HVAC Maintenance: Common Problems You Might Encounter

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 have used Twintech many times over the years. They always arrive quickly and get the issue fixed. The most recent incident was when my air conditioner broke last week I called Greg at 11:30am and he was at my home by 2:30pm he had the unit fixed by 3:30pm. Twintech are very reliable and honest and they are experts in the field. I have already recommended them to many of my friends. I would not use anyone but them for my heating and air conditioning issues.
I would highly recommend these guys, professional, fast and competitive pricing. I moved into this place with no working AC unit with a 8 month baby, he was able to come with in a week to fix even in the busy summer days. He really values his customers , I am already recommending to my neighbors.
Very impressed they arrive to quote even though I had forgotten to call them back to confirm date & time. They showed the day before installation to deliver the unit. Returned the next day as promised at 9am. Project was completed in a professional manner. They even fixed a few things that they noticed were not installed correctly, or to code by previous heating & air contractors we had at our residence before. Would recommend this company to everyone!
Greg removed old oil furnace and oil tank from basement relocated new Napoleon propane furnace to allow duct work to be rerouted to a much more suitable location. Moved air conditioner to the new furnace. Dave recommended two available grants to assist with cost. They kept to their original quoted price which was substantially lower than a competitors for the same furnace and work. They completed the work as stated when stated and left the area clean and tidy. We are very pleased with the outcome.
Twintech installed a Goodman furnace and ac init. Very professional install, both units are working well.
We had Grant and Greg Dainty quote to replace our 20 yr old furnace. I have known them for years and have had other jobs done by them ( AC and Pool Htr). The price was very reasonable and the job was completed in one day.
TwinTech was the right choice. Our consultation with Dave set the tone. Professional and knowledgeable, we even received a follow-up call within hours of our install completion, wow! TwinTech arrived as scheduled to install our A/C unit. Within minutes of arrival Greg noted and explained a few out of code faults on our furnace installed by another company, problems fixed, thanks TwinTech. Greg, Grant and "Subaru" Pete were meticulous start to finish. Highly recommended!
Twintech replaced our aging +20 yrs old Furnace & AC with the variable high efficiency Napoleon Furnace matched with the Goodman AC. Sales guy ,Dave was great, gave a no pressure estimate, explained about the Government Rebate program which they took care of completely including arranging the home energy audit. On the scheduled day Greg and his team arrived on time, did a great job and completed the same day , extremely professional and courteous, cleaned up everything , tested the system, Greg took his time to explain the setup. Very impressed with the Napoleon Furnace 9600 which did a great job in maintaining a comfortable temperature last winter and now with the hot weather the Goodman AC cooled the house in much less time than the old AC unit could ever. From start to finish Twintech were great and have no hesitation in recommending them 100%.
The Twintech team did an excellent job installing our new Goodman air conditioner. They were polite and professional. Greg was knowledgeable and clearly experienced. Thank you Twintech for bringing our cooling system up to current regulations. Job well done!
Dave from TwinTech was very knowledgeable, professional and thorough in the buying process. He helped us to identify the best furnace for our home and our budget. When we needed a new filter a year later and seemed to have a problem finding the right one, I called Dave up and he delivered a filter to me the next day! The cost was on par with other retailers, but it was this unexpected personal service that really was impressive. The furnace? Works like a charm.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.
Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers.

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all!

I definitely recommend TwinTech!
