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.

I had cold and hot spots all over my 70 yr old home. My furnace is quite new and Greg optimized the fan and furnace. The original installer just took it out of the box with factory settings and installed it- basically running at 50% of capacity. Greg also routed heat into my laundry room, yeah - so now I can renovate laundry room - thanks Greg. He is honest, professional and knowledgeable. I will be calling him back in the spring to optimize my AC as well.

Wonderful from beginning to end. I tend to fret and worry about home improvements but the excellent team at TwinTech put my mind as ease. They listen, they are patient and best of all ... the work they did is amazing! I chose the Goodman 80K BTU 2 stage furnace and the matching Goodman air conditioner. Greg, Grant and Poitr "Peter" arrived on time, took great care, explained everything to me and they answered all of my questions. They carefully adjusted the factory settings to optimize the furnace for my house and they also checked the duct work in the basement. Dave, the Sales Manager, came by to say "hello" and to see if I was happy. YES, I am happy with the work! The furnace is very quiet. I have it running on low just to circulate the air in the house and it's so much quieter than my old furnace. When I need new duct work for an upcoming basement renovation TwinTech will be my first choice. I highly recommend TwinTech. PS. They were even nice to my dogs.

Greg was prompt on the scheduled day of installation and the work was done well within the time estimated beforehand. Installation was neat and the equipment and scope of work was as specified in the quote. One item I must point out is that we were faced with a "No Heat" situation the day before the scheduled installation and Greg came out to address it free of charge. Not only that, but he also corrected an installation fault with our smart thermostat that was not part of the original job, again free of charge.

Greg came by to do a routine furnace checkup. He was very knowledgeable and professional, letting me know what's being checked/adjusted and giving me tips to ensure everything runs smooth. Very honest and upfront about what's working fine vs. what may need to be fixed/replaced. He didn't attempt to up sell anything that wasn't necessary. I'm glad to have finally found someone I can trust and rely on for all my HVAC needs - furnace, A/C, and hot water tank.

I'm very happy with the work that was done. Everyone from salesperson to the installers were friendly and professional. They were on time and cleaned up the job site after it was installed. They also answered all my follow up questions promptly. I wouldn't hesitate to work with them or recommend them again.

Thanks to the team at Twin Tech for a great job installing my new heat pump/ac unit. The guys were very polite and professional. When they left you would never have known they had been there except for the new Mitsubishi unit on the wall!! would highly recommend the Twin Tech team.

Very impressed with this company. They show up on time , kept my place clean and after they left it looks like they were never there. Very professional team. Those people know what they doing . Their installation was on the highest standard. They are very knowledgeable especially they're worker Peter. I strongly recommend this company to everybody. After the installation I receive the call making sure I'm satisfied with their products and their job. Bravo!!!

Greg and his brother were referred to us by a friend. They arrived when they said they would, did an exceptional job and left the place as tidy or tidier then they found it. Their professionalism is only surpassed by their kind and friendly demeanor. Even after several calls to help me with my high tech thermostat I feel that I could always call with any concern (No one responds to my texts as quickly as Greg) and have a friendly helpful response. I found out their grandfather started the company and now as a 3rd generation company, they are doing their grandfather proud. I would highly recommend Twintech over any other hvac company out there.
