HELPFUL TIPS FOR DEALING WITH HVAC PROS IN LEAGUE CITY, TX

Nothing in your house affects your comfort more than your heating and cooling systems. But most of us pretty much ignore our heating, ventilation, and air-conditioning (HVAC) equipment unless the heater conks out during a blizzard or the air-conditioning goes on the fritz in the middle of a heat wave.

When not maintained, even the best HVAC system can cost you by wasting energy. And during the boiling summers in League City, Texas, power drain from an unmaintained AC unit can substantially increase your utility bills.

Some maintenance tasks are simple while others require a repair technician trained in air conditioning and heating systems, like the staff at Doctor Cool & Professor Heat. You’ll also need an HVAC contractor in the League City, Texas area on speed dial if your system is at the end of its useful life. Here are some tips from Today’s Homeowner for dealing with your HVAC equipment and the professionals that service it.

Routine HVAC Maintenance

The good news is that most HVAC systems don’t require too much attention.

Heat Pump

A heat pump only needs a yearly service call by a HVAC technician who will:

• Check the belts, and replace them if needed
• Check and replace the filters
• Oil any moving parts
• Inspect the wiring

Gas-Fired Furnace

A gas-fired, forced-air heating system has simple requirements, too. Furnace filter should be changed every month or two during heating season, and the circulating fan oiled once a year. Call in a pro every other year to check the:

• Heat exchanger
• Flue
• Ducts
• Adjust the burner

Oil-Fired Boiler

An oil-fired boiler requires annual maintenance by a League City, Texas area HVAC technician to:

• Clean the flue
• Change the fuel filter
• Clean and adjust the fuel jets

Air Conditioner

Air conditioning units are a little less maintenance intensive. At the beginning and end of each cooling season, you should:

• Clean or replace the air filters
• Vacuum out the unit
• Lubricate the motor
• If the unit isn’t cooling properly, have the refrigerant pressure checked.

Arrange for a service call with Doctor Cool & Professor Heat before the start of heating or cooling season. You’ll get better attention and have more flexibility when scheduling the appointment.

What to Look for When Hiring a HVAC Company in League City, TX

When hunting for a company to maintain your system, look for one that designs, installs, and services the type of system you have. Full service companies also tend to be up to date on the latest advances in the field.

Besides checking that liability insurance and workers’ compensation policies are in force, ask for recommendations or check with neighbors, friends, and family in the League City, Texas area who have used the company over several years. Find out:

• How well did the system run under the company’s care?
• Did the technicians leave the working area clean?
• How quickly did the contractor respond to emergencies?
• Were the service people punctual when you called with a problem?

A quality provider will have an emergency number that’s staffed 24 hours a day, seven days a week and enough technicians to respond when the weather is awful and the calls pile up.

Buying a New HVAC System

Heating and cooling equipment is designed to last at least 15 to 20 years. If your system is older than this, you might want to have its condition assessed. Although replacing HVAC equipment is a major expense, modern systems operate much more efficiently than the older units they replace.

Most HVAC contractors specialize in designing and installing the systems of a few manufacturers, so no one shop is going to carry every major brand. For example, Doctor Cool & Professor Heat specializes in Trane and Carrier HVAC system installations. But before you worry about the equipment, it makes sense to find contractors in the League City, Texas area that are knowledgeable and service-oriented.

Start your search by asking neighbors, friends and family what companies they hired to replace a furnace or air-conditioning system. If they were happy with the installation, ask their contractor to come over and talk to you about heating or cooling your house.

You should meet with at least two contractors, and hire someone who installs products from at least two manufacturers. Don’t forget to consider your service company, if you have one. You’re under no obligation to hire the firm for the new system, but its technicians do have a good understanding of the conditions in your home.

When picking a contractor, remember that sizing an HVAC unit by matching it to the home and existing ducting requires skill and experience. A poor design typically results in a system that doesn’t deliver a consistent temperature from room to room and costs more to operate.

But it can be even more serious than that. In very tight houses served by ductwork, poor design can lead to backdrafting, a dangerous situation where flue gases are sucked back into the house.

Most HVAC shops are small, so the owner should be involved with the system design and either participate actively in the installation or inspect it when it’s done. You don’t want your system designed by a salesman with no field experience.

Any Texas area contractor you’re considering should also offer these products and services:

Heat-Loss Calculation

This process estimates the BTU capacity needed to heat or cool your home. The calculation should include:

• The amount and type of insulation in the walls, attic and floors.
• The type, number, and location of windows and doors.

This data is combined with your regional climatic conditions to determine the size unit you need. Software has made these calculations relatively easy. HVAC technicians who don’t perform them often specify oversize equipment to be safe. That’s dollars out of your pocket now and each time you get an utility bill.

Energy Advice

When sizing an HVAC unit, a good contractor will advise you of energy upgrades, such as adding another layer of insulation to the attic. These may allow you to buy a smaller HVAC unit. Although it may not be cost effective to buy the most energy efficient unit on the market, there are minimums you should shoot for. Here’s what a contractor should offer:

• An AC unit (if below five tons) with a 14 SEER or higher.
• A high-efficiency, natural gas heater with an AFUE of around 90 percent.
• A fuel-oil burner with an AFUE of around 85 percent.
• A heat pump with an 14 SEER and 8.2 HSPF.

Automatic Controls

A programmable or setback thermostat (around $40), which contains a timer, should be used regulate all HVAC systems.

Payback Calculations

A quality HVAC contractor will show you payback calculations for the various units he offers, and those calculations should give you estimates of seasonal operating costs.

Variables the contractor will use in his calculations should include:

• Your regional heating or cooling load.
• The heating or cooling capacity of the units you are considering.
• The cost of various types of energy to allow you to compare the costs of electric, gas, and oil.

Once you receive itemized estimates, compare the costs, and do some research on equipment. Start by visiting U.S. Dept. of Energy and Consumer Reports websites, or contact your utility company for comparative lists.

Look at operating efficiency and costs as well as consumer-rated reliability. Then compare your knowledge of the contractors involved and make your decision.

Understanding Hot & Cold Tech Speak

Confused by HVAC lingo? Believe it or not, it’s meant to make understanding and buying the equipment easier. These terms allows you to compare apples to apples among units in the same fuel category. Knowing what the terms listed here mean will come in handy:

Seasonal Energy Efficiency Ratio (SEER)

The Seasonal Energy Efficiency Ratio (SEER) rates how many BTUs an air conditioning unit will remove for each watt of electricity consumed. The higher the SEER, the less you spend on operating costs. Federal law mandates a minimum SEER of 13 for all new air conditioning units.

Tonnage

An air conditioning ton equals 12,000 BTUs per hour. That means a three-ton air conditioner can remove about 36,000 BTUs of heat per hour from your home.

Annual Fuel Utilization Efficiency (AFUE)

The Annual Fuel Utilization Efficiency estimates how much heat a unit delivers for every dollar spent on fuel. The higher the AFUE, the lower your heating bills.
