heat pump last?” We’re sure that this is a question a lot of homeowners want to know the answer to. For that reason, we’ve created this post to briefly explain some things about the longevity of this heating system.


Ultimately, ductless heat pumps can last for between 5 and 20 years — depending on many factors.

Why do some machines last longer than others?

It’s down to the quality of the materials used to manufacture the heat pump. Quality craftsmanship and components go a long way in ensuring the machine that works with high levels of heat can stand the test of time.


Brands such as Mitsubishi, Fujitsu, and Daikin are all reputable manufacturers to consider when looking for a new ductless heat pump.

How do you know a machine is built to last?

It’s simple, check the length of the company warranty on any model that you want to buy. If the guarantee extends to 12 years or more, it’s a safe assumption that the machine will work for at least this length of time without worry.

Can price indicate the lifespan and durability of a ductless heat pump?

Many high-quality brands are very efficient. If you’ve done your homework and researched several different heat pumps, you may have seen the correlation between price and quality. For this reason, it’s a safe assumption that cost is a valid indicator of longevity when it comes to these products.


That said, many people still choose to buy cheap, less reliable products.

Why You Should Avoid Lower End Unit Purchases


Let’s imagine that you pay a heating company $2,000 for them to install a heat pump one weekend, and this heat pump has a 4-7 year lifespan.


Now, let’s imagine that one of our HVAC professionals came out and fitted a brand new, state-of-the-art Fujitsu heat pump for you with a 12-year warranty.


With the number of repairs and maintenance you may have to pay for the first machine; you’ll save money installing the second option. With premium units being more efficient, you’ll also save cash on energy bills during the fall and winter.

Do you have rooms in your home that are always cold, regardless of how high you set your thermostat? There are many factors that can cause uneven heating in the home, here are some of the possible causes.

Uneven Heating

The Air Ducts Ductwork Are Leaking Or Are Undersized

If airflow to certain parts of the home is insufficient, you’ll experience uneven heating or cooling in those areas. An airflow imbalance will also cause your heating system to work overtime in order to compensate, which in turn will shorten the unit's lifespan and decrease its efficiency.

In order to create a balanced airflow a qualified HVAC technician will need to inspect and assess the effectiveness of your home’s ductwork by performing an airflow analysis.

Identifying leaks and blockages is also important, as leaks are a major contributor to inefficiency and uneven temperatures. If blockages are identified, they will be removed to restore airflow. Once the underlying causes of the imbalance have been identified, the appropriate repairs or replacement will be made to get your system functioning normally again.

Variable Speed Motors

Variable speed motors provide more even heating and cooling, and allow for more precise control of airflow throughout the home. By moving the air more slowly through the system, variable speed motors can help make a home’s air filtration and moisture control systems more effective. They adjust the system’s output based on the home’s heating or cooling needs. They can also be helpful in situations where uneven heating or cooling is actually desired. If there are rooms in your home that are rarely used, you can save money by keeping them at a slightly higher or lower temperature than the other rooms in your home. This involves “zoning,” which means customizing temperature settings for different areas of the home. In general, variable speed motors are the only systems that allow for zoning within the home.

Ensure Your HVAC System Is The Correct Size

Just as you’re experiencing discomfort due to uneven temperatures, your system is constantly trying to compensate, which means high utility bills and shortened system lifespan.

An improperly sized HVAC system may result in uneven heating or cooling. This could be the result of either an incorrect load calculation at the time of the system’s installation or a home’s heating and cooling needs changing over time. For example, it is common that an extra room is added or an area like an attic or basement is converted into living space. If your HVAC system is too small to properly heat or cool your home, uneven temperatures and system failures could result. To determine whether your HVAC system is properly sized, contact an HVAC professional for an up-to-date load calculation.
With natural gas costing around 50 percent less than heating oil, many homeowners are finding the initial cost of conversion worth the long term savings in fuel cost.

Connecticut Oil-To-Gas Conversion
While the price advantage of natural gas generally means a new gas system will pay for itself in as little as 5 years, there are other costs to consider:
  • The cost of the new equipment (gas-fired furnaces and boilers generally cost less than oil-fired equipment)
  • Installation cost
  • The cost to run a gas line to the house
  • The cost to dispose of the oil tank and old equipment
Other reasons to consider natural gas over oil include:

Smaller Footprint
Gas equipment typically takes up less space than oil equipment.

Federal and state tax incentives may be available for upgrading to high efficiency heating systems.

No more oil deliveries, gaps in service, negotiating with your oil company, or prepaying. Natural gas is always available.

Domestic Fuel Source
Unlike most heating oil, natural gas is an abundant domestic fuel source.

With a natural gas line you can reduce your utility bill by converting your electric clothes dryer, stove and water heater to less expensive natural gas.

Environmentally Friendly
Natural gas is the cleanest-burning fossil fuel and a highly efficient form of energy. Converting from oil to natural gas can reduces CO2 emissions by around 27 percent.

Gas Furnace Standing Pilot Flame

While electronic ignition furnaces have been around for a while now, your home in West Haven, CT, may still have a gas furnace with a standing pilot light that remains lit all the time. The standing pilot light works in conjunction with a thermocouple to control the ignition of the burners and the flow of gas. The thermocouple senses if the pilot flame is hot enough to ignite the fuel to the burner.

If you have an old furnace that uses a pilot light, it needs to be kept clean-burning and properly adjusted to ensure that the furnace operates safely and efficiently.

Inspecting a Gas Furnace Pilot Light Flame

Remove the furnace cover panel to expose the burner assembly and pilot. You should be able to see the flame of the pilot light. The first thing to check is the color of the flame.

  • A natural gas flame should be a bright blue color with a small amount of yellow at the very tip.
  • A propane flame will have more of a bluish-green flame with a tinge of yellow at the tip.
  • The flame should be strong enough to cover about 1/2 inch at the end of the thermocouple tip.
  • If the flame is too strong and not adjusted correctly, it will be blue and may make a hissing sound as the flame crosses the thermocouple. The pilot should be adjusted to reduce the intensity of the flame.
  • A yellow flame is caused by a lack of oxygen and incomplete combustion. If the pilot light is a weak yellow flame, it will not get hot enough to heat the thermocouple to the temperature needed to enable the gas valve to open. A dirty pilot tube tip often causes this problem.
  • A split flame is usually caused by a dirty pilot tube.
  • A draft usually causes a flickering or wavering flame. Check to see if there are sources of drafts in the room and take steps to reduce the effects on the furnace.

Space Heater SafetyDid you know that 80 percent of home heating fire deaths in the U.S. involve space heaters and that 32 percent of home heating fires are caused by space heaters? It is estimated that space heaters cause over 19,000 home fires, 360 deaths, and over 1,000 injuries a year.

Once a house fire starts it is only a matter minutes before it becomes life-threatening. By following a few safety steps when using a space heater you can avoid becoming a statistics.
  • Space heaters should never be closer than 3 feet to upholstered furniture, clothing, mattresses, bedding and other flammable material.
  • Place the space heater on a hard, level and nonflammable surface
  • Keep children and pets away from space heaters
  • Never leave a space heater running when you are away from home.
  • Plug space heaters directly into a grounded wall outlet without adapters or extension cords
  • Choose a model with features like a built-in thermostat that shuts the heater off when the room temperature is met and a thermal cut out switch that shuts the heater off if it gets too hot.
  • If you have kids or pets, a cool touch exterior can prevent accidental burns
  • Ensure there is a working smoke detector on every level of the home and test them monthly
