HVAC Maintenance: Common Problems You Might Encounter
Posted On: March 2, 2022
The battle against heat and humidity can be quite common during the warmer months. Some homeowners rely on their HVAC systems to keep them cool and comfortable, even on the hottest of days. This is why when HVAC systems break down, it is not always a bearable situation.
Here are several common HVAC problems that we should be aware of:
THERMOSTATS
Before checking for other problems in an HVAC system, check first the thermostat if it is turned on and set correctly. Thermostats control an HVAC system, so if it is not functioning correctly or if it is not turned on, then your AC unit won’t likely function well either.
REFRIGERANT
If your air conditioner unit is blowing air but not a cool one, then you may be low on refrigerant or there is a leak. One of the most commonly used refrigerants or coolants is Freon. If you own a unit that was manufactured prior to 2010 and is low on coolant or has a leak, then it can still qualify for a recharge (or more Freon) given that the unit is still functional outside the low coolant level. If it is not functional in addition to the low leak, then it has to be replaced with a newer unit made after 2010. Newer models now use a different type of Freon called R410a.
Only licensed technicians are allowed to purchase Freon so if you need professional HVAC assistance, then we are the right experts to call.
POOR HVAC MAINTENANCE
Poor maintenance is one of the leading causes of system malfunction or worse, system failure. Regular upkeep e.g. air filter replacement is necessary. Air filters catch dirt and allow clean air to pass through the system. It is important that you check and replace your air filters regularly – or else they can become blocked. When air is blocked, expect your HVAC system to perform poorly. It can also result in a frozen system, as cool air is unable to be distributed throughout the unit. Ideally, air filters should be changed every 1 to 3 months, depending on usage. The more you run the AC or you have the fan on, then the sooner your filters should be replaced.
ELECTRICAL FAILURES
When HVAC systems are turned on and off on a frequent basis, you will most likely experience electrical component failure. An AC unit has three components: compressor, condenser, and blower motor. These components disable or enable the heating and cooling functions when an HVAC system is turned on or off. The constant switching between on and off causes the components to wear out faster.

Dave was very pleasant to deal with and Twintech responded quickly when our furnace needed to be replaced ASAP. Installation was done on time and the crew were neat and tidy. We now have a great furnace that suits the needs of our family.

When your furnace kicks in over the holidays and you're not sure where to turn.. I'm so thankful that this company returned my phone call. I appreciated their transparency and clarity which allowed me to make an informed decision. With various quotes thrown at you, it can be difficult to make the right decision and trust the solutions offered by different companies. TwinTech spoke the truth and delivered on their word. Neat, timely and clean service; the peace of mind I needed during a very cold holiday season. I highly recommend them!

Pulling a old unit out and installing a modern heating system! Required drilling holes in the wall for the newer pipes. We went from 70% (I am willing to bet it was far less due to lack of maintenance and just old) to 96% newer . It now feels warmer and more pressure and we use to run extra heaters and feel as though they are not necessary!

I received three quotes before deciding to choose Twintech. Dave's prices was much more reasonable than the competitors. I most appreciated their honest recommendations. Others tried to oversell their products and services. Thank you Dave!

My 19 year old furnace stopped working when the cold weather hit in November, and I was left without heat. I interviewed several companies and found TWINTECH HEATING and COOLING to be very knowledgeable, quick to respond to my inquiries and very competitively priced.
Dave provided all of the information and pricing ahead of time and set up the appointment for the installation. Greg and Mitch arrived on time to do the installation and worked quickly and efficiently to complete the job.
After the completion of the installation, Dave followed up to ensure that everything was working well and that I didn't have any concerns.
Overall, this was a low-stress and flawless experience from start to finish. I would highly recommend TWINTECH HEATING and COOLING to anyone that requires a new furnace.

Our 20 year old furnace broke down during the first cold weekend this past November and our usual HVAC company never returned our phone call. Their loss, missing out on a sale since we didn't want to spend much fixing an old furnace and our 40 year old air conditioner was also long overdue for replacement. We proceeded in obtaining three different quotes for furnace and air conditioner replacement, and proceeded with the one we received from Twintech.
Dave was friendly, knowledgable and accommodating to our schedule and provided with us with a price that fell in the middle of the three quotes that we had. We felt that the Amana furnace and air conditioner he quoted us on were the best products and value offered to us and felt most comfortable with the professionalism and reputation of Twintech.
Greg, Grant and Mitch were at our house for installation the day after we decided to proceed. The guys were friendly and informative, the job was completed efficiently and workmanship appears excellent. Our house is certainly much more comfortable with the new two-stage variable speed Amana furnace compared to the old clunker! And, we're looking forward to enjoying the new air conditioner once summer rolls around again. Thanks Twintech!
