9 Things to Check Before Calling an HVAC Contractor

When your HVAC system stops working, it can be a nightmare. Getting it fixed quickly is essential, but before calling an HVAC contractor, there are a few things to check. Davis Mechanical Contractors, a professional HVAC contractor with years of experience, wants to provide you with a list of things to check before giving us a call. By checking these things first, you can save yourself time and money. You can also call us if you need air conditioner repair in Alvin, TX, and surrounding areas.

  • Check Your Thermostat

If your HVAC system isn’t functioning correctly, the first thing to check is your thermostat. Ensure it’s set to the correct temperature and in the correct mode (heat or cool). If your thermostat is malfunctioning, it could be the cause of the problem.

  • Check Your Air Filter

A dirty air filter can block the airflow, which can cause your HVAC system to work harder than it should. It can result in higher energy bills and wear and tear on your system. Check your air filter and replace it if it’s dirty.

  • Check Your Circuit Breaker

If your HVAC system isn’t turning on, check your circuit breaker. It’s possible that the breaker has tripped, which can prevent your HVAC system from receiving power.

  • Check Your Air Vents

Check your air vents if your HVAC system is running but not cooling or heating properly. Make sure they’re open and unobstructed. If your vents are dirty or obstructed, it can restrict airflow and make it harder for your HVAC system to cool or heat your home.

  • Check Your Ductwork

Check your ductwork if your air vents are open and unobstructed, but your HVAC system is still malfunctioning. Look for signs of leaks or damage. If your ductwork is damaged or leaking, it can cause your HVAC system to work harder than it should, resulting in higher energy bills and more wear and tear on your system.

  • Check Your Outdoor Unit

Your outdoor coils can become clogged with dirt and debris over time, reducing their efficiency and making it harder for your HVAC system to cool or heat your home. Clean them off and make sure they’re free of dirt and debris.

  • Check Your Refrigerant Lines

If your HVAC system is not cooling or heating properly, it may indicate a leak in your refrigerant lines. Look for signs of leaks and check the pressure to ensure it’s within the manufacturer’s specifications.

  • Check Your Windows and Doors

Check your windows and doors if your HVAC system is not cooling or heating your home correctly. Make sure they’re closed and sealed properly. If your windows and doors are not sealed properly, it can allow hot or cold air to enter your home, making it harder for your HVAC system to keep up.

  • Check Your Insulation

Check your insulation if your HVAC system is not cooling or heating your home correctly. Make sure your insulation is properly installed and in good condition. Poor insulation can cause hot or cold air to enter your home, making it harder for your HVAC system to keep up.

By checking these things before calling an HVAC contractor, you can solve the problem and save time and money. However, if you’re still experiencing problems after checking these things, Davis Mechanical Contractors are here to help.

Top six HVAC issues

Six common HVAC issues that may require heating replacement in Alvin, TX, if overlooked and how to recognize them.

• Dirty and clogged AC filters

Each home has an adequate HVAC system that produces clean air and the right temperatures. If air filters aren’t replaced frequently, they might harm an HVAC system’s performance. The furnace may overheat and lose efficiency due to inadequate air ventilation. A dirty air filter can also contribute to the development of allergies and respiratory issues.

• Leaking water

When in use, an HVAC system produces a lot of condensation. Any condensation should be moved to the drain lines and removed from the building, but if a line is compromised, your system could leak, leading to breaches in your walls and internal architecture. 

Clogged drain lines and a lack of preventative maintenance are two causes of water leaks. If you’re having one of these HVAC problems, contact our specialists by searching for HVAC contractors near me and look for Davis Mechanical Contractors in the top results.

• Ineffective thermostat

Your thermostat serves as the air conditioning’s control system. Both programmable and non-programmable thermostats come in a wide range of designs, and they all have different interactions with your entire system.

The main power source for programmable thermostats is a set of batteries that must be frequently changed. The first problems should be resolved by rapidly consulting the manual and the unit’s instructions; if they persist, our heating replacement in Alvin, TX, can promptly diagnose them

• Unclean evaporator coils

The majority of HVAC issues can be avoided with routine maintenance. If your evaporator coil is unclean, your furnace and air conditioner may operate less efficiently and more diligently. 

Moisture leaks can be fixed by cleaning unclean filters or air vents. If you seek professional assistance for a heating replacement in Alvin, TX, contact Davis Mechanical Contractors

• Strange HVAC sounds and odors

Strange noises from your HVAC system may indicate frequent problems, such as inducer motor bearing failure or a malfunctioning blower motor. These sounds may include whining, rattling, or squealing, and depending on the reason, they may point to the need for a heating replacement in Alvin, TX, sooner or later. 


A faulty fan switch, clogged heating and cooling systems, or problems with ventilation can all contribute to certain noises. Either way, you shouldn’t dismiss any unexpected, unfamiliar noise your air conditioner makes.

• Ignition or pilot issues

The ignition efficiency of an HVAC system is one of its riskier components. You’re endangering yourself and your loved ones if you don’t perform routine maintenance. Numerous factors, like a dirty pilot light, a malfunctioning flame sensor, short cycling, or a clogged fuel supply, might cause ignition issues. 


In such situations, the unit should only be fixed by a professional after determining the problem. An ignition component may simply be wearing out, or it may be a gas leak, which can be fatal. Contact our professional or search for furnace contractors near me to resolve the issue.


In either case, routine maintenance is essential, particularly given that those ignition problems are connected to hazardous substances like natural gas and high voltage.

The Most Common Reasons for HVAC Technician Service Calls

When it comes to dealing with your HVAC system, there are two things you should keep in mind. First, some issues can be resolved simply by removing debris and dirt from the filters and coils, which you can do DIY. You only require the required tools and equipment. 

Second, the first assertion may not always apply in every situation you may face in the future. There will always be problems that only professionals can solve, and attempting to solve them on your own may end in dangerous consequences. This is why some homeowners prefer to contact HVAC companies or other service providers in their neighborhood.

Unusual Noises

Some residents have complained about noises coming from the boiler, heat pump, or air conditioning system. While your HVAC may occasionally emit sounds that are quite natural if these noises do not cease, you should consider contacting an expert or HVAC contractor near you to assist you in diagnosing the problem, determining the likely causes, and providing suitable remedies. The sounds you’re hearing could indicate that a component is clogged with trash or has loose equipment within.

Malfunctioning Thermostat

When you notice that your HVAC system isn’t working as well as it should, you should consider that it could be due to an issue with the thermostat. You can fix it by replacing the old batteries with new ones or by contacting a technician. The latter is more secure and protective. While it may seem easier to simply read the handbook, you should remember that hiring a professional will be more cost-effective because you will prevent further repair and damage expenditures.

Leaks of Water

HVAC (heating and cooling) units generally condensate, and it is normal for them to produce moisture as they operate. Condensation flows through drain pipes, ensuring that there is a good drainage system. Clogs and cracks in the drain lines, on the other hand, produce leaks to the unit, which can cause major damage to your HVAC units.

Infections Caused by Molds

Moisture is produced by your air conditioner repair Alvin TX units, as previously stated. As a result, if your devices are not properly and routinely cleaned and maintained, they will always draw mold. Molds can induce allergic reactions in both the skin and the lungs. To ensure complete cleaning, you must clean the unit yourself or engage a professional cleaner.
