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.

Fantastic team. Completed the job as per the specifications and in under 3 hours. Highly recommended Twintech.

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.

Greg came over at 9:30pm to rescue my daughter and I from a horrible experience with Enercare that evening. He was professional. Kind. And got us what we needed quickly and at an afford price. I would 100% recommend calling on Greg and his team for any of your heating and cooling needs in the future!!

Installed a great hot water heater when our old one failed. When my furnace died during cold weather they showed up quickly and my house was warm before my wife got home. :)

I dont usually right reviews but when you receive service like this I felt it was a must. Honest and fair. I Have 4 children and on Xmas eve my furnace stopped working and a gentleman came out and got me up and running so at least we would have heat for the holidays. As promised he would replace my furnace early in the new year. The job was completed on time, great price for quality furnace and extremely clean and professional job. Would have never known anyone was in the house. Not a spec of dust or mess from lugging out an old rusty furnace. If you have any ac or heating concerns twintech is your only option. I was royally impressed with and Im sure you will be too.

This Company is terrific. No high pressure sales and they deliver exactly what they promise to deliver. The new furnace is great and we now get consistent temperatures throughout the house. The installers were great and very efficient and completed the work on schedule on the promised day. Everyone representing this company was very aware of their presence in our house and worked diligently to keep our home as uninterrupted and as clean as was humanly possible. We did not need to go around the house to clean up after they left, what a nice surprise. We have had follow up by the company to ensure everything is to our satisfaction. How unusual in today's environment. The impression left by Twintech is that they care about us and our home. This is so refreshing in today's high tech world. Out thanks go out to Dave in sales and G, G, and P (the installers).

The entire process was prompt and professional, from the initial quote to the installation of the new furnace. The team installed the new furnace and removed the old one in approx. 4 hrs. The guys were very knowledgeable and gave me lots of information. I have used Twintech before for a new A/C installation and new I was in good hands.

The overall experience dealing with this company was great from start to finish when getting a new furnace and ac this year. Everything was clearly explained to us during our consultation with Dave and there were no surprises with added costs. The work was done as expected and their response time to inquiries were very timely generally within a few hours or less. They are all very professional and was a pleasure to do business with them. Highly recommend to anyone looking for honest quality professional service.
