Frequently Asked Questions

What is HVAC?

HVAC stands for Heating, Ventilation and Air Conditioning. Give us a call any time you are experiencing heating, cooling or other indoor climate issues in your home.

How do I know when to replace my HVAC system?

Any HVAC system more than 10 years old is likely to be inefficient and costing you money, in higher monthly utility bills. If your system experiences problems frequently or breaks down often, give us a call so that we can take a look and determine if there are better, more cost-effective options. Sometimes replacing parts can solve the problem, but typically if it is an older HVAC system, replacing parts will not increase its efficiency.

How often should I have my HVAC system inspected?

Your system should be inspected at least once a year. There are usually preventive maintenance items that need to be performed such as cleanings, adjustments, replacements, etc. This inspection and preventive maintenance will greatly reduce the chances of failure and increase the life of your HVAC system. Give Hays HVAC a call to schedule your yearly inspection today.

What is the best way to find an HVAC contractor?

Many of the standard methods that people used in the past to find contractors for their home such as The Yellow Pages, classified ads in newspapers, etc. are outdated and not very useful. Look online for the best and most up-to-date information on various contractors. Give them a call and make sure all your questions get answered. We at HaysHVAC offer free estimates and are more than willing to answer all your questions.

Is there anything I can do to diagnose my problem before calling HaysHVAC?

Yes, you can check your circuit breakers to make sure that your system is still receiving power. Make sure that your unit’s air filters are clean. Make sure that your vents are open and unobstructed. And of course, check your thermostat to make sure the temperature is set to the appropriate setting. Some modern thermostats also give a readout on the status of the system, so that may help diagnose the problem as well.

What is SEER?

SEER is an acronym Seasonal Energy Efficiency Ratio. SEER measures the efficiency of air conditioners and heat pumps. Higher SEER numbers mean higher efficiency and greater energy savings for you. Manufacturers usually build systems with SEER ratings of 13.0 rating or higher.

What is “Energy Star?”

ENERGY STAR is the federal government (EPA) standard for heating and cooling products. An “Energy Star” designation on a product mean that it meets the federal high-efficiency and energy savings standard. Investing in such products may result in lower energy bills for you.

What is the average lifespan of heating and cooling equipment?

While lifespan can vary depending on how much care and maintenance you do for your system, most systems have a rated lifetime of 10-12 years. You should, however, get your system inspected for any problems and adjustments ideally once per year, but at most after 5 years. Regular inspections, adjustments and replacements are part of the Preventative maintenance process, and can prolong the life of your equipment.

How often should I clean my furnace?

You should get your furnace cleaned and checked once per year. However, if your system is older, it may require more frequent checking and cleaning. This is very important because your furnace can leak Carbon Monoxide – a deadly toxic gas, from cracks within your furnace. For the safety of everyone in your household, you should have your furnace regularly checked.

Will I be able to put plants around my outdoor unit?

Yes, in fact you encourage you to do so. A unit that is in the shade of plants actually uses less electricity than one that is in the open sun. But just make sure that you place the plants far enough from the unit so as not to obstruct airflow – at least 3 feed away.

How often should the filters be changed on the unit?

Different filters have different changing requirements. You should replace the unit as often as instructed. You should, however, inspect your filter more often than you change them. Most filters should be changed monthly. This is important because a dirty filter will decrease airflow, change the pressure in the system and adversely affect your energy bills.

When I am not home or on vacation, should I just turn off the system to save energy?

It is not advisable to turn the whole system off. You may want to simply turn the temperature so that it is nearer to the outdoor temperature. This way, your system will use less energy.

How do you guys determine the size of my HVAC system?

When our team member evaluates your home, the factors he looks at when determining the size of the proposed system are: square footage of your home, local climate, amount of shade around your home, humidity levels, insulation level, number of occupants, heat generating applicances, number of window, etc. We look at all these factors and make a custom recommendation especially suited to each of our customers.

How do I protect my family from Carbon Monoxide poisoning?

As you may or may not know, Carbon Monoxide is a colorless and odorless gas. It can cause nausea and dizziness at low levels and can be fatal at high levels. You should install a carbon monoxide detector wherever there may be an open flame in your home – such as a gas or oil furnace, gas stove and fireplace. There should also be lots of air flow in rooms where such appliances are being used. Our service professionals can help you assess carbon monoxide dangers and install carbon monoxide detectors in your home.

What are the signs of poor air quality in my home?

The question to ask is how comfortable are you in your home? If you are too cold, hot, if there are odors or if you suffer from allergies — these can all be signs of poor air quality.
