Repair or Replace?

When to Repair you air conditioner:

Old air conditioning equipment becomes expensive to repair and offers no guarantee that additional problems are not close behind.

If you plan on moving soon, you may not get your investment price from a replacement air conditioning unit when you sell.

A replacement that involves other trades may be cost prohibitive. In rare situations, a new air conditioning system can require significant remodeling.

The system has been trouble free thus far and looks to be mechanically sound still.

When to Replace your air conditioner:

If the equipment has reached 6 years old be careful not to throw good money after bad with repairs. The average life span of an air conditioning unit is 6 to 12 years.

If the system is older than 12 years, major improvements in efficiency could be saving you BIG money. Super efficient, modern equipment can save $1,000 or more per year.

If you are not comfortable. Today’s modern air conditioning comfort systems can virtually eliminate hot and cold areas, high and low humidity, bad air quality, high utility bills, noisy indoor and outdoor equipment, and much more.

If your system does not have variable air flow. Variable air flow is the key to comfort. New systems keep the air moving, adding to comfort and helping save money.

If you are concerned about break downs. When an old system fails under the intense summer heat, a replacement air conditioner can easily be a week to 10 days away

Replace before the summer crunch hits. Do not pay higher summer prices. Many small air conditioning contractors prey on homeowners who must replace in summer when reputable companies get busy.

If family members have allergies, asthma or other air quality health concerns. Indoor air quality can be improved throughout the whole house by 100 times with today’s high tech IAQ technology and air conditioning products.

Replace before manufactures and utility companies rebates run out. Equipment manufacturers rebates are usually available through May. APS and SRP rebates can be discontinued at any time.

Common Heating Problems

1. Thermostat issues
Thermostats are a common source of heating problems. Thankfully, thermostats are usually not very expensive to replace. Any of the following symptoms could mean that your thermostat is malfunctioning:

*Room temperature does not match thermostat setting

When room temperature is noticeably higher or lower than the set temperature on the thermostat, it could mean that the thermostat is not calibrated, or it is installed near a heat source or a drafty window, causing it to receive a faulty reading.

*Heat pump cycles on and off too frequently

If your heat pump cycles off and on too frequently, and your blower and filters are clean, then your thermostat is probably the culprit.

*Heat pump blower runs continuously

This could be an indication of a malfunctioning thermostat, or the limit switch on the heat pump itself could be broken.

*Room temperatures fluctuate drastically

If you have your thermostat set at one level and your room temperature is going up and down more than 3 degrees F, the heat anticipator on your thermostat may be broken or need adjusting.

2. Drafts or insulation problems

Leaking windows, drafty doors, and overall poor insulation are major causes of heating problems. Homeowners waste hundreds of dollars a year on heating and cooling because of poor insulation.

3. Carbon monoxide leaks

Older furnaces (10 to 15 years old) have a higher likelihood of having a rusted heat exchanger which could have miniscule cracks, leaking carbon monoxide. It is very important to have a carbon monoxide detector, to make sure to have your furnace checked, and to have the heat exchanger examined for rust and cracks. Sometimes the cracks are very small and difficult to spot, so at a very minimum, a carbon monoxide detector is vital when dealing with a gas furnace. The certified professionals at AbleAir-1 can install a carbon monoxide detector and check out your furnace. Your furnace should be checked biannually to prevent problems—ask about our competitive maintenance plans.

4. Air flow problems causing some rooms to be warmer or colder than others

You may be able to solve this problem by manually adjusting the vents in your home (opening or closing a vent just a bit). However, overall flow problems are often caused by clogged or dirty filters and coils. You should invest in your HVAC system by having it maintained biannually, which will also extend its life. AbleAir-1 offers affordable maintenance packages that will prevent this problem.

5. Heating system pilot light or ignition control problems

When your heat goes off suddenly it’s often because of a malfunctioning pilot light or ignition control. Because of the potential danger involved, this is not a job that the average homeowner should undertake. Call our certified heating technician at Langford’s Mechanical Services for immediate assistance.

The Five Most Common Air Conditioning Problems

Although there are potentially hundreds of reasons why your home’s central air conditioner may need to be repaired, there are a few reasons that are quite common. Knowing what they are may help you to understand what a technician is referring to when you need to discuss the options for correcting the problem. Here are the top five problems that may cause your air conditioning system to break down. Please review these considerations and determine whether you need to schedule an HVAC inspection.

1. Faulty wiring

Improper, haphazard or uncertified A/C wiring is dangerous and a potential fire hazard. Bad wiring often prevents the system from getting power, or can trip the circuit breaker.

2. Low refrigerant

Refrigerant (more commonly referred to as Freon) is the chemical that cools the air. Low refrigerant may indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that means there is a leak. All refrigerant leaks should be located and repaired.

3. Outside fan is not working

The outside fan is responsible for transferring the heat from your home to the outside air. If the fan on the outside unit doesn’t run, proper heat transfer is not taking place and the air conditioning compressor may overheat and trip the safety overload. Worse yet, it may cause internal damage to the compressor.

4. Outside unit not functional

This typically indicates lack of power, contactor problems or even a faulty thermostat.

5. Frozen Inside coil

A frozen coil often indicates a problem with the airflow, such as restrictions caused by dirty air filters or blocked return air ductwork. Frozen indoor coils could also be caused by low refrigerant.

In many cases, the only way a homeowner can prevent these common problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be detected during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can quickly diagnose the problem area and make the necessary repairs.
